Historical Research

Definition:

Historical research is the process of investigating and studying past events, people, and societies using a variety of sources and methods. This type of research aims to reconstruct and interpret the past based on the available evidence.

Types of Historical Research

There are several types of historical research, including:

Descriptive Research

This type of historical research focuses on describing events, people, or cultures in detail. It can involve examining artifacts, documents, or other sources of information to create a detailed account of what happened or existed.

Analytical Research

This type of historical research aims to explain why events, people, or cultures occurred in a certain way. It involves analyzing data to identify patterns, causes, and effects, and making interpretations based on this analysis.

Comparative Research

This type of historical research involves comparing two or more events, people, or cultures to identify similarities and differences. This can help researchers understand the unique characteristics of each and how they interacted with each other.

Interpretive Research

This type of historical research focuses on interpreting the meaning of past events, people, or cultures. It can involve analyzing cultural symbols, beliefs, and practices to understand their significance in a particular historical context.

Quantitative Research

This type of historical research involves using statistical methods to analyze historical data. It can involve examining demographic information, economic indicators, or other quantitative data to identify patterns and trends.

Qualitative Research

This type of historical research involves examining non-numerical data such as personal accounts, letters, or diaries. It can provide insights into the experiences and perspectives of individuals during a particular historical period.

Data Collection Methods

Data Collection Methods are as follows:

• Archival research : This involves analyzing documents and records that have been preserved over time, such as government records, diaries, letters, newspapers, and photographs. Archival research is often conducted in libraries, archives, and museums.
• Oral history : This involves conducting interviews with individuals who have lived through a particular historical period or event. Oral history can provide a unique perspective on past events and can help to fill gaps in the historical record.
• Artifact analysis: This involves examining physical objects from the past, such as tools, clothing, and artwork, to gain insights into past cultures and practices.
• Secondary sources: This involves analyzing published works, such as books, articles, and academic papers, that discuss past events and cultures. Secondary sources can provide context and insights into the historical period being studied.
• Statistical analysis : This involves analyzing numerical data from the past, such as census records or economic data, to identify patterns and trends.
• Fieldwork : This involves conducting on-site research in a particular location, such as visiting a historical site or conducting ethnographic research in a particular community. Fieldwork can provide a firsthand understanding of the culture and environment being studied.
• Content analysis: This involves analyzing the content of media from the past, such as films, television programs, and advertisements, to gain insights into cultural attitudes and beliefs.

Data Analysis Methods

• Content analysis : This involves analyzing the content of written or visual material, such as books, newspapers, or photographs, to identify patterns and themes. Content analysis can be used to identify changes in cultural values and beliefs over time.
• Textual analysis : This involves analyzing written texts, such as letters or diaries, to understand the experiences and perspectives of individuals during a particular historical period. Textual analysis can provide insights into how people lived and thought in the past.
• Discourse analysis : This involves analyzing how language is used to construct meaning and power relations in a particular historical period. Discourse analysis can help to identify how social and political ideologies were constructed and maintained over time.
• Statistical analysis: This involves using statistical methods to analyze numerical data, such as census records or economic data, to identify patterns and trends. Statistical analysis can help to identify changes in population demographics, economic conditions, and other factors over time.
• Comparative analysis : This involves comparing data from two or more historical periods or events to identify similarities and differences. Comparative analysis can help to identify patterns and trends that may not be apparent from analyzing data from a single historical period.
• Qualitative analysis: This involves analyzing non-numerical data, such as oral history interviews or ethnographic field notes, to identify themes and patterns. Qualitative analysis can provide a rich understanding of the experiences and perspectives of individuals in the past.

Historical Research Methodology

Here are the general steps involved in historical research methodology:

• Define the research question: Start by identifying a research question that you want to answer through your historical research. This question should be focused, specific, and relevant to your research goals.
• Review the literature: Conduct a review of the existing literature on the topic of your research question. This can involve reading books, articles, and academic papers to gain a thorough understanding of the existing research.
• Develop a research design : Develop a research design that outlines the methods you will use to collect and analyze data. This design should be based on the research question and should be feasible given the resources and time available.
• Collect data: Use the methods outlined in your research design to collect data on past events, people, and cultures. This can involve archival research, oral history interviews, artifact analysis, and other data collection methods.
• Analyze data : Analyze the data you have collected using the methods outlined in your research design. This can involve content analysis, textual analysis, statistical analysis, and other data analysis methods.
• Interpret findings : Use the results of your data analysis to draw meaningful insights and conclusions related to your research question. These insights should be grounded in the data and should be relevant to the research goals.
• Communicate results: Communicate your findings through a research report, academic paper, or other means. This should be done in a clear, concise, and well-organized manner, with appropriate citations and references to the literature.

Applications of Historical Research

Historical research has a wide range of applications in various fields, including:

• Education : Historical research can be used to develop curriculum materials that reflect a more accurate and inclusive representation of history. It can also be used to provide students with a deeper understanding of past events and cultures.
• Museums : Historical research is used to develop exhibits, programs, and other materials for museums. It can provide a more accurate and engaging presentation of historical events and artifacts.
• Public policy : Historical research is used to inform public policy decisions by providing insights into the historical context of current issues. It can also be used to evaluate the effectiveness of past policies and programs.
• Business : Historical research can be used by businesses to understand the evolution of their industry and to identify trends that may affect their future success. It can also be used to develop marketing strategies that resonate with customers’ historical interests and values.
• Law : Historical research is used in legal proceedings to provide evidence and context for cases involving historical events or practices. It can also be used to inform the development of new laws and policies.
• Genealogy : Historical research can be used by individuals to trace their family history and to understand their ancestral roots.
• Cultural preservation : Historical research is used to preserve cultural heritage by documenting and interpreting past events, practices, and traditions. It can also be used to identify and preserve historical landmarks and artifacts.

Examples of Historical Research

Examples of Historical Research are as follows:

• Examining the history of race relations in the United States: Historical research could be used to explore the historical roots of racial inequality and injustice in the United States. This could help inform current efforts to address systemic racism and promote social justice.
• Tracing the evolution of political ideologies: Historical research could be used to study the development of political ideologies over time. This could help to contextualize current political debates and provide insights into the origins and evolution of political beliefs and values.
• Analyzing the impact of technology on society : Historical research could be used to explore the impact of technology on society over time. This could include examining the impact of previous technological revolutions (such as the industrial revolution) on society, as well as studying the current impact of emerging technologies on society and the environment.
• Documenting the history of marginalized communities : Historical research could be used to document the history of marginalized communities (such as LGBTQ+ communities or indigenous communities). This could help to preserve cultural heritage, promote social justice, and promote a more inclusive understanding of history.

Purpose of Historical Research

The purpose of historical research is to study the past in order to gain a better understanding of the present and to inform future decision-making. Some specific purposes of historical research include:

• To understand the origins of current events, practices, and institutions : Historical research can be used to explore the historical roots of current events, practices, and institutions. By understanding how things developed over time, we can gain a better understanding of the present.
• To develop a more accurate and inclusive understanding of history : Historical research can be used to correct inaccuracies and biases in historical narratives. By exploring different perspectives and sources of information, we can develop a more complete and nuanced understanding of history.
• To inform decision-making: Historical research can be used to inform decision-making in various fields, including education, public policy, business, and law. By understanding the historical context of current issues, we can make more informed decisions about how to address them.
• To preserve cultural heritage : Historical research can be used to document and preserve cultural heritage, including traditions, practices, and artifacts. By understanding the historical significance of these cultural elements, we can work to preserve them for future generations.
• To stimulate curiosity and critical thinking: Historical research can be used to stimulate curiosity and critical thinking about the past. By exploring different historical perspectives and interpretations, we can develop a more critical and reflective approach to understanding history and its relevance to the present.

When to use Historical Research

Historical research can be useful in a variety of contexts. Here are some examples of when historical research might be particularly appropriate:

• When examining the historical roots of current events: Historical research can be used to explore the historical roots of current events, practices, and institutions. By understanding how things developed over time, we can gain a better understanding of the present.
• When examining the historical context of a particular topic : Historical research can be used to explore the historical context of a particular topic, such as a social issue, political debate, or scientific development. By understanding the historical context, we can gain a more nuanced understanding of the topic and its significance.
• When exploring the evolution of a particular field or discipline : Historical research can be used to explore the evolution of a particular field or discipline, such as medicine, law, or art. By understanding the historical development of the field, we can gain a better understanding of its current state and future directions.
• When examining the impact of past events on current society : Historical research can be used to examine the impact of past events (such as wars, revolutions, or social movements) on current society. By understanding the historical context and impact of these events, we can gain insights into current social and political issues.
• When studying the cultural heritage of a particular community or group : Historical research can be used to document and preserve the cultural heritage of a particular community or group. By understanding the historical significance of cultural practices, traditions, and artifacts, we can work to preserve them for future generations.

Characteristics of Historical Research

The following are some characteristics of historical research:

• Focus on the past : Historical research focuses on events, people, and phenomena of the past. It seeks to understand how things developed over time and how they relate to current events.
• Reliance on primary sources: Historical research relies on primary sources such as letters, diaries, newspapers, government documents, and other artifacts from the period being studied. These sources provide firsthand accounts of events and can help researchers gain a more accurate understanding of the past.
• Interpretation of data : Historical research involves interpretation of data from primary sources. Researchers analyze and interpret data to draw conclusions about the past.
• Use of multiple sources: Historical research often involves using multiple sources of data to gain a more complete understanding of the past. By examining a range of sources, researchers can cross-reference information and validate their findings.
• Importance of context: Historical research emphasizes the importance of context. Researchers analyze the historical context in which events occurred and consider how that context influenced people’s actions and decisions.
• Subjectivity : Historical research is inherently subjective, as researchers interpret data and draw conclusions based on their own perspectives and biases. Researchers must be aware of their own biases and strive for objectivity in their analysis.
• Importance of historical significance: Historical research emphasizes the importance of historical significance. Researchers consider the historical significance of events, people, and phenomena and their impact on the present and future.
• Use of qualitative methods : Historical research often uses qualitative methods such as content analysis, discourse analysis, and narrative analysis to analyze data and draw conclusions about the past.

Advantages of Historical Research

There are several advantages to historical research:

• Provides a deeper understanding of the past : Historical research can provide a more comprehensive understanding of past events and how they have shaped current social, political, and economic conditions. This can help individuals and organizations make informed decisions about the future.
• Helps preserve cultural heritage: Historical research can be used to document and preserve cultural heritage. By studying the history of a particular culture, researchers can gain insights into the cultural practices and beliefs that have shaped that culture over time.
• Provides insights into long-term trends : Historical research can provide insights into long-term trends and patterns. By studying historical data over time, researchers can identify patterns and trends that may be difficult to discern from short-term data.
• Facilitates the development of hypotheses: Historical research can facilitate the development of hypotheses about how past events have influenced current conditions. These hypotheses can be tested using other research methods, such as experiments or surveys.
• Helps identify root causes of social problems : Historical research can help identify the root causes of social problems. By studying the historical context in which these problems developed, researchers can gain a better understanding of how they emerged and what factors may have contributed to their development.
• Provides a source of inspiration: Historical research can provide a source of inspiration for individuals and organizations seeking to address current social, political, and economic challenges. By studying the accomplishments and struggles of past generations, researchers can gain insights into how to address current challenges.

Limitations of Historical Research

Some Limitations of Historical Research are as follows:

• Reliance on incomplete or biased data: Historical research is often limited by the availability and quality of data. Many primary sources have been lost, destroyed, or are inaccessible, making it difficult to get a complete picture of historical events. Additionally, some primary sources may be biased or represent only one perspective on an event.
• Difficulty in generalizing findings: Historical research is often specific to a particular time and place and may not be easily generalized to other contexts. This makes it difficult to draw broad conclusions about human behavior or social phenomena.
• Lack of control over variables : Historical research often lacks control over variables. Researchers cannot manipulate or control historical events, making it difficult to establish cause-and-effect relationships.
• Subjectivity of interpretation : Historical research is often subjective because researchers must interpret data and draw conclusions based on their own biases and perspectives. Different researchers may interpret the same data differently, leading to different conclusions.
• Limited ability to test hypotheses: Historical research is often limited in its ability to test hypotheses. Because the events being studied have already occurred, researchers cannot manipulate variables or conduct experiments to test their hypotheses.
• Lack of objectivity: Historical research is often subjective, and researchers must be aware of their own biases and strive for objectivity in their analysis. However, it can be difficult to maintain objectivity when studying events that are emotionally charged or controversial.
• Limited generalizability: Historical research is often limited in its generalizability, as the events and conditions being studied may be specific to a particular time and place. This makes it difficult to draw broad conclusions that apply to other contexts or time periods.

• Online Primary Source Collections for History  lists digital collections at Harvard and beyond by topic

Please feel free to email us with questions. We can make an appointment for you to come in, and we can talk at length about your project.

• Anna Assogba ([email protected]) Research Librarian and Liaison to the Department of History, Lamont Library (With particular knowledge of Zotero and other citation management systems).
• Fred Burchsted  ([email protected]) Research Librarian and Liaison to the Department of History, Widener Library.

How can you get your hands/eyes on material?

HOLLIS is the center of the Library ecosystem. This is often the best first step to see if we have something. In HOLLIS, click on "Online Access" or open the record and scroll down to the "Access Options" section. Check the HOLLIS section of this guide for more guidance.

Browser Plugins for Library Access

Harvard Library Bookmark and Lean Library plugins can help you find out if we have access to books and articles online.

Off-Site Storage

Books and other materials stored in facilities not on Harvard's main campus. Request this material through HOLLIS:

• Select "Request Pick Up" in the Access section of the HOLLIS Record, then enter your Harvard Key.
• A drop down menu will allow you to choose delivery location. Sometimes there is a single delivery option. Submit your request.
• You will receive an email usually next business day (not weekends or holidays) morning. Item is usually ready for pick-up in mid-afternoon. 

Sometimes Offsite storage material is in-library use only. For Widener, this is the Widener secure reading room on the 1st floor (formerly the Periodicals Room). Most Offsite storage material is available for scanning via Scan & Deliver (see below). 

Scan & Deliver/Interlibrary Loan

Use Scan & Deliver/Interlibrary Loan to request PDFs of articles and book chapters from HOLLIS when you cannot get online access. Limit: 2 chapters from a book or 2 articles from a journal.

Interlibrary Loan

Request materials from other libraries via InterLibrary Loan :

• Some non-Harvard special collections may be willing and able to scan material (usually for a fee). Our Interlibrary Loan department will place the request and help with the cost (there is a cap).
• Contact the other repository to see if they're able to scan what you need. Get a price estimate for the material and the exact details (such as: Box 77 folder 4. This information is often available in Finding Aids).
• Fill in what you can (put in N/A if the field is inapplicable) with the price and other information in the Comments box.
• This will get the process going and ILL will get back to you if they need more information or to discuss the price.

BorrowDirect

Borrow Direct allows Harvard students, faculty, and staff to request items from other libraries for delivery to Harvard within 4 business days. If the item you need is not available, try searching our partner institutions' collections in BorrowDirect.

Purchase Request

If there are materials you'd like to see added to the library's collections, submit a purchase request and we will look into acquiring it. We can buy both physical and electronic copies of materials; specify if have a preference.

Special Collections

Special Collections are rare, unique, primary source materials in the library's collections. To access, look for "Request to Scan or Visit" in HOLLIS (to place a scanning request) or contact the repository directly. Most of our larger archival collections are able to provide scans.

Carrels at Widener Library

Graduate students and visiting scholars are eligible to have a carrel in the Widener Library stacks. Start the process with the  carrel request form . (If you do this right at the start of the semester, it may take a few weeks before you receive confirmation.) Materials from the Widener stacks, including non-circulating materials like bound periodicals, can be checked out to your carrel.

Ivy Plus Privileges

Our partnership with BorrowDirect allows physical access to libraries of fellow Ivy Plus institutions: Brown University, Columbia University, Cornell University, Dartmouth College, Duke University, Johns Hopkins University, Massachusetts Institute of Technology, Princeton University, Stanford University, University of Chicago, University of Pennsylvania, and Yale University.

Help with Digital Projects

The Digital Scholarship Group offers workshops and support to faculty, students, and staff interested in digital research methods.  See also   GIS Mapping Resources  and  Visualization Support .

Tools and techniques for historical research

• About the Department
• News and events

If you are just starting out in HPS, this will be the first time for many years – perhaps ever – that you have done substantial library or museum based research. The number of general studies may seem overwhelming, yet digging out specific material relevant to your topic may seem like finding needles in a haystack. Before turning to the specific entries that make up this guide, there are a few general points that apply more widely.

Planning your research

Because good research and good writing go hand in hand, probably the single most important key to successful research is having a good topic. For that, all you need at the beginning are two things: (a) a problem that you are genuinely interested in and (b) a specific issue, controversy, technique, instrument, person, etc. that is likely to offer a fruitful way forward for exploring your problem. In the early stages, it's often a good idea to be general about (a) and very specific about (b). So you might be interested in why people decide to become doctors, and decide to look at the early career of a single practitioner from the early nineteenth century, when the evidence for this kind of question happens to be unusually good. You can get lots of advice from people in the Department about places to look for topics, especially if you combine this with reading in areas of potential interest. Remember that you're more likely to get good advice if you're able to mesh your interests with something that a potential supervisor knows about. HPS is such a broad field that it's impossible for any department to cover all aspects of it with an equal degree of expertise. It can be reassuring to know that your topic will evolve as your research develops, although it is vital that you establish some basic parameters relatively quickly. Otherwise you will end up doing the research for two, three or even four research papers or dissertations, when all you need is the material for one.

Before beginning detailed work, it's obviously a good idea to read some of the secondary literature surrounding your subject. The more general books are listed on the reading lists for the Part II lecture courses, and some of the specialist literature is listed in these research guides. This doesn't need to involve an exhaustive search, at least not at this stage, but you do need to master the fundamentals of what's been done if you're going to be in a position to judge the relevance of anything you find. If there are lectures being offered in your topic, make sure to attend them; and if they are offered later in the year, try to see if you can obtain a preliminary bibliography from the lecturer.

After that, it's usually a good idea to immerse yourself in your main primary sources as soon as possible. If you are studying a museum object, this is the time to look at it closely; if you're writing about a debate, get together the main papers relevant to it and give them a close read; if you're writing about a specific experiment, look at the published papers, the laboratory notebook, and the relevant letters. Don't spend hours in the early stages of research ferreting out hard-to-find details, unless you're absolutely positive that they are of central importance to the viability of your topic. Start to get a feel for the material you have, and the questions that might be explored further. Make an outline of the main topics that you hope to cover, organized along what you see as the most interesting themes (and remember, 'background' is not usually an interesting theme on its own).

At this stage, research can go in many different directions. At some point, you'll want to read more about the techniques other historians have used for exploring similar questions. Most fields have an established repertoire of ways of approaching problems, and you need to know what these are, especially if you decide to reject them. One of the advantages of an interdisciplinary field like HPS is that you are exposed to different and often conflicting ways of tackling similar questions. Remember that this is true within history itself, and you need to be aware of alternatives. This may well involve looking further afield, at classic books or articles that are not specifically on 'your' subject. For example, it may be that you could find some helpful ideas for a study of modern scientific portraiture in a book on the eighteenth century. The best books dealing with educational maps may not be on the astronomical ones you are studying, but on ones used for teaching classical geography. See where the inspiration for works you admire comes from, and have a look at the sources they have used. This will help you develop the kind of focussed questions that make for a successful piece of work.

As you develop an outline and begin to think through your topic in more detail, you'll be in good position to plan possible lines of research. Don't try to find out everything about your topic: pick those aspects that are likely to prove most fruitful for the direction your essay seems to be heading. For example, it may be worth spending a long time searching for biographical details about a person if their career and life are central to your analysis; but in many other cases, such issues may not be very important. If your interest is in the reception of a work, it is likely to be more fruitful to learn a lot about a few commentaries or reviews (where they appeared, who wrote them, and so forth) than to gather in randomly all the comments you can find.

Follow up hints in other people's footnotes. Works that are otherwise dull or outdated in approach are sometimes based on very solid research. One secondary reference to a crucial letter or newspaper article can save you hours of mindless trawling, and lead you straight to the information you need. Moreover, good historians often signal questions or sources that they think would be worth investigating further.

Remember that the best history almost always depends on developing new approaches and interpretations, not on knowing about a secret archive no one has used before. If you give your work time to develop, and combine research with writing, you will discover new sources, and (better still) a fresh importance for material that has supposedly been known for a long time. As you become familiar with your topic, you are likely to find that evidence you dug out at the beginning of your project is much more significant than you thought it was. In historical research, the most important evidence often isn't sitting there on the surface – it's something you need to dig out through close reading and an understanding of the situation in which the document you are studying was written, or in which the object was produced. This is especially true of instruments, paintings and other non-textual sources.

Some standard reference works

Your research should become more focussed as time goes on. Don't just gather randomly: you should always have at least some idea of why you are looking for something, and what you might hope to find. Make guesses, follow up hunches, see if an idea you have has the possibility to work out. At the beginning, it can be valuable to learn the full range of what is available, but eventually you should be following up specific issues, a bit like a detective tracing the clues to a mystery. It is at this stage of research, which is often best done in conjunction with writing up sections of your project, that knowing where to find answers to specific questions is most useful. There is nothing more disheartening than spending a week to find a crucial fact, only to discover that it's been sitting on the shelf next to you all term. The Whipple has a wide variety of guides, biographical dictionaries and bibliographies, so spend a few minutes early on looking at the reference shelves.

Every major country has a national biographical dictionary (the new version of the British one is the Oxford Dictionary of National Biography , available 2004 online). For better-known scientists, a good place to start is Charles C. Gillispie (ed.) Dictionary of Scientific Biography (1970–1980). There are more specialized dictionaries for every scientific field, from entomology to astronomy. The University Library has a huge selection of biographical sources; ask your supervisor about the best ones for your purpose.

Preliminary searching for book titles and other bibliographical information is now often best done online, and every historian should know how to use the British Library's online search facility; COPAC (the UK national library database); and WorldCat (an international database). All of these are accessible through the HPS Whipple Library website (under 'other catalogues'). At the time of writing, the University Library is remains one of the few libraries of its size to have many of its records not available online, so remember that you have to check the green guard-book catalogues (and the supplementary catalogues) for most items published before 1977. It is hoped that this situation will be rectified soon. There are also numerous bibliographies for individual sciences and subjects, together with catalogues of relevant manuscripts. Most of these are listed elsewhere in this guide.

As questions arise, you will want to be able to access books and articles by other historians that touch upon your subject. There are many sources for this listed elsewhere in this guide, but you should definitely know about the Isis Current Bibliography and The Wellcome Bibliography for the History of Medicine . Both are available online, the former through the RLG History of Science, Technology and Medicine database, the latter through the website of the Wellcome Library.

Libraries and museums

Finally, a word in praise of libraries and museums. As the comments above make clear, the internet is invaluable for searching for specific pieces of information. If you need a bibliographical reference or a general reading list from a course at another university, it is an excellent place to begin. If you are looking for the source of an unidentified quotation, typing it into Google (or an appropriate database held by the University Library) will often turn up the source in seconds. Many academic journals are now online, as are the texts of many books, though not always in a paginated or citable form.

For almost all historical topics, however, libraries filled with printed books and journals will remain the principal tools for research, just as museums will continue to be essential to any work dealing with the material culture of past science. The reason for this is simple: what is on the internet is the result of decisions by people in the past decade, while libraries and museums are the product of a continuous history of collecting over several thousand years. Cambridge has some of the best collections for the history of science anywhere. Despite what is often said, this is not because of the famous manuscripts or showpiece books (these are mostly available in other ways), but because of the depth and range of its collections across the whole field. The Whipple Library is small and friendly, and has an unparalleled selection of secondary works selected over many years – don't just go for specific titles you've found in the catalogue, try browsing around, and ask the librarians for help if you can't see what you are looking for. Explore the Whipple Museum and talk to the curator and the staff. There are rich troves of material in these departmental collections, on topics ranging from phrenology and microscopy to the early development of pocket calculators. Become familiar with what the University Library has to offer: it is large and sometimes idiosyncratic, but worth getting to know well if you are at all serious about research. It is a fantastic instrument for studying the human past – the historian's equivalent of CERN or the Hubble Telescope. And all you need to get in is a student ID.

Historical studies lays the foundation for all social inquiry and for informed debate on the politics and culture of our time. Bridging the humanities with the social sciences, our innovative program trains students in conceptual rigor, archival research, critical analysis, and historical writing. Our strong links to other New School for Social Research departments and to centers and programs across The New School provide our students with unparalleled opportunities for engagement with critical social theory and in interdisciplinary collaboration.

Founded in the mid-1980s by Charles Tilly, Louise Tilly, Aristide Zolberg, and Ira Katznelson, the Committee for Historical Studies continues to build upon its original premise: that history is a field of inquiry critical to all human understanding. We remain committed to developing theoretically informed and critical approaches to historical questions.

Our course offerings cover a wide range of historical periods and world regions, with particular strength in the large-scale transformations of the modern era. Areas of faculty expertise include the history of capitalism, history of politics, history of violence, gender history, history of psychoanalysis, history of social movements, and history and theory. Our diverse approaches draw on the insights of critical social theory. Committed faculty mentors work with students to cultivate their abilities as scholars, as educators, and as writers who can communicate to a wide audience. We offer an MA degree as well as a specialized minor for NSSR PhD students only.

Outside of our department, students pursuing a degree in Historical Studies take part in the intellectual life of NSSR's many centers , including the Robert L. Heilbroner Center for Capitalism Studies , and the Zolberg Center on Migration and Mobility . Students contribute to our online publication, Public Seminar , and engage with New York City's peerless array of scholarly and cultural institutions.

Our alumni pursue doctoral study at The New School for Social Research and other top universities or put their training to use successfully in a wide range of non-academic careers.

Historical Studies is available as the MA degree only. Students who complete the requirements for the MA in Historical Studies and wish to earn a PhD degree can apply for admission to NSSR's PhD in Politics or Sociology with a minor in Historical Studies.

A Step-by-Step Guide to Doing Historical Research [without getting hysterical!] In addition to being a scholarly investigation, research is a social activity intended to create new knowledge. Historical research is your informed response to the questions that you ask while examining the record of human experience. These questions may concern such elements as looking at an event or topic, examining events that lead to the event in question, social influences, key players, and other contextual information. This step-by-step guide progresses from an introduction to historical resources to information about how to identify a topic, craft a thesis and develop a research paper. Table of contents: The Range and Richness of Historical Sources Secondary Sources Primary Sources Historical Analysis What is it? Who, When, Where, What and Why: The Five "W"s Topic, Thesis, Sources Definition of Terms Choose a Topic Craft a Thesis Evaluate Thesis and Sources A Variety of Information Sources Take Efficient Notes Note Cards Thinking, Organizing, Researching Parenthetical Documentation Prepare a Works Cited Page Drafting, Revising, Rewriting, Rethinking For Further Reading: Works Cited Additional Links So you want to study history?! Tons of help and links Slatta Home Page Use the Writing and other links on the lefhand menu I. The Range and Richness of Historical Sources Back to Top Every period leaves traces, what historians call "sources" or evidence. Some are more credible or carry more weight than others; judging the differences is a vital skill developed by good historians. Sources vary in perspective, so knowing who created the information you are examining is vital. Anonymous doesn't make for a very compelling source. For example, an FBI report on the antiwar movement, prepared for U.S. President Richard Nixon, probably contained secrets that at the time were thought to have affected national security. It would not be usual, however, for a journalist's article about a campus riot, featured in a local newspaper, to leak top secret information. Which source would you read? It depends on your research topic. If you're studying how government officials portrayed student activists, you'll want to read the FBI report and many more documents from other government agencies such as the CIA and the National Security Council. If you're investigating contemporary opinion of pro-war and anti-war activists, local newspaper accounts provide a rich resource. You'd want to read a variety of newspapers to ensure you're covering a wide range of opinions (rural/urban, left/right, North/South, Soldier/Draft-dodger, etc). Historians classify sources into two major categories: primary and secondary sources. Secondary Sources Back to Top Definition: Secondary sources are created by someone who was either not present when the event occurred or removed from it in time. We use secondary sources for overview information, to familiarize ourselves with a topic, and compare that topic with other events in history. In refining a research topic, we often begin with secondary sources. This helps us identify gaps or conflicts in the existing scholarly literature that might prove promsing topics. Types: History books, encyclopedias, historical dictionaries, and academic (scholarly) articles are secondary sources. To help you determine the status of a given secondary source, see How to identify and nagivate scholarly literature . Examples: Historian Marilyn Young's (NYU) book about the Vietnam War is a secondary source. She did not participate in the war. Her study is not based on her personal experience but on the evidence she culled from a variety of sources she found in the United States and Vietnam. Primary Sources Back to Top Definition: Primary sources emanate from individuals or groups who participated in or witnessed an event and recorded that event during or immediately after the event. They include speeches, memoirs, diaries, letters, telegrams, emails, proclamations, government documents, and much more. Examples: A student activist during the war writing about protest activities has created a memoir. This would be a primary source because the information is based on her own involvement in the events she describes. Similarly, an antiwar speech is a primary source. So is the arrest record of student protesters. A newspaper editorial or article, reporting on a student demonstration is also a primary source. II. Historical Analysis What is it? Back to Top No matter what you read, whether it's a primary source or a secondary source, you want to know who authored the source (a trusted scholar? A controversial historian? A propagandist? A famous person? An ordinary individual?). "Author" refers to anyone who created information in any medium (film, sound, or text). You also need to know when it was written and the kind of audience the author intend to reach. You should also consider what you bring to the evidence that you examine. Are you inductively following a path of evidence, developing your interpretation based on the sources? Do you have an ax to grind? Did you begin your research deductively, with your mind made up before even seeing the evidence. Historians need to avoid the latter and emulate the former. To read more about the distinction, examine the difference between Intellectual Inquirers and Partisan Ideologues . In the study of history, perspective is everything. A letter written by a twenty- year old Vietnam War protestor will differ greatly from a letter written by a scholar of protest movements. Although the sentiment might be the same, the perspective and influences of these two authors will be worlds apart. Practicing the " 5 Ws " will avoid the confusion of the authority trap. Who, When, Where, What and Why: The Five "W"s Back to Top Historians accumulate evidence (information, including facts, stories, interpretations, opinions, statements, reports, etc.) from a variety of sources (primary and secondary). They must also verify that certain key pieces of information are corroborated by a number of people and sources ("the predonderance of evidence"). The historian poses the " 5 Ws " to every piece of information he examines: Who is the historical actor? When did the event take place? Where did it occur? What did it entail and why did it happen the way it did? The " 5 Ws " can also be used to evaluate a primary source. Who authored the work? When was it created? Where was it created, published, and disseminated? Why was it written (the intended audience), and what is the document about (what points is the author making)? If you know the answers to these five questions, you can analyze any document, and any primary source. The historian doesn't look for the truth, since this presumes there is only one true story. The historian tries to understand a number of competing viewpoints to form his or her own interpretation-- what constitutes the best explanation of what happened and why. By using as wide a range of primary source documents and secondary sources as possible, you will add depth and richness to your historical analysis. The more exposure you, the researcher, have to a number of different sources and differing view points, the more you have a balanced and complete view about a topic in history. This view will spark more questions and ultimately lead you into the quest to unravel more clues about your topic. You are ready to start assembling information for your research paper. III. Topic, Thesis, Sources Definition of Terms Back to Top Because your purpose is to create new knowledge while recognizing those scholars whose existing work has helped you in this pursuit, you are honor bound never to commit the following academic sins: Plagiarism: Literally "kidnapping," involving the use of someone else's words as if they were your own (Gibaldi 6). To avoid plagiarism you must document direct quotations, paraphrases, and original ideas not your own. Recycling: Rehashing material you already know thoroughly or, without your professor's permission, submitting a paper that you have completed for another course. Premature cognitive commitment: Academic jargon for deciding on a thesis too soon and then seeking information to serve that thesis rather than embarking on a genuine search for new knowledge. Choose a Topic Back to Top "Do not hunt for subjects, let them choose you, not you them." --Samuel Butler Choosing a topic is the first step in the pursuit of a thesis. Below is a logical progression from topic to thesis: Close reading of the primary text, aided by secondary sources Growing awareness of interesting qualities within the primary text Choosing a topic for research Asking productive questions that help explore and evaluate a topic Creating a research hypothesis Revising and refining a hypothesis to form a working thesis First, and most important, identify what qualities in the primary or secondary source pique your imagination and curiosity and send you on a search for answers. Bloom's taxonomy of cognitive levels provides a description of productive questions asked by critical thinkers. While the lower levels (knowledge, comprehension) are necessary to a good history essay, aspire to the upper three levels (analysis, synthesis, evaluation). Skimming reference works such as encyclopedias, books, critical essays and periodical articles can help you choose a topic that evolves into a hypothesis, which in turn may lead to a thesis. One approach to skimming involves reading the first paragraph of a secondary source to locate and evaluate the author's thesis. Then for a general idea of the work's organization and major ideas read the first and last sentence of each paragraph. Read the conclusion carefully, as it usually presents a summary (Barnet and Bedau 19). Craft a Thesis Back to Top Very often a chosen topic is too broad for focused research. You must revise it until you have a working hypothesis, that is, a statement of an idea or an approach with respect to the source that could form the basis for your thesis. Remember to not commit too soon to any one hypothesis. Use it as a divining rod or a first step that will take you to new information that may inspire you to revise your hypothesis. Be flexible. Give yourself time to explore possibilities. The hypothesis you create will mature and shift as you write and rewrite your paper. New questions will send you back to old and on to new material. Remember, this is the nature of research--it is more a spiraling or iterative activity than a linear one. Test your working hypothesis to be sure it is: broad enough to promise a variety of resources. narrow enough for you to research in depth. original enough to interest you and your readers. worthwhile enough to offer information and insights of substance "do-able"--sources are available to complete the research. Now it is time to craft your thesis, your revised and refined hypothesis. A thesis is a declarative sentence that: focuses on one well-defined idea makes an arguable assertion; it is capable of being supported prepares your readers for the body of your paper and foreshadows the conclusion. Evaluate Thesis and Sources Back to Top Like your hypothesis, your thesis is not carved in stone. You are in charge. If necessary, revise it during the research process. As you research, continue to evaluate both your thesis for practicality, originality, and promise as a search tool, and secondary sources for relevance and scholarliness. The following are questions to ask during the research process: Are there many journal articles and entire books devoted to the thesis, suggesting that the subject has been covered so thoroughly that there may be nothing new to say? Does the thesis lead to stimulating, new insights? Are appropriate sources available? Is there a variety of sources available so that the bibliography or works cited page will reflect different kinds of sources? Which sources are too broad for my thesis? Which resources are too narrow? Who is the author of the secondary source? Does the critic's background suggest that he/she is qualified? After crafting a thesis, consider one of the following two approaches to writing a research paper: Excited about your thesis and eager to begin? Return to the primary or secondary source to find support for your thesis. Organize ideas and begin writing your first draft. After writing the first draft, have it reviewed by your peers and your instructor. Ponder their suggestions and return to the sources to answer still-open questions. Document facts and opinions from secondary sources. Remember, secondary sources can never substitute for primary sources. Confused about where to start? Use your thesis to guide you to primary and secondary sources. Secondary sources can help you clarify your position and find a direction for your paper. Keep a working bibliography. You may not use all the sources you record, but you cannot be sure which ones you will eventually discard. Create a working outline as you research. This outline will, of course, change as you delve more deeply into your subject. A Variety of Information Sources Back to Top "A mind that is stretched to a new idea never returns to its original dimension." --Oliver Wendell Holmes Your thesis and your working outline are the primary compasses that will help you navigate the variety of sources available. In "Introduction to the Library" (5-6) the MLA Handbook for Writers of Research Papers suggests you become familiar with the library you will be using by: taking a tour or enrolling for a brief introductory lecture referring to the library's publications describing its resources introducing yourself and your project to the reference librarian The MLA Handbook also lists guides for the use of libraries (5), including: Jean Key Gates, Guide to the Use of Libraries and Information Sources (7th ed., New York: McGraw, 1994). Thomas Mann, A Guide to Library Research Methods (New York: Oxford UP, 1987). Online Central Catalog Most libraries have their holdings listed on a computer. The online catalog may offer Internet sites, Web pages and databases that relate to the university's curriculum. It may also include academic journals and online reference books. Below are three search techniques commonly used online: Index Search: Although online catalogs may differ slightly from library to library, the most common listings are by: Subject Search: Enter the author's name for books and article written about the author. Author Search: Enter an author's name for works written by the author, including collections of essays the author may have written about his/her own works. Title Search: Enter a title for the screen to list all the books the library carries with that title. Key Word Search/Full-text Search: A one-word search, e.g., 'Kennedy,' will produce an overwhelming number of sources, as it will call up any entry that includes the name 'Kennedy.' To focus more narrowly on your subject, add one or more key words, e.g., "John Kennedy, Peace Corps." Use precise key words. Boolean Search: Boolean Search techniques use words such as "and," "or," and "not," which clarify the relationship between key words, thus narrowing the search. Take Efficient Notes Back to Top Keeping complete and accurate bibliography and note cards during the research process is a time (and sanity) saving practice. If you have ever needed a book or pages within a book, only to discover that an earlier researcher has failed to return it or torn pages from your source, you understand the need to take good notes. Every researcher has a favorite method for taking notes. Here are some suggestions-- customize one of them for your own use. Bibliography cards There may be far more books and articles listed than you have time to read, so be selective when choosing a reference. Take information from works that clearly relate to your thesis, remembering that you may not use them all. Use a smaller or a different color card from the one used for taking notes. Write a bibliography card for every source. Number the bibliography cards. On the note cards, use the number rather than the author's name and the title. It's faster. Another method for recording a working bibliography, of course, is to create your own database. Adding, removing, and alphabetizing titles is a simple process. Be sure to save often and to create a back-up file. A bibliography card should include all the information a reader needs to locate that particular source for further study. Most of the information required for a book entry (Gibaldi 112): Author's name Title of a part of the book [preface, chapter titles, etc.] Title of the book Name of the editor, translator, or compiler Edition used Number(s) of the volume(s) used Name of the series Place of publication, name of the publisher, and date of publication Page numbers Supplementary bibliographic information and annotations Most of the information required for an article in a periodical (Gibaldi 141): Author's name Title of the article Name of the periodical Series number or name (if relevant) Volume number (for a scholarly journal) Issue number (if needed) Date of publication Page numbers Supplementary information For information on how to cite other sources refer to your So you want to study history page . Note Cards Back to Top Take notes in ink on either uniform note cards (3x5, 4x6, etc.) or uniform slips of paper. Devote each note card to a single topic identified at the top. Write only on one side. Later, you may want to use the back to add notes or personal observations. Include a topical heading for each card. Include the number of the page(s) where you found the information. You will want the page number(s) later for documentation, and you may also want page number(s)to verify your notes. Most novice researchers write down too much. Condense. Abbreviate. You are striving for substance, not quantity. Quote directly from primary sources--but the "meat," not everything. Suggestions for condensing information: Summary: A summary is intended to provide the gist of an essay. Do not weave in the author's choice phrases. Read the information first and then condense the main points in your own words. This practice will help you avoid the copying that leads to plagiarism. Summarizing also helps you both analyze the text you are reading and evaluate its strengths and weaknesses (Barnet and Bedau 13). Outline: Use to identify a series of points. Paraphrase, except for key primary source quotations. Never quote directly from a secondary source, unless the precise wording is essential to your argument. Simplify the language and list the ideas in the same order. A paraphrase is as long as the original. Paraphrasing is helpful when you are struggling with a particularly difficult passage. Be sure to jot down your own insights or flashes of brilliance. Ralph Waldo Emerson warns you to "Look sharply after your thoughts. They come unlooked for, like a new bird seen on your trees, and, if you turn to your usual task, disappear...." To differentiate these insights from those of the source you are reading, initial them as your own. (When the following examples of note cards include the researcher's insights, they will be followed by the initials N. R.) When you have finished researching your thesis and you are ready to write your paper, organize your cards according to topic. Notecards make it easy to shuffle and organize your source information on a table-- or across the floor. Maintain your working outline that includes the note card headings and explores a logical order for presenting them in your paper. IV. Begin Thinking, Researching, Organizing Back to Top Don't be too sequential. Researching, writing, revising is a complex interactive process. Start writing as soon as possible! "The best antidote to writer's block is--to write." (Klauser 15). However, you still feel overwhelmed and are staring at a blank page, you are not alone. Many students find writing the first sentence to be the most daunting part of the entire research process. Be creative. Cluster (Rico 28-49). Clustering is a form of brainstorming. Sometimes called a web, the cluster forms a design that may suggest a natural organization for a paper. Here's a graphical depiction of brainstorming . Like a sun, the generating idea or topic lies at the center of the web. From it radiate words, phrases, sentences and images that in turn attract other words, phrases, sentences and images. Put another way--stay focused. Start with your outline. If clustering is not a technique that works for you, turn to the working outline you created during the research process. Use the outline view of your word processor. If you have not already done so, group your note cards according to topic headings. Compare them to your outline's major points. If necessary, change the outline to correspond with the headings on the note cards. If any area seems weak because of a scarcity of facts or opinions, return to your primary and/or secondary sources for more information or consider deleting that heading. Use your outline to provide balance in your essay. Each major topic should have approximately the same amount of information. Once you have written a working outline, consider two different methods for organizing it. Deduction: A process of development that moves from the general to the specific. You may use this approach to present your findings. However, as noted above, your research and interpretive process should be inductive. Deduction is the most commonly used form of organization for a research paper. The thesis statement is the generalization that leads to the specific support provided by primary and secondary sources. The thesis is stated early in the paper. The body of the paper then proceeds to provide the facts, examples, and analogies that flow logically from that thesis. The thesis contains key words that are reflected in the outline. These key words become a unifying element throughout the paper, as they reappear in the detailed paragraphs that support and develop the thesis. The conclusion of the paper circles back to the thesis, which is now far more meaningful because of the deductive development that supports it. Chronological order A process that follows a traditional time line or sequence of events. A chronological organization is useful for a paper that explores cause and effect. Parenthetical Documentation Back to Top The Works Cited page, a list of primary and secondary sources, is not sufficient documentation to acknowledge the ideas, facts, and opinions you have included within your text. The MLA Handbook for Writers of Research Papers describes an efficient parenthetical style of documentation to be used within the body of your paper. Guidelines for parenthetical documentation: "References to the text must clearly point to specific sources in the list of works cited" (Gibaldi 184). Try to use parenthetical documentation as little as possible. For example, when you cite an entire work, it is preferable to include the author's name in the text. The author's last name followed by the page number is usually enough for an accurate identification of the source in the works cited list. These examples illustrate the most common kinds of documentation. Documenting a quotation: Ex. "The separation from the personal mother is a particularly intense process for a daughter because she has to separate from the one who is the same as herself" (Murdock 17). She may feel abandoned and angry. Note: The author of The Heroine's Journey is listed under Works Cited by the author's name, reversed--Murdock, Maureen. Quoted material is found on page 17 of that book. Parenthetical documentation is after the quotation mark and before the period. Documenting a paraphrase: Ex. In fairy tales a woman who holds the princess captive or who abandons her often needs to be killed (18). Note: The second paraphrase is also from Murdock's book The Heroine's Journey. It is not, however, necessary to repeat the author's name if no other documentation interrupts the two. If the works cited page lists more than one work by the same author, include within the parentheses an abbreviated form of the appropriate title. You may, of course, include the title in your sentence, making it unnecessary to add an abbreviated title in the citation. > Prepare a Works Cited Page Back to Top There are a variety of titles for the page that lists primary and secondary sources (Gibaldi 106-107). A Works Cited page lists those works you have cited within the body of your paper. The reader need only refer to it for the necessary information required for further independent research. Bibliography means literally a description of books. Because your research may involve the use of periodicals, films, art works, photographs, etc. "Works Cited" is a more precise descriptive term than bibliography. An Annotated Bibliography or Annotated Works Cited page offers brief critiques and descriptions of the works listed. A Works Consulted page lists those works you have used but not cited. Avoid using this format. As with other elements of a research paper there are specific guidelines for the placement and the appearance of the Works Cited page. The following guidelines comply with MLA style: The Work Cited page is placed at the end of your paper and numbered consecutively with the body of your paper. Center the title and place it one inch from the top of your page. Do not quote or underline the title. Double space the entire page, both within and between entries. The entries are arranged alphabetically by the author's last name or by the title of the article or book being cited. If the title begins with an article (a, an, the) alphabetize by the next word. If you cite two or more works by the same author, list the titles in alphabetical order. Begin every entry after the first with three hyphens followed by a period. All entries begin at the left margin but subsequent lines are indented five spaces. Be sure that each entry cited on the Works Cited page corresponds to a specific citation within your paper. Refer to the the MLA Handbook for Writers of Research Papers (104- 182) for detailed descriptions of Work Cited entries. Citing sources from online databases is a relatively new phenomenon. Make sure to ask your professor about citing these sources and which style to use. V. Draft, Revise, Rewrite, Rethink Back to Top "There are days when the result is so bad that no fewer than five revisions are required. In contrast, when I'm greatly inspired, only four revisions are needed." --John Kenneth Galbraith Try freewriting your first draft. Freewriting is a discovery process during which the writer freely explores a topic. Let your creative juices flow. In Writing without Teachers , Peter Elbow asserts that "[a]lmost everybody interposes a massive and complicated series of editings between the time words start to be born into consciousness and when they finally come off the end of the pencil or typewriter [or word processor] onto the page" (5). Do not let your internal judge interfere with this first draft. Creating and revising are two very different functions. Don't confuse them! If you stop to check spelling, punctuation, or grammar, you disrupt the flow of creative energy. Create; then fix it later. When material you have researched comes easily to mind, include it. Add a quick citation, one you can come back to later to check for form, and get on with your discovery. In subsequent drafts, focus on creating an essay that flows smoothly, supports fully, and speaks clearly and interestingly. Add style to substance. Create a smooth flow of words, ideas and paragraphs. Rearrange paragraphs for a logical progression of information. Transition is essential if you want your reader to follow you smoothly from introduction to conclusion. Transitional words and phrases stitch your ideas together; they provide coherence within the essay. External transition: Words and phrases that are added to a sentence as overt signs of transition are obvious and effective, but should not be overused, as they may draw attention to themselves and away from ideas. Examples of external transition are "however," "then," "next," "therefore." "first," "moreover," and "on the other hand." Internal transition is more subtle. Key words in the introduction become golden threads when they appear in the paper's body and conclusion. When the writer hears a key word repeated too often, however, she/he replaces it with a synonym or a pronoun. Below are examples of internal transition. Transitional sentences create a logical flow from paragraph to paragraph. Iclude individual words, phrases, or clauses that refer to previous ideas and that point ahead to new ones. They are usually placed at the end or at the beginning of a paragraph. A transitional paragraph conducts your reader from one part of the paper to another. It may be only a few sentences long. Each paragraph of the body of the paper should contain adequate support for its one governing idea. Speak/write clearly, in your own voice. Tone: The paper's tone, whether formal, ironic, or humorous, should be appropriate for the audience and the subject. Voice: Keep you language honest. Your paper should sound like you. Understand, paraphrase, absorb, and express in your own words the information you have researched. Avoid phony language. Sentence formation: When you polish your sentences, read them aloud for word choice and word placement. Be concise. Strunk and White in The Elements of Style advise the writer to "omit needless words" (23). First, however, you must recognize them. Keep yourself and your reader interested. In fact, Strunk's 1918 writing advice is still well worth pondering. First, deliver on your promises. Be sure the body of your paper fulfills the promise of the introduction. Avoid the obvious. Offer new insights. Reveal the unexpected. Have you crafted your conclusion as carefully as you have your introduction? Conclusions are not merely the repetition of your thesis. The conclusion of a research paper is a synthesis of the information presented in the body. Your research has led you to conclusions and opinions that have helped you understand your thesis more deeply and more clearly. Lift your reader to the full level of understanding that you have achieved. Revision means "to look again." Find a peer reader to read your paper with you present. Or, visit your college or university's writing lab. Guide your reader's responses by asking specific questions. Are you unsure of the logical order of your paragraphs? Do you want to know whether you have supported all opinions adequately? Are you concerned about punctuation or grammar? Ask that these issues be addressed. You are in charge. Here are some techniques that may prove helpful when you are revising alone or with a reader. When you edit for spelling errors read the sentences backwards. This procedure will help you look closely at individual words. Always read your paper aloud. Hearing your own words puts them in a new light. Listen to the flow of ideas and of language. Decide whether or not the voice sounds honest and the tone is appropriate to the purpose of the paper and to your audience. Listen for awkward or lumpy wording. Find the one right word, Eliminate needless words. Combine sentences. Kill the passive voice. Eliminate was/were/is/are constructions. They're lame and anti-historical. Be ruthless. If an idea doesn't serve your thesis, banish it, even if it's one of your favorite bits of prose. In the margins, write the major topic of each paragraph. By outlining after you have written the paper, you are once again evaluating your paper's organization. OK, you've got the process down. Now execute! And enjoy! It's not everyday that you get to make history. VI. For Further Reading: Works Cited Back to Top Barnet, Sylvan, and Hugo Bedau. Critical Thinking, Reading, and Writing: A Brief Guide to Argument.

Historical Research Process

Historical Research often involves these steps

• Identify a topic or research question
• Conduct background research on the topic or question
• Refine or narrow research topic or question based on background research
• Identify primary and secondary sources
• Evaluate the sources for relevancy, authenticity, and accuracy. 
• Analyze sources and form an argument based on information gathered 

It should be noted that the research process is rarely linear. Many of these steps may occur multiple times throughout the research process. This is normal. 

(Berg & Lune, 2012, 311 and  https://ecu.au.libguides.com/historical-research-method ) 

Primary Sources

Historical Research depends heavily on both Primary and Secondary sources

Primary sources are contemporary to the time period in which they were created. These sources can give researchers insight into various aspects of the time period in question and can be analyzed in a variety of ways depending on the research goal. 

Examples of Primary Sources include but are not limited to the following:

• Eyewitness accounts of events
• Newspapers from the time period
• Personal papers
• Legal documents
• Public records
• Contemporary works of literature

You typically find primary sources in archives. Archives can be associated with a larger organization such as a library, university, or government entity. They can also be independently run. 

Secondary Sources

Secondary sources are resources that are developed through an evaluation of primary source evidence. These can be scholarly or for general consumption. 

Examples of Secondary Sources include but are not limited to the following: 

• Encyclopedias
• Journal articles
• Biographies
• Documentaries

Secondary sources are typically found among library resources.

Historical Research – A Guide Based on its Uses & Steps

Published by Alvin Nicolas at August 16th, 2021 , Revised On August 29, 2023

History is a study of past incidents, and it’s different from natural science. In natural science, researchers prefer direct observations. Whereas in historical research, a researcher collects, analyses the information to understand, describe, and explain the events that occurred in the past.

They aim to test the truthfulness of the observations made by others. Historical researchers try to find out what happened exactly during a certain period of time as accurately and as closely as possible. It does not allow any manipulation or control of  variables .

When to Use the Historical Research Method?

You can use historical research method to:

• Uncover the unknown fact.
• Answer questions
• Identify the association between the past and present.
• Understand the culture based on past experiences..
• Record and evaluate the contributions of individuals, organisations, and institutes.

How to Conduct Historical Research?

Historical research involves the following steps:

• Select the Research Topic
• Collect the Data
• Analyse the Data
• Criticism of Data
• Present your Findings

Tips to Collect Data

Step 1 – select the research topic.

If you want to conduct historical research, it’s essential to select a research topic before beginning your research. You can follow these tips while choosing a topic and  developing a research question .

• Consider your previous study as your previous knowledge and data can make your research enjoyable and comfortable for you.
• List your interests and focus on the current events to find a promising question.
• Take notes of regular activities and consider your personal experiences on a specific topic.
• Develop a question using your research topic.
• Explore your research question by asking yourself when? Why? How

Step 2- Collect the Data

It is essential to collect data and facts about the research question to get reliable outcomes. You need to select an appropriate instrument for  data collection . Historical research includes two sources of data collection, such as primary and secondary sources.

Primary Sources

Primary sources  are the original first-hand resources such as documents, oral or written records, witnesses to a fact, etc. These are of two types, such as:

Conscious Information : It’s a type of information recorded and restored consciously in the form of written, oral documents, or the actual witnesses of the incident that occurred in the past.

It includes the following sources:

Unconscious information : It’s a type of information restored in the form of remains or relics.

It includes information in the following forms:

Secondary Sources

Sometimes it’s impossible to access primary sources, and researchers rely on secondary sources to obtain information for their research. 

It includes:

• Publications
• Periodicals
• Encyclopedia

Step 3 – Analyse the Data

After collecting the information, you need to analyse it. You can use data analysis methods  like 

• Thematic analysis
• Coding system
• Theoretical model ( Researchers use multiple theories to explain a specific phenomenon, situations, and behavior types.)
• Quantitative data to validate

Step 4 – Criticism of Data

Data criticism is a process used for identifying the validity and reliability of the collected data. It’s of two types such as:

External Criticism :

It aims at identifying the external features of the data such as signature, handwriting, language, nature, spelling, etc., of the documents. It also involves the physical and chemical tests of paper, paint, ink, metal cloth, or any collected object.

Internal Criticism :

It aims at identifying the meaning and reliability of the data. It focuses on the errors, printing, translation, omission, additions in the documents. The researchers should use both external and internal criticism to ensure the validity of the data.

Step 5 – Present your Findings

While presenting the  findings of your research , you need to ensure that you have met the objectives of your research or not. Historical material can be organised based on the theme and topic, and it’s known as thematic and topical arrangement. You can follow these tips while writing your research paper :

Build Arguments and Narrative

Your research aims not just to collect information as these are the raw materials of research. You need to build a strong argument and narrate the details of past events or incidents based on your findings. 

Organise your Argument

You can review the literature and other researchers’ contributions to the topic you’ve chosen to enhance your thinking and argument.

Proofread, Revise and Edit

After putting your findings on a paper, you need to proofread it to weed out the errors, rewrite it to improve, and edit it thoroughly before submitting it.

In this world of technology, many people rely on Google to find out any information. All you have to do is enter a few keywords and sit back. You’ll find several relevant results onscreen.

It’s an effective and quick way of gathering information. Sometimes historical documents are not accessible to everyone online, and you need to visit traditional libraries to find out historical treasures. It will help you explore your knowledge along with data collection. 

You can visit historical places, conduct interviews, review literature, and access  primary and secondary  data sources such as books, newspapers, publications, documents, etc. You can take notes while collecting the information as it helps to organise the data accurately.

How to Do Historical Research: 5 Tips for Studying History

Written by MasterClass

Last updated: Jun 7, 2021 • 3 min read

A popular aphorism declares that "those who do not study history are doomed to repeat it." Humans study history in part because social behaviors and global trends repeat themselves over time. If we understand how to study history, we can orient ourselves toward a future of progress rather than repeated mistakes.

How Institutions Use Historical Research Methods to Provide Historical Perspectives

An Overview of Historical Research Methods

Historical research methods enable institutions to collect facts, chronological data, and other information relevant to their interests. But historical research is more than compiling a record of past events; it provides institutions with valuable insights about the past to inform current cultural, political, and social dynamics.

Historical research methods primarily involve collecting information from primary and secondary sources. While differences exist between these sources, organizations and institutions can use both types of sources to assess historical events and provide proper context comprehensively.

Using historical research methods, historians provide institutions with historical insights that can give perspectives on the future.

Individuals interested in advancing their careers as historians can pursue an advanced degree, such as a Master of Arts in History , to help them develop a systematic understanding of historical research and learn about the use of digital tools for acquiring, accessing, and managing historical information.

Historians use historical research methods to obtain data from primary and secondary sources and, then, assess how the information contributes to understanding a historical period or event. Historical research methods are used with primary and secondary sources. Below is a description of each type of source.

What Is a Primary Source?              

Primary sources—raw data containing first-person accounts and documents—are foundational to historical and academic research. Examples of primary sources include eyewitness accounts of historical events, written testimonies, public records, oral representations, legal documents, artifacts, photographs, art, newspaper articles, diaries, and letters. Individuals often can find primary sources in archives and collections in universities, libraries, and historical societies.

A primary source, also known as primary data, is often characterized by the time of its creation. For example, individuals studying the U.S. Constitution’s beginnings can use The Federalist Papers, a collection of essays by Alexander Hamilton, John Jay, and James Madison, written from October 1787 to May 1788, as a primary source for their research. In this example, the information was witnessed firsthand and created at the time of the event.

What Is a Secondary Source?              

Primary sources are not always easy to find. In the absence of primary sources, secondary sources can play a vital role in describing historical events. A historian can create a secondary source by analyzing, synthesizing, and interpreting information or data provided in primary sources. For example, a modern-day historian may use The Federalist Papers and other primary sources to reveal historical insights about the series of events that led to the creation of the U.S. Constitution. As a result, the secondary source, based on historical facts, becomes a reliable source of historical data for others to use to create a comprehensive picture of an event and its significance.

The Value of Historical Research for Providing Historical Perspectives

Current global politics has its roots in the past. Historical research offers an essential context for understanding our modern society. It can inform global concepts, such as foreign policy development or international relations. The study of historical events can help leaders make informed decisions that impact society, culture, and the economy.

Take, for example, the Industrial Revolution. Studying the history of the rise of industry in the West helps to put the current world order in perspective. The recorded events of that age reveal that the first designers of the systems of industry, including the United States, dominated the global landscape in the following decades and centuries. Similarly, the digital revolution is creating massive shifts in international politics and society. Historians play a pivotal role in using historical research methods to record and analyze information about these trends to provide future generations with insightful historical perspectives.

In addition to creating meaningful knowledge of global and economic affairs, studying history highlights the perspectives of people and groups who triumphed over adversity. For example, the historical fights for freedom and equality, such as the struggle for women’s voting rights or ending the Jim Crow era in the South, offer relevant context for current events, such as efforts at criminal justice reform.

History also is the story of the collective identity of people and regions. Historical research can help promote a sense of community and highlight the vibrancy of different cultures, creating opportunities for people to become more culturally aware and empowered.

The Tools and Techniques of Historical Research Methods

A primary source is not necessarily an original source. For example, not everyone can access the original essays written by Hamilton because they are precious and must be preserved and protected. However, thanks to digitization, institutions can access, manage, and interpret essential information, artifacts, and images from the essays without fear of degradation.

Using technology to digitize historical information creates what is known as digital history. It offers opportunities to advance scholarly research and expand knowledge to new audiences. For example, individuals can access a digital copy of The Federalist Papers from the Library of Congress’s website anytime, from anywhere. This digital copy can still serve as a primary source because it contains the same content as the original paper version created hundreds of years ago.

As more primary and secondary sources are digitized, researchers are increasingly using artificial intelligence (AI) to search, gather, and analyze these sources. An AI method known as optical character recognition can help historians with digital research. Historians also can use AI techniques to close gaps in historical information. For example, an AI system developed by DeepMind uses deep neural networks to help historians recreate missing pieces and restore ancient Greek texts on stone tablets that are thousands of years old.

As digital tools associated with historical research proliferate, individuals seeking to advance in a history career need to develop technical skills to use advanced technology in their research. Norwich University’s online Master of Arts in History program prepares students with knowledge of historical research methods and critical technology skills to advance in the field of history.

Prepare to Make an Impact

Through effective historical research methods, institutions, organizations, and individuals can learn the significance of past events and communicate important insights for a better future. In museums, government agencies, universities and colleges, nonprofits, and historical associations, the combination of technology and historical research plays a central role in extending the reach of historical information to new audiences. It can also guide leaders charged with making important decisions that can impact geopolitics, society, economic development, community building, and more.

Norwich University’s online Master of Arts in History prepares students with knowledge of historical research methods and skills to use technology to advance their careers across many industries and fields of study. The program’s curriculum offers students the flexibility to choose from four concentrations—Public History, American History, World History, or Legal and Constitutional History—to customize their studies based on their career goals and personal interests.

Evolution of Clinical Research: A History Before and Beyond James Lind

Dr arun bhatt.

President, Clininvent Research Pvt Ltd, Mumbai, India

The evolution of clinical research traverses a long and fascinating journey. From the first recorded trial of legumes in biblical times to the first randomized controlled of trial of streptomycin in 1946, the history of clinical trial covers a wide variety of challenges - scientific, ethical and regulatory. The famous 1747 scurvy trial conducted by James Lind contained most elements of a controlled trial. The UK Medical Research Council's (MRC) trial of patulin for common cold in 1943 was the first double blind controlled trial. This paved the way for the first randomized control trial of streptomycin in pulmonary tuberculosis carried out in 1946 by MRC of the UK. This landmark trial was a model of meticulousness in design and implementation, with systematic enrolment criteria and data collection compared with the ad hoc nature of other contemporary research. Over the years, as the discipline of controlled trials grew in sophistication and influence, the streptomycin trial continues to be referred to as ground breaking. The ethical advances in human protection include several milestones - Nuremberg Code, Declaration of Helsinki, Belmont Report, and 1996, International Conference on Harmonization Good Clinical Practice guidance. In parallel to ethical guidelines, clinical trials started to become embodied in regulation as government authorities began recognizing a need for controlling medical therapies in the early 20th century. As the scientific advances continue to occur, there will be new ethical and regulatory challenges requiring dynamic updates in ethical and legal framework of clinical trials.

“The charm of history and its enigmatic lesson consist in the fact that, from age to age, nothing changes and yet everything is completely different.” - Aldous Huxley

The evolution of clinical research traverses a long and fascinating journey. The recorded history of clinical trials goes back to the biblical descriptions in 500 BC. The journey moves from dietary therapy – legumes and lemons – to drugs. After basic approach of clinical trial was described in 18th century, the efforts were made to refine the design and statistical aspects. These were followed by changes in regulatory and ethics milieu. This article captures the major milestones in the evolution of clinical trials.

562 BC - 1537: Pre-James Lind Era

The world's first clinical trial is recorded in the “Book of Daniel” in The Bible. 1 This experiment resembling a clinical trial was not conducted by a medical, but by King Nebuchadnezzar a resourceful military leader. 1 During his rule in Babylon, Nebuchadnezzar ordered his people to eat only meat and drink only wine, a diet he believed would keep them in sound physical condition. 1 But several young men of royal blood, who preferred to eat vegetables, objected. The king allowed these rebels to follow a diet of legumes and water — but only for 10 days. When Nebuchadnezzar's experiment ended, the vegetarians appeared better nourished than the meat-eaters, so the king permitted the legume lovers to continue their diet. 1 This probably was the one of the first times in evolution of human species that an open uncontrolled human experiment guided a decision about public health.

Avicenna (1025 AD) in his encyclopedic ‘Canon of Medicine’ describes some interesting rules for the testing of drugs. 2 He suggests that in the clinical trial a remedy should be used in its natural state in disease without complications. He recommends that two cases of contrary types be studied and that study be made of the time of action and of the reproducibility of the effects. 2 These rules suggest a contemporary approach for clinical trials. However, there seems to be no record of the application of these principles in practice.

The first clinical trial of a novel therapy was conducted accidentally by the famous surgeon Ambroise Pare in 1537. 1 , 3 In 1537 while serving with the Mareschal de Motegni he was responsible for the treatment of the battlefield wounded soldiers. As the number of wounded was high and the supply of conventional treatment – oil was not adequate to treat all the wounded, he had to resort to unconventional treatment. He describes,' at length my oil lacked and I was constrained to apply in its place a digestive made of yolks of eggs, oil of roses and turpentine. That night I could not sleep at any ease, fearing that by lack of cauterization I would find the wounded upon which I had not used the said oil dead from the poison. I raised myself early to visit them, when beyond my hope I found those to whom I had applied the digestive medicament feeling but little pain, their wounds neither swollen nor inflamed, and having slept through the night. The others to whom I had applied the boiling oil were feverish with much pain and swelling about their wounds. Then I determined never again to burn thus so cruelly the poor wounded by arquebuses’. 2 However, it would take another 200 years before a planned controlled trial would be organized.

1747: James Lind and Scurvy Trial

James Lind is considered the first physician to have conducted a controlled clinical trial of the modern era. 1 – 4 Dr Lind (1716-94), whilst working as a surgeon on a ship, was appalled by the high mortality of scurvy amongst the sailors. He planned a comparative trial of the most promising cure for scurvy. 1 – 4 His vivid description of the trial covers the essential elements of a controlled trial.

Lind describes“”On the 20th of May 1747, I selected twelve patients in the scurvy, on board the Salisbury at sea. Their cases were as similar as I could have them. They all in general had putrid gums, the spots and lassitude, with weakness of the knees. They lay together in one place, being a proper apartment for the sick in the fore-hold; and had one diet common to all, viz. water gruel sweetened with sugar in the morning; fresh mutton-broth often times for dinner; at other times light puddings, boiled biscuit with sugar, etc., and for supper, barley and raisins, rice and currants, sago and wine or the like. Two were ordered each a quart of cyder a day. Two others took twenty-five drops of elixir vitriol three times a day … Two others took two spoonfuls of vinegar three times a day … Two of the worst patients were put on a course of sea-water … Two others had each two oranges and one lemon given them every day … The two remaining patients, took … an electary recommended by a hospital surgeon … The consequence was, that the most sudden and visible good effects were perceived from the use of oranges and lemons; one of those who had taken them, being at the end of six days fit for duty … The other was the best recovered of any in his condition; and … was appointed to attend the rest of the sick. Next to the oranges, I thought the cyder had the best effects …” (Dr James Lind's “Treatise on Scurvy” published in Edinburgh in 1753)

Although the results were clear, Lind hesitated to recommend the use of oranges and lemons because they were too expensive. 3 It was nearly 50 years before the British Navy eventually made lemon juice a compulsory part of the seafarer's diet, and this was soon replaced by lime juice because it was cheaper.

Lind's Treatise of 1953, was written while he was resident in Edinburgh and a Fellow of the Royal College of Physicians, contains not only his well known description of a controlled trial showing that oranges and lemons were dramatically better than the other treatments for the disease, but also a systematic review of previous literature on scurvy. 5

In 2003, Royal College of Physicians established The James Lind Library to commemorate 250 th anniversary of publication of Dr Lind's pioneering contribution “Treatise on Scurvy”. The James Lind Library ( www.jameslindlibrary.org ) was created to improve public and professional general knowledge about fair tests of treatments in healthcare and their history. 5 This library is a website ( www.jameslindlibrary.org ) that introduces visitors to the principles of fair tests of treatments, with a series of short, illustrated essays. In 2003, Scientific American awarded the Library a Sci/Tech web award. The publicity and popularity of the James Lind Library has made 20 May to be designated International Clinical Trials Day, because James Lind's celebrated controlled trial began on that day in 1747. 5

1800: Arrival of Placebo

It took another century before the emergence of another important mile stone in the history of modern clinical trial: the placebo. The word placebo first appeared in medical literature in the early 1800s. 1 Hooper's Medical Dictionary of 1811 defined it as “an epithet given to any medicine more to please than benefit the patient.” However, it was only in 1863 that United States physician Austin Flint planned the first clinical study comparing a dummy remedy to an active treatment. He treated 13 patients suffering from rheumatism with an herbal extract which was advised instead of an established remedy. In 1886, Flint described the study in his book A Treatise on the Principles and Practice of Medicine. “This was given regularly, and became well known in my wards as the ‘placeboic remedy’ for rheumatism. The favorable progress of the cases was such as to secure for the remedy generally the entire confidence of the patients.”

1943: The First Double blind Controlled Trial - Patulin for Common Cold

The Medical Research Council (MRC) UK carried out a trial in 1943-4 to investigate patulin treatment for (an extract of Penicillium patulinum) the common cold. 6 This was the first double blind comparative trial with concurrent controls in the general population in recent times. 6 It was one of the last trial with non-randomized or quasi-randomized allocation of subjects. 6 The MRC Patulin Clinical Trials Committee (1943) was chaired by Sir Harold Himsworth, and its statisticians were M Greenwood and W J Martin. This nationwide study enrolled over a thousand British office and factory workers suffering from colds. This was quite a challenging endeavor in wartime,

The study was rigorously controlled by keeping the physician and the patient blinded to the treatment. The treatment allocation was done using an alternation procedure. A nurse allocated the treatment in strict rotation in a separate room. The nurse filed the record counterfoil separately, and detached the code label for the appropriate bottle before asking the patient to visit the doctor. 6 The statisticians considered this an effective random concurrent allocation. .However, the outcome of the trial was disappointing as the analysis of trial data did not show any protective effect of patulin. 6

1946 First Randomized Curative Trial - The Randomized Controlled Trial of Streptomycin

The idea of randomization was introduced in 1923. However, the first randomized control trial of streptomycin in pulmonary tuberculosis was carried out in 1946 by MRC of the UK. 6 , 7 The MRC Streptomycin in Tuberculosis Trials Committee (1946) was chaired by Sir Geoffrey Marshall, and the statistician was Sir Austin Bradford Hill and Philip Hart, who later directed the MRC's tuberculosis research unit, served as secretary. Marc Daniels, as the “registrar” coordinated the clinicians at the participating hospitals. The trial began in 1947. As the amount of streptomycin available from US was limited, it was ethically acceptable for the control subjects to be untreated by the drug—a statistician's dream. 6 This trial was a model of meticulousness in design and implementation, with systematic enrolment criteria and data collection compared with the ad hoc nature of other contemporary research 8 A key advantage of Dr Hill's randomization scheme over alternation procedure was “allocation concealment” at the time patients were enrolled in the trial. Another significant feature of the trial was the use of objective measures such as interpretation of x-rays by experts who were blinded to the patient's treatment assignment. 8

Sir Bradford Hill had formed his allocation ideas over several years (with randomisation replacing alternation in order to better conceal the allocation schedule), but had only tried them out in disease prevention. Dr Hill instituted randomization – a new statistical process which has been described in detail in the landmark BMJ paper of 1948. 7

“Determination of whether a patient would be treated by streptomycin and bed-rest (S case) or by bed-rest alone (C case) was made by reference to a statistical series based on random sampling numbers drawn up for each sex at each centre by Professor Bradford Hill; the details of the series were unknown to any of the investigators or to the co--coordinator and were contained in a set of sealed envelopes, each bearing on the outside only the name of the hospital and a number. After acceptance of a patient by the panel, and before admission to the streptomycin centre, the appropriate numbered envelope was opened at the central office; the card inside told if the patient was to be an S or a C case, and this information was then given to the medical officer of the centre. Patients were not told before admission that they were to get special treatment. C patients did not know throughout their stay in hospital that they were control patients in a special study; they were in fact treated as they would have been in the past, the sole difference being that they had been admitted to the centre more rapidly than was normal. Usually they were not in the same wards as S patients, but the same regime was maintained

Sir Bradford Hill had been anxious that physicians would be unwilling to give up the doctrine of anecdotal experience. However, the trial quickly became a model of design and implementation and gave a boost to Dr Hill's views and subsequent teaching, and resulted, after some years, in the present virtually universal use of randomised allocation in clinical trials. 6 The greatest influence of this trial lay in its methods which have affected virtually every area of clinical medicine. 8 Over the years, as the discipline of controlled trials grew in sophistication and influence, the streptomycin trial continues to be referred to as ground breaking. 8

Evolution of Ethical and Regulatory Framework

The ethical framework for human subject protection has its origins in the ancient Hippocratic Oath, which specified a prime duty of a physician – to avoid harming the patient. However, this oath was not much respected in human experimentation and most advances in protection for human subjects have been a response to human abuses e.g. World War II experiments.

The first International Guidance on the ethics of medical research involving subjects – the Nuremberg Code was formulated in 1947. Although informed consent for participation in research was described in 1900, the Nuremberg Code highlighted the essentiality of voluntariness of this consent. 9 In 1948, Universal Declaration of Human Rights (adopted by the General Assembly of the United Nations) expressed concern about rights of human beings being subjected to involuntary maltreatment. 9 The brush with thalidomide tragedy helped the U.S. pass the 1962 Kefauver-Harris amendments, which strengthened federal oversight of drug testing and included a requirement for informed consent. 10

In 1964 at Helsinki, the World Medical Association articulated general principles and specific guidelines on use of human subjects in medical research, known as the Helsinki Declaration. The Helsinki Declaration has been undergoing changes every few years the last one being in 2008. However, the use of placebo and post-trial access continue to be debatable issues.

In 1966, the International Covenant on Civil and Political Rights specifically stated, ‘No one shall be subjected to torture or to cruel, inhuman or degrading treatment or punishment. In particular, no one shall be subjected without his consent to medical or scientific treatment.’ 9 Dr. Henry Beecher's 1966 study of abuses and the discovery of human exploitation of Tuskegee study in the 1970s reinforced the call for tighter regulation of government funded human research. 10 The US National Research Act of 1974 and Belmont Report of 1979 were major efforts in shaping ethics of human experimentation. In 1996, International Conference on Harmonization published Good Clinical Practice, which has become the universal standard for ethical conduct of clinical trials.

In parallel to ethical guidelines, clinical trials started to become embodied in regulation as government authorities began recognizing a need for controlling medical therapies in the early 20th century. The FDA was founded in 1862 as a scientific institution and became a law enforcement organization after the US Congress passed the Food and Drugs Act in 1906. After that, legislation progressively demanded greater accountability for marketing food and drugs and the need for testing drugs in clinical trials increased. The regulatory and ethical milieu will continue to evolve as new scientific disciplines and technologies become part of drug development.

Evolution of Clinical Trials in India

India has recently been recognized as an attractive country for clinical trials. But the country's journey in clinical research field has a long history. India has a rich heritage of traditional medicine – Ayurveda. The classic ayurvedic texts contain detailed observations on diseases and in-depth guidance on remedies. It is likely that these descriptions are based on direct observations made by the ancient ayurveda experts. However, there is no recorded documentation in the ancient texts of any clinical experiments. Hence, one has to fall back on current history of medical research in India.

The major historic milestones of the Indian Council of Medical Research reflect, in many ways, the growth and development of medical research in the country over the last nine decades. First meeting of the Governing Body of the Indian Research Fund Association (IRFA) was held on November 15, 1911 at the Plague Laboratory, Bombay, under the Chairmanship of Sir Harcourt Butler. 11 At the 2nd meeting of the Governing Body in 1912, a historic decision was taken to start a journal for Indian Medical research. Between 1918--20, several projects on beriberi, malaria, kala azar and indigenous drugs were initiated. In 1945, a Clinical Research Unit – the first research unit of IRFA attached to a medical institution- was established at the Indian Cancer Research Centre, Bombay. In 1949, IRFA was redesignated as the Indian Council of Medical Research. Over next 60 years, ICMR established many national research centers in the fields of nutrition, tuberculosis, leprosy, viral disease, cholera, enteric disease, reproductive disorders, toxicology, cancer, traditional medicine, gas disaster, genetics, AIDS etc.

The Central Ethical Committee of ICMR on Human Research constituted under the Chairmanship of Hon'ble Justice (Retired) M.N. Venkatachaliah held its first meeting on September 10, 1996. Several subcommittees were constituted to consider ethical issues in specific areas e.g., Epidemiological Research; Clinical Evaluation of Products to be used on Humans; Organ Transplantation; Human Genetics, etc. The committee released Ethical Guidelines for Biomedical Research on Human Participants in 2000 which were revised in 2006. 9

Schedule Y of Drugs and Cosmetics Act came into force in 1988 and established the regulatory guidelines for clinical trial (CT) permission. The schedule did force the industry to conduct Phase III clinical trials for registration of a new drug and supported growth of a predominantly generic Indian pharmaceutical industry. However, this schedule only permitted clinical trials at a phase lower than its global status. This phase lag obstructed integration of India in global clinical development.

The next major step has been revision of Schedule Y in Jan 2005. 12 As compared to Schedule Y 1988, which had narrow and restrictive definitions of clinical trial phases, the amended Schedule Y 2005 provided pragmatic definitions for Phase I to IV. 12 The definitions and guidelines for clinical trial phases are broad and rational. The earlier restrictions on number patients and centers in early phases stipulated in Schedule Y 1988 were removed allowing the sponsor company freedom to decide these in relation to protocol requirements. The phase lag requirements gave way to acceptance of concurrent Phase II-III as part of global clinical trials.

Schedule Y 2005 legalized Indian GCP guidelines of 2001. This schedule stipulated GCP responsibilities of ethics committee (EC), investigator and sponsor and suggested formats for critical documents e.g. consent, report, EC approval, reporting of serious adverse event. These amendments in Schedule Y have been a major step forward in direction of GCP compliant trials and have provided the much-needed regulatory support to GCP guidelines.

Since the Scurvy trial, clinical trials have evolved into a standardized procedure, focusing on scientific assessment of efficacy and guarding the patient safety. As the discipline of drug development is enriched by novel therapies and technologies, there will always be a continuing need to balance medical progress and patient safety. As the scientific advances continue to occur, there will be new ethical and regulatory challenges requiring dynamic updates in ethical and legal framework of clinical trials.

• The 25 Most Influential Psychological Experiments in History

While each year thousands and thousands of studies are completed in the many specialty areas of psychology, there are a handful that, over the years, have had a lasting impact in the psychological community as a whole. Some of these were dutifully conducted, keeping within the confines of ethical and practical guidelines. Others pushed the boundaries of human behavior during their psychological experiments and created controversies that still linger to this day. And still others were not designed to be true psychological experiments, but ended up as beacons to the psychological community in proving or disproving theories.

This is a list of the 25 most influential psychological experiments still being taught to psychology students of today.

1. A Class Divided

Study conducted by: jane elliott.

Study Conducted in 1968 in an Iowa classroom

Experiment Details: Jane Elliott’s famous experiment was inspired by the assassination of Dr. Martin Luther King Jr. and the inspirational life that he led. The third grade teacher developed an exercise, or better yet, a psychological experiment, to help her Caucasian students understand the effects of racism and prejudice.

Elliott divided her class into two separate groups: blue-eyed students and brown-eyed students. On the first day, she labeled the blue-eyed group as the superior group and from that point forward they had extra privileges, leaving the brown-eyed children to represent the minority group. She discouraged the groups from interacting and singled out individual students to stress the negative characteristics of the children in the minority group. What this exercise showed was that the children’s behavior changed almost instantaneously. The group of blue-eyed students performed better academically and even began bullying their brown-eyed classmates. The brown-eyed group experienced lower self-confidence and worse academic performance. The next day, she reversed the roles of the two groups and the blue-eyed students became the minority group.

At the end of the experiment, the children were so relieved that they were reported to have embraced one another and agreed that people should not be judged based on outward appearances. This exercise has since been repeated many times with similar outcomes.

2. Asch Conformity Study

Study conducted by: dr. solomon asch.

Study Conducted in 1951 at Swarthmore College

Experiment Details: Dr. Solomon Asch conducted a groundbreaking study that was designed to evaluate a person’s likelihood to conform to a standard when there is pressure to do so.

A group of participants were shown pictures with lines of various lengths and were then asked a simple question: Which line is longest? The tricky part of this study was that in each group only one person was a true participant. The others were actors with a script. Most of the actors were instructed to give the wrong answer. Strangely, the one true participant almost always agreed with the majority, even though they knew they were giving the wrong answer.

The results of this study are important when we study social interactions among individuals in groups. This study is a famous example of the temptation many of us experience to conform to a standard during group situations and it showed that people often care more about being the same as others than they do about being right. It is still recognized as one of the most influential psychological experiments for understanding human behavior.

3. Bobo Doll Experiment

Study conducted by: dr. alburt bandura.

Study Conducted between 1961-1963 at Stanford University

In his groundbreaking study he separated participants into three groups:

• one was exposed to a video of an adult showing aggressive behavior towards a Bobo doll
• another was exposed to video of a passive adult playing with the Bobo doll
• the third formed a control group

Children watched their assigned video and then were sent to a room with the same doll they had seen in the video (with the exception of those in the control group). What the researcher found was that children exposed to the aggressive model were more likely to exhibit aggressive behavior towards the doll themselves. The other groups showed little imitative aggressive behavior. For those children exposed to the aggressive model, the number of derivative physical aggressions shown by the boys was 38.2 and 12.7 for the girls.

The study also showed that boys exhibited more aggression when exposed to aggressive male models than boys exposed to aggressive female models. When exposed to aggressive male models, the number of aggressive instances exhibited by boys averaged 104. This is compared to 48.4 aggressive instances exhibited by boys who were exposed to aggressive female models.

While the results for the girls show similar findings, the results were less drastic. When exposed to aggressive female models, the number of aggressive instances exhibited by girls averaged 57.7. This is compared to 36.3 aggressive instances exhibited by girls who were exposed to aggressive male models. The results concerning gender differences strongly supported Bandura’s secondary prediction that children will be more strongly influenced by same-sex models. The Bobo Doll Experiment showed a groundbreaking way to study human behavior and it’s influences.

4. Car Crash Experiment

Study conducted by: elizabeth loftus and john palmer.

Study Conducted in 1974 at The University of California in Irvine

The participants watched slides of a car accident and were asked to describe what had happened as if they were eyewitnesses to the scene. The participants were put into two groups and each group was questioned using different wording such as “how fast was the car driving at the time of impact?” versus “how fast was the car going when it smashed into the other car?” The experimenters found that the use of different verbs affected the participants’ memories of the accident, showing that memory can be easily distorted.

This research suggests that memory can be easily manipulated by questioning technique. This means that information gathered after the event can merge with original memory causing incorrect recall or reconstructive memory. The addition of false details to a memory of an event is now referred to as confabulation. This concept has very important implications for the questions used in police interviews of eyewitnesses.

5. Cognitive Dissonance Experiment

Study conducted by: leon festinger and james carlsmith.

Study Conducted in 1957 at Stanford University

Experiment Details: The concept of cognitive dissonance refers to a situation involving conflicting:

This conflict produces an inherent feeling of discomfort leading to a change in one of the attitudes, beliefs or behaviors to minimize or eliminate the discomfort and restore balance.

Cognitive dissonance was first investigated by Leon Festinger, after an observational study of a cult that believed that the earth was going to be destroyed by a flood. Out of this study was born an intriguing experiment conducted by Festinger and Carlsmith where participants were asked to perform a series of dull tasks (such as turning pegs in a peg board for an hour). Participant’s initial attitudes toward this task were highly negative.

They were then paid either $1 or $20 to tell a participant waiting in the lobby that the tasks were really interesting. Almost all of the participants agreed to walk into the waiting room and persuade the next participant that the boring experiment would be fun. When the participants were later asked to evaluate the experiment, the participants who were paid only $1 rated the tedious task as more fun and enjoyable than the participants who were paid $20 to lie.

Being paid only $1 is not sufficient incentive for lying and so those who were paid $1 experienced dissonance. They could only overcome that cognitive dissonance by coming to believe that the tasks really were interesting and enjoyable. Being paid $20 provides a reason for turning pegs and there is therefore no dissonance.

6. Fantz’s Looking Chamber

Study conducted by: robert l. fantz.

Study Conducted in 1961 at the University of Illinois

Experiment Details: The study conducted by Robert L. Fantz is among the simplest, yet most important in the field of infant development and vision. In 1961, when this experiment was conducted, there very few ways to study what was going on in the mind of an infant. Fantz realized that the best way was to simply watch the actions and reactions of infants. He understood the fundamental factor that if there is something of interest near humans, they generally look at it.

To test this concept, Fantz set up a display board with two pictures attached. On one was a bulls-eye. On the other was the sketch of a human face. This board was hung in a chamber where a baby could lie safely underneath and see both images. Then, from behind the board, invisible to the baby, he peeked through a hole to watch what the baby looked at. This study showed that a two-month old baby looked twice as much at the human face as it did at the bulls-eye. This suggests that human babies have some powers of pattern and form selection. Before this experiment it was thought that babies looked out onto a chaotic world of which they could make little sense.

7. Hawthorne Effect

Study conducted by: henry a. landsberger.

Study Conducted in 1955 at Hawthorne Works in Chicago, Illinois

Landsberger performed the study by analyzing data from experiments conducted between 1924 and 1932, by Elton Mayo, at the Hawthorne Works near Chicago. The company had commissioned studies to evaluate whether the level of light in a building changed the productivity of the workers. What Mayo found was that the level of light made no difference in productivity. The workers increased their output whenever the amount of light was switched from a low level to a high level, or vice versa.

The researchers noticed a tendency that the workers’ level of efficiency increased when any variable was manipulated. The study showed that the output changed simply because the workers were aware that they were under observation. The conclusion was that the workers felt important because they were pleased to be singled out. They increased productivity as a result. Being singled out was the factor dictating increased productivity, not the changing lighting levels, or any of the other factors that they experimented upon.

The Hawthorne Effect has become one of the hardest inbuilt biases to eliminate or factor into the design of any experiment in psychology and beyond.

8. Kitty Genovese Case

Study conducted by: new york police force.

Study Conducted in 1964 in New York City

Experiment Details: The murder case of Kitty Genovese was never intended to be a psychological experiment, however it ended up having serious implications for the field.

According to a New York Times article, almost 40 neighbors witnessed Kitty Genovese being savagely attacked and murdered in Queens, New York in 1964. Not one neighbor called the police for help. Some reports state that the attacker briefly left the scene and later returned to “finish off” his victim. It was later uncovered that many of these facts were exaggerated. (There were more likely only a dozen witnesses and records show that some calls to police were made).

What this case later become famous for is the “Bystander Effect,” which states that the more bystanders that are present in a social situation, the less likely it is that anyone will step in and help. This effect has led to changes in medicine, psychology and many other areas. One famous example is the way CPR is taught to new learners. All students in CPR courses learn that they must assign one bystander the job of alerting authorities which minimizes the chances of no one calling for assistance.

9. Learned Helplessness Experiment

Study conducted by: martin seligman.

Study Conducted in 1967 at the University of Pennsylvania

Seligman’s experiment involved the ringing of a bell and then the administration of a light shock to a dog. After a number of pairings, the dog reacted to the shock even before it happened. As soon as the dog heard the bell, he reacted as though he’d already been shocked.

During the course of this study something unexpected happened. Each dog was placed in a large crate that was divided down the middle with a low fence. The dog could see and jump over the fence easily. The floor on one side of the fence was electrified, but not on the other side of the fence. Seligman placed each dog on the electrified side and administered a light shock. He expected the dog to jump to the non-shocking side of the fence. In an unexpected turn, the dogs simply laid down.

The hypothesis was that as the dogs learned from the first part of the experiment that there was nothing they could do to avoid the shocks, they gave up in the second part of the experiment. To prove this hypothesis the experimenters brought in a new set of animals and found that dogs with no history in the experiment would jump over the fence.

This condition was described as learned helplessness. A human or animal does not attempt to get out of a negative situation because the past has taught them that they are helpless.

10. Little Albert Experiment

Study conducted by: john b. watson and rosalie rayner.

Study Conducted in 1920 at Johns Hopkins University

The experiment began by placing a white rat in front of the infant, who initially had no fear of the animal. Watson then produced a loud sound by striking a steel bar with a hammer every time little Albert was presented with the rat. After several pairings (the noise and the presentation of the white rat), the boy began to cry and exhibit signs of fear every time the rat appeared in the room. Watson also created similar conditioned reflexes with other common animals and objects (rabbits, Santa beard, etc.) until Albert feared them all.

This study proved that classical conditioning works on humans. One of its most important implications is that adult fears are often connected to early childhood experiences.

11. Magical Number Seven

Study conducted by: george a. miller.

Study Conducted in 1956 at Princeton University

Experiment Details:   Frequently referred to as “ Miller’s Law,” the Magical Number Seven experiment purports that the number of objects an average human can hold in working memory is 7 ± 2. This means that the human memory capacity typically includes strings of words or concepts ranging from 5-9. This information on the limits to the capacity for processing information became one of the most highly cited papers in psychology.

The Magical Number Seven Experiment was published in 1956 by cognitive psychologist George A. Miller of Princeton University’s Department of Psychology in Psychological Review .  In the article, Miller discussed a concurrence between the limits of one-dimensional absolute judgment and the limits of short-term memory.

In a one-dimensional absolute-judgment task, a person is presented with a number of stimuli that vary on one dimension (such as 10 different tones varying only in pitch). The person responds to each stimulus with a corresponding response (learned before).

Performance is almost perfect up to five or six different stimuli but declines as the number of different stimuli is increased. This means that a human’s maximum performance on one-dimensional absolute judgment can be described as an information store with the maximum capacity of approximately 2 to 3 bits of information There is the ability to distinguish between four and eight alternatives.

12. Pavlov’s Dog Experiment

Study conducted by: ivan pavlov.

Study Conducted in the 1890s at the Military Medical Academy in St. Petersburg, Russia

Pavlov began with the simple idea that there are some things that a dog does not need to learn. He observed that dogs do not learn to salivate when they see food. This reflex is “hard wired” into the dog. This is an unconditioned response (a stimulus-response connection that required no learning).

Pavlov outlined that there are unconditioned responses in the animal by presenting a dog with a bowl of food and then measuring its salivary secretions. In the experiment, Pavlov used a bell as his neutral stimulus. Whenever he gave food to his dogs, he also rang a bell. After a number of repeats of this procedure, he tried the bell on its own. What he found was that the bell on its own now caused an increase in salivation. The dog had learned to associate the bell and the food. This learning created a new behavior. The dog salivated when he heard the bell. Because this response was learned (or conditioned), it is called a conditioned response. The neutral stimulus has become a conditioned stimulus.

This theory came to be known as classical conditioning.

13. Robbers Cave Experiment

Study conducted by: muzafer and carolyn sherif.

Study Conducted in 1954 at the University of Oklahoma

Experiment Details: This experiment, which studied group conflict, is considered by most to be outside the lines of what is considered ethically sound.

In 1954 researchers at the University of Oklahoma assigned 22 eleven- and twelve-year-old boys from similar backgrounds into two groups. The two groups were taken to separate areas of a summer camp facility where they were able to bond as social units. The groups were housed in separate cabins and neither group knew of the other’s existence for an entire week. The boys bonded with their cabin mates during that time. Once the two groups were allowed to have contact, they showed definite signs of prejudice and hostility toward each other even though they had only been given a very short time to develop their social group. To increase the conflict between the groups, the experimenters had them compete against each other in a series of activities. This created even more hostility and eventually the groups refused to eat in the same room. The final phase of the experiment involved turning the rival groups into friends. The fun activities the experimenters had planned like shooting firecrackers and watching movies did not initially work, so they created teamwork exercises where the two groups were forced to collaborate. At the end of the experiment, the boys decided to ride the same bus home, demonstrating that conflict can be resolved and prejudice overcome through cooperation.

Many critics have compared this study to Golding’s Lord of the Flies novel as a classic example of prejudice and conflict resolution.

14. Ross’ False Consensus Effect Study

Study conducted by: lee ross.

Study Conducted in 1977 at Stanford University

Experiment Details: In 1977, a social psychology professor at Stanford University named Lee Ross conducted an experiment that, in lay terms, focuses on how people can incorrectly conclude that others think the same way they do, or form a “false consensus” about the beliefs and preferences of others. Ross conducted the study in order to outline how the “false consensus effect” functions in humans.

Featured Programs

In the first part of the study, participants were asked to read about situations in which a conflict occurred and then were told two alternative ways of responding to the situation. They were asked to do three things:

• Guess which option other people would choose
• Say which option they themselves would choose
• Describe the attributes of the person who would likely choose each of the two options

What the study showed was that most of the subjects believed that other people would do the same as them, regardless of which of the two responses they actually chose themselves. This phenomenon is referred to as the false consensus effect, where an individual thinks that other people think the same way they do when they may not. The second observation coming from this important study is that when participants were asked to describe the attributes of the people who will likely make the choice opposite of their own, they made bold and sometimes negative predictions about the personalities of those who did not share their choice.

15. The Schacter and Singer Experiment on Emotion

Study conducted by: stanley schachter and jerome e. singer.

Study Conducted in 1962 at Columbia University

Experiment Details: In 1962 Schachter and Singer conducted a ground breaking experiment to prove their theory of emotion.

In the study, a group of 184 male participants were injected with epinephrine, a hormone that induces arousal including increased heartbeat, trembling, and rapid breathing. The research participants were told that they were being injected with a new medication to test their eyesight. The first group of participants was informed the possible side effects that the injection might cause while the second group of participants were not. The participants were then placed in a room with someone they thought was another participant, but was actually a confederate in the experiment. The confederate acted in one of two ways: euphoric or angry. Participants who had not been informed about the effects of the injection were more likely to feel either happier or angrier than those who had been informed.

What Schachter and Singer were trying to understand was the ways in which cognition or thoughts influence human emotion. Their study illustrates the importance of how people interpret their physiological states, which form an important component of your emotions. Though their cognitive theory of emotional arousal dominated the field for two decades, it has been criticized for two main reasons: the size of the effect seen in the experiment was not that significant and other researchers had difficulties repeating the experiment.

16. Selective Attention / Invisible Gorilla Experiment

Study conducted by: daniel simons and christopher chabris.

Study Conducted in 1999 at Harvard University

Experiment Details: In 1999 Simons and Chabris conducted their famous awareness test at Harvard University.

Participants in the study were asked to watch a video and count how many passes occurred between basketball players on the white team. The video moves at a moderate pace and keeping track of the passes is a relatively easy task. What most people fail to notice amidst their counting is that in the middle of the test, a man in a gorilla suit walked onto the court and stood in the center before walking off-screen.

The study found that the majority of the subjects did not notice the gorilla at all, proving that humans often overestimate their ability to effectively multi-task. What the study set out to prove is that when people are asked to attend to one task, they focus so strongly on that element that they may miss other important details.

17. Stanford Prison Study

Study conducted by philip zimbardo.

Study Conducted in 1971 at Stanford University

The Stanford Prison Experiment was designed to study behavior of “normal” individuals when assigned a role of prisoner or guard. College students were recruited to participate. They were assigned roles of “guard” or “inmate.”  Zimbardo played the role of the warden. The basement of the psychology building was the set of the prison. Great care was taken to make it look and feel as realistic as possible.

The prison guards were told to run a prison for two weeks. They were told not to physically harm any of the inmates during the study. After a few days, the prison guards became very abusive verbally towards the inmates. Many of the prisoners became submissive to those in authority roles. The Stanford Prison Experiment inevitably had to be cancelled because some of the participants displayed troubling signs of breaking down mentally.

Although the experiment was conducted very unethically, many psychologists believe that the findings showed how much human behavior is situational. People will conform to certain roles if the conditions are right. The Stanford Prison Experiment remains one of the most famous psychology experiments of all time.

18. Stanley Milgram Experiment

Study conducted by stanley milgram.

Study Conducted in 1961 at Stanford University

Experiment Details: This 1961 study was conducted by Yale University psychologist Stanley Milgram. It was designed to measure people’s willingness to obey authority figures when instructed to perform acts that conflicted with their morals. The study was based on the premise that humans will inherently take direction from authority figures from very early in life.

Participants were told they were participating in a study on memory. They were asked to watch another person (an actor) do a memory test. They were instructed to press a button that gave an electric shock each time the person got a wrong answer. (The actor did not actually receive the shocks, but pretended they did).

Participants were told to play the role of “teacher” and administer electric shocks to “the learner,” every time they answered a question incorrectly. The experimenters asked the participants to keep increasing the shocks. Most of them obeyed even though the individual completing the memory test appeared to be in great pain. Despite these protests, many participants continued the experiment when the authority figure urged them to. They increased the voltage after each wrong answer until some eventually administered what would be lethal electric shocks.

This experiment showed that humans are conditioned to obey authority and will usually do so even if it goes against their natural morals or common sense.

19. Surrogate Mother Experiment

Study conducted by: harry harlow.

Study Conducted from 1957-1963 at the University of Wisconsin

Experiment Details: In a series of controversial experiments during the late 1950s and early 1960s, Harry Harlow studied the importance of a mother’s love for healthy childhood development.

In order to do this he separated infant rhesus monkeys from their mothers a few hours after birth and left them to be raised by two “surrogate mothers.” One of the surrogates was made of wire with an attached bottle for food. The other was made of soft terrycloth but lacked food. The researcher found that the baby monkeys spent much more time with the cloth mother than the wire mother, thereby proving that affection plays a greater role than sustenance when it comes to childhood development. They also found that the monkeys that spent more time cuddling the soft mother grew up to healthier.

This experiment showed that love, as demonstrated by physical body contact, is a more important aspect of the parent-child bond than the provision of basic needs. These findings also had implications in the attachment between fathers and their infants when the mother is the source of nourishment.

20. The Good Samaritan Experiment

Study conducted by: john darley and daniel batson.

Study Conducted in 1973 at The Princeton Theological Seminary (Researchers were from Princeton University)

Experiment Details: In 1973, an experiment was created by John Darley and Daniel Batson, to investigate the potential causes that underlie altruistic behavior. The researchers set out three hypotheses they wanted to test:

• People thinking about religion and higher principles would be no more inclined to show helping behavior than laymen.
• People in a rush would be much less likely to show helping behavior.
• People who are religious for personal gain would be less likely to help than people who are religious because they want to gain some spiritual and personal insights into the meaning of life.

Student participants were given some religious teaching and instruction. They were then were told to travel from one building to the next. Between the two buildings was a man lying injured and appearing to be in dire need of assistance. The first variable being tested was the degree of urgency impressed upon the subjects, with some being told not to rush and others being informed that speed was of the essence.

The results of the experiment were intriguing, with the haste of the subject proving to be the overriding factor. When the subject was in no hurry, nearly two-thirds of people stopped to lend assistance. When the subject was in a rush, this dropped to one in ten.

People who were on the way to deliver a speech about helping others were nearly twice as likely to help as those delivering other sermons,. This showed that the thoughts of the individual were a factor in determining helping behavior. Religious beliefs did not appear to make much difference on the results. Being religious for personal gain, or as part of a spiritual quest, did not appear to make much of an impact on the amount of helping behavior shown.

21. The Halo Effect Experiment

Study conducted by: richard e. nisbett and timothy decamp wilson.

Study Conducted in 1977 at the University of Michigan

Experiment Details: The Halo Effect states that people generally assume that people who are physically attractive are more likely to:

• be intelligent
• be friendly
• display good judgment

To prove their theory, Nisbett and DeCamp Wilson created a study to prove that people have little awareness of the nature of the Halo Effect. They’re not aware that it influences:

• their personal judgments
• the production of a more complex social behavior

In the experiment, college students were the research participants. They were asked to evaluate a psychology instructor as they view him in a videotaped interview. The students were randomly assigned to one of two groups. Each group was shown one of two different interviews with the same instructor. The instructor is a native French-speaking Belgian who spoke English with a noticeable accent. In the first video, the instructor presented himself as someone:

• respectful of his students’ intelligence and motives
• flexible in his approach to teaching
• enthusiastic about his subject matter

In the second interview, he presented himself as much more unlikable. He was cold and distrustful toward the students and was quite rigid in his teaching style.

After watching the videos, the subjects were asked to rate the lecturer on:

• physical appearance

His mannerisms and accent were kept the same in both versions of videos. The subjects were asked to rate the professor on an 8-point scale ranging from “like extremely” to “dislike extremely.” Subjects were also told that the researchers were interested in knowing “how much their liking for the teacher influenced the ratings they just made.” Other subjects were asked to identify how much the characteristics they just rated influenced their liking of the teacher.

After responding to the questionnaire, the respondents were puzzled about their reactions to the videotapes and to the questionnaire items. The students had no idea why they gave one lecturer higher ratings. Most said that how much they liked the lecturer had not affected their evaluation of his individual characteristics at all.

The interesting thing about this study is that people can understand the phenomenon, but they are unaware when it is occurring. Without realizing it, humans make judgments. Even when it is pointed out, they may still deny that it is a product of the halo effect phenomenon.

22. The Marshmallow Test

Study conducted by: walter mischel.

Study Conducted in 1972 at Stanford University

In his 1972 Marshmallow Experiment, children ages four to six were taken into a room where a marshmallow was placed in front of them on a table. Before leaving each of the children alone in the room, the experimenter informed them that they would receive a second marshmallow if the first one was still on the table after they returned in 15 minutes. The examiner recorded how long each child resisted eating the marshmallow and noted whether it correlated with the child’s success in adulthood. A small number of the 600 children ate the marshmallow immediately and one-third delayed gratification long enough to receive the second marshmallow.

In follow-up studies, Mischel found that those who deferred gratification were significantly more competent and received higher SAT scores than their peers. This characteristic likely remains with a person for life. While this study seems simplistic, the findings outline some of the foundational differences in individual traits that can predict success.

23. The Monster Study

Study conducted by: wendell johnson.

Study Conducted in 1939 at the University of Iowa

Experiment Details: The Monster Study received this negative title due to the unethical methods that were used to determine the effects of positive and negative speech therapy on children.

Wendell Johnson of the University of Iowa selected 22 orphaned children, some with stutters and some without. The children were in two groups. The group of children with stutters was placed in positive speech therapy, where they were praised for their fluency. The non-stutterers were placed in negative speech therapy, where they were disparaged for every mistake in grammar that they made.

As a result of the experiment, some of the children who received negative speech therapy suffered psychological effects and retained speech problems for the rest of their lives. They were examples of the significance of positive reinforcement in education.

The initial goal of the study was to investigate positive and negative speech therapy. However, the implication spanned much further into methods of teaching for young children.

24. Violinist at the Metro Experiment

Study conducted by: staff at the washington post.

Study Conducted in 2007 at a Washington D.C. Metro Train Station

During the study, pedestrians rushed by without realizing that the musician playing at the entrance to the metro stop was Grammy-winning musician, Joshua Bell. Two days before playing in the subway, he sold out at a theater in Boston where the seats average $100. He played one of the most intricate pieces ever written with a violin worth 3.5 million dollars. In the 45 minutes the musician played his violin, only 6 people stopped and stayed for a while. Around 20 gave him money, but continued to walk their normal pace. He collected $32.

The study and the subsequent article organized by the Washington Post was part of a social experiment looking at:

• the priorities of people

Gene Weingarten wrote about the social experiment: “In a banal setting at an inconvenient time, would beauty transcend?” Later he won a Pulitzer Prize for his story. Some of the questions the article addresses are:

• Do we perceive beauty?
• Do we stop to appreciate it?
• Do we recognize the talent in an unexpected context?

As it turns out, many of us are not nearly as perceptive to our environment as we might like to think.

25. Visual Cliff Experiment

Study conducted by: eleanor gibson and richard walk.

Study Conducted in 1959 at Cornell University

Experiment Details: In 1959, psychologists Eleanor Gibson and Richard Walk set out to study depth perception in infants. They wanted to know if depth perception is a learned behavior or if it is something that we are born with. To study this, Gibson and Walk conducted the visual cliff experiment.

They studied 36 infants between the ages of six and 14 months, all of whom could crawl. The infants were placed one at a time on a visual cliff. A visual cliff was created using a large glass table that was raised about a foot off the floor. Half of the glass table had a checker pattern underneath in order to create the appearance of a ‘shallow side.’

In order to create a ‘deep side,’ a checker pattern was created on the floor; this side is the visual cliff. The placement of the checker pattern on the floor creates the illusion of a sudden drop-off. Researchers placed a foot-wide centerboard between the shallow side and the deep side. Gibson and Walk found the following:

• Nine of the infants did not move off the centerboard.
• All of the 27 infants who did move crossed into the shallow side when their mothers called them from the shallow side.
• Three of the infants crawled off the visual cliff toward their mother when called from the deep side.
• When called from the deep side, the remaining 24 children either crawled to the shallow side or cried because they could not cross the visual cliff and make it to their mother.

What this study helped demonstrate is that depth perception is likely an inborn train in humans.

Among these experiments and psychological tests, we see boundaries pushed and theories taking on a life of their own. It is through the endless stream of psychological experimentation that we can see simple hypotheses become guiding theories for those in this field. The greater field of psychology became a formal field of experimental study in 1879, when Wilhelm Wundt established the first laboratory dedicated solely to psychological research in Leipzig, Germany. Wundt was the first person to refer to himself as a psychologist. Since 1879, psychology has grown into a massive collection of:

• methods of practice

It’s also a specialty area in the field of healthcare. None of this would have been possible without these and many other important psychological experiments that have stood the test of time.

National Hispanic Heritage Month celebrates and recognizes Hispanic American contributions to US society and culture. Designated in 1968 when Congress passed Pub. L. 90-498 authorizing and requesting the President to issue an annual proclamation of National Hispanic Heritage during mid- September. September 15th marks the anniversary of independence for the Latin American countries of Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Mexico celebrates its independence on September 16th.

President Lyndon Johnson issued the first such proclamation External in 1968. Between 1969 and 1988, Presidents Nixon, Ford, Carter and Reagan issued a series of annual proclamations designating a week in September as National Hispanic Heritage Week. In 1988, Congress passed Pub. L. 100-402 [PDF] which amended Pub. L. 90-498 and established National Hispanic Heritage Month from September 15th to October 15th. Between 1990 and 2009, Presidents George H.W. Bush, Bill Clinton, George W. Bush and Barack Obama issued annual proclamations for National Hispanic Heritage Month.

Many organizations across the federal government collaborate to highlight their services as they pertain to Latinx and Hispanic Americans.

Stonehenge’s Altar Stone came all the way from Scotland, new research shows

The central stone of the famous British monument came from 750km (465 miles) away in Scotland, and not Wales as previously thought.

At the centre of Stonehenge lies the Altar Stone, a hefty slab of sandstone whose origin and purpose have been among the famed megalithic monument’s enduring mysteries for nearly 5,000 years.

Now a new study, published in the journal Nature, has revealed that the rectangular colossus was transported from northeast Scotland by Stonehenge’s creators to Salisbury Plain in southern England, some 750km (465 miles) away.

New study suggests ocean of water lies beneath mars’s surface, would a hidden ocean on mars spur human settlement, ‘never say goodbye’: can ai bring the dead back to life, china wrestles with ‘quantity over quality’ in generative ai patents.

The stone’s geochemical fingerprint is a perfect match for bedrock found in Scotland, researchers said on Wednesday, solving one mystery but raising another: how did its prehistoric builders move the huge slab – weighing an estimated six tonnes – so far?

More recently, scientists have determined that the site’s upright sandstones came from relatively nearby Marlborough, while the bluestones arrayed near its centre came from Wales.

But the origin of the Altar Stone, a unique slab laying on its side at the heart of the circle, remained elusive.

‘Genuinely shocking’

The findings left the researchers stunned. No stone from any other monument dating to that time period is known to have been transported such a distance.

“We couldn’t believe it,” said Anthony Clarke, a doctoral student in geology at Curtin University in Australia and lead author of the study.

For more than 100 years, scientists believed the altar stone came from much closer Wales.

However tests along those lines always “drew a blank,” said Richard Bevins, a professor from Aberystwyth University, mid-Wales, and co-author of the study.

This prompted a team of British and Australian researchers to broaden their horizons – and in turn discover something “quite sensational”, he told AFP news agency.

Using chemical analysis, they determined that the Altar Stone came from Scotland’s Orcadian Basin.

“This is a genuinely shocking result,” study co-author Robert Ixer of University College London said in a statement.

The “astonishing” distance was the longest recorded journey for any stone at the time, said fellow co-author Nick Pearce of Aberystwyth University.

Whether people around 2,500 BC were capable of transporting such huge stones from Wales had already been a matter of heated debate among archaeologists and historians.

That a five-by-one-metre (16-by-three-feet) stone made the trip across much of the length of the United Kingdom suggests that the British Isles were home to a highly organised and well-connected society at the time, the researchers said.

They called for further research to find out exactly where in Scotland the stone came from – and how it made its way to Stonehenge.

To work out where it came from, the researchers fired laser beams into the crystals of a thin slice of the Altar Stone. The ratio of uranium and lead in these crystals act as “miniature clocks” for rocks, providing their age, said study co-author Chris Kirkland of Curtin University.

The team then compared the stone’s age to other rocks across the UK and found “with a high degree of certainty” that it came from the Orcadian Basin, Kirkland said.

Susan Greaney, an archaeologist at the UK’s University of Exeter who was not involved in the study, said it established the first “direct link” between southern England and northern Scotland during this time.

“The placement of this stone at the heart of the monument, on the solstice axis, shows that they thought this stone, and by implication, the connection with the area to the north, was incredibly important,” she said.

New study unveils 16,000 years of climate history in the tropical andes.

Brown University researchers highlight the roles of carbon dioxide and ocean currents as key drivers of temperature fluctuations in the tropical Andes over a 16,000 year period.

PROVIDENCE, R.I. [Brown University] — A new study that explores ancient temperatures and rainfall patterns in the tropical Andes of South America has revealed how 16,000 years of climate history in this part of the world was driven by carbon dioxide levels and ocean currents from global climate events.

Led by Brown University researchers, the study marks the first high-resolution temperature record covering the past 16,000 years in the tropical Andes and could help scientists predict and mitigate future climate impacts in tropical regions of the planet. The work is described in the Proceedings of the National Academy of Science.

“Usually when we study climate change in the past, we emphasize the Northern Hemisphere or Southern Hemisphere because of the outsized role they play in affecting climates all over the globe,” said Boyang Zhao, a scientist in Brown’s Department of Earth, Environmental and Planetary Sciences and the study’s first author. “One of the biggest questions we are getting at is what are the driving factors behind temperature history in this part of the tropics, so that we can begin to potentially apply that data and knowledge to other tropical regions.”

Along with future implications, the new study provides a unique look at the way distinct and distant parts of the world influence temperature and weather elsewhere, emphasizing how regional climates are connected to global climate changes.

“Our evidence here suggests that temperatures in this region of the world are more influenced by the Southern Hemisphere — so places like Antarctica,” Zhao said.

The study focused on an analysis of sediment samples from Laguna Llaviucu, a lake located in Ecuador’s Cajas National Park. The measurements from the sediment samples showed that temperature variations in the tropical Andes closely aligned with climate events that saw the planet’s temperatures rise and fall during the past 16,000 years.

Overall, the evidence showed that the main driver in these temperature fluctuations was the concentration of CO2. Researchers saw evidence that the tropical Andean temperatures track with Antarctic temperatures, which are mainly controlled by carbon dioxide concentrations. The findings showed that about 17,000 to 14,000 years ago, tropical Andean temperatures rose when carbon dioxide increased and that the temperatures remained relatively stable about 12,000 years ago when carbon dioxide levels remained relatively stable.

Zhao said that the findings support previous research identifying carbon dioxide as a key driver of global temperature changes since the last Ice Age.

The study also highlighted the role of ocean currents that move warm water from the tropics to the North Atlantic. During a cooling period known as the Antarctic Cold Reversal 14,500 years ago, the northward current was strengthened, causing it to transport more heat northward and cool sea surface temperatures in the south. The researchers found that this cooling effect extended to the tropical Andes.

To reconstruct past climate conditions, the researchers analyzed lipid biomarkers and hydrogen isotopes collected in 2009 from Laguna Llaviucu by scientist Mark Bush from the Florida Institute of Technology. Lipid biomarkers are chemical compounds that provide clues about past temperatures and rainfall patterns. The high-resolution data, combined with accurate dating techniques, allowed the team to create a detailed timeline of climate changes over the past 16,000 years.

According to the researchers, this is the first time organic biomarkers have been used to put together a quantitative climate history for tropical South America. It is traditionally difficult to reconstruct temperatures from the tropics.

The study also points out a number of regional differences in temperature patterns, like how the tropical Andes and Southeast Asia cooled during certain historical periods while other regions like Africa did not. The research also shows how local factors may help to counteract the global effects of rising CO2 levels by looking at differences between past temperature models and what the sediment data show.

The researchers from Brown plan to continue to explore past temperature patterns in this part of the world that historically lacks complete climate records.

“Mountain environments are some of the most sensitive regions on Earth to climate change,” said James Russell, a professor of Earth, environmental, and planetary sciences at Brown who oversaw the new research. “In fact, in the near future, high tropical mountains, such as the Andes, are predicted to experience a rate of warming second only to the Arctic, which is the fastest warming part of the planet.”

Along with Zhao and Russell, authors from Brown also included undergraduate student Aaron Freeman. This work was supported by the U.S. National Science Foundation.

Computer tablet use linked to angry outbursts among toddlers, research shows

While allowing little kids to stare at a computer screen often gives parents a much-needed respite, new research suggests cutting back on the practice, with early tablet use linked to increased outbursts later on. 

Children logging 75 minutes or more of daily screen time at 3 1/2 years old were more apt to outbursts of anger and frustration a year later, a study published in the journal JAMA Pediatrics found. 

Further, the findings  suggest a vicious cycle is in play, with little kids who were more apt toward expressions of anger and frustration at 4 1/2 years old likely to spend even more time on an iPad a year later. 

"It might allow parents to immediately avoid a temper tantrum but in the long term, repeated use of this kind of strategy does not allow children to develop strong, internal emotional regulation skills," the study's author, Caroline Fitzpatrick, a professor of child development at the University of Sherbrooke in Quebec, told CBS Evening News.

The study's findings are based on a survey of 315 parents of preschool-aged children living in Nova Scotia, Canada. Participants self-reported tablet use by their kids at 3 1/2 years of age, a year later at 4 1/2 years old, and then at 5 1/2 years, in 2022. Parents also answered standard questions to access their children's expressions of anger.

Still, some parents find a little bit of tablet time can be a big help, without causing any apparent harm.

Atlanta mother Farrah Butler occasionally allows her 3-year-old son, Oliver, to play on an iPad, particularly when she needs a break or is trying to get something done, such as cook dinner.

"The screen is helpful when you're trying to get daily tasks done, when they want you to play and you just need to take a few minutes," Butler said. She and her husband have found that Oliver and his two siblings didn't mind too much when their mobile screens were taken away. "They found other things to do with their time," she relayed.
