Resources in psychology.
"I'm interested in the topic of dreaming, and I'd like to find an article on it. I'm not a psychologist, so I don't want anything that is too technical. Where can I find some easy-to-read articles that discuss research and topics in this area of psychology?"
APA receives many requests from individuals looking for general information on psychological topics. These topics include a wide range of issues, from ability tests for employees to research on drugs and the brain, school violence, the impact of AIDS on family members and the ways in which children learn. A variety of resources about psychology are available on the Internet or at any library, including books, journals, newspapers, pamphlets and electronic resources.
Many library resources may be available without leaving your home or office. Your topic can be easily located using the online catalog and Web-based indexes or subject guides and databases. The databases are generally listed by subject category and will help you find resources in a wide array of fields, including psychology.
You may want to review the following consumer health resources to familiarize yourself with the topic including Health and Wellness Resource Center, Health Source: Consumer Edition , WebMD . To consult the resources used by the medical research community, you will be able to access Medline, an abstracts database or PubMED , a database of publicly funded articles. These authoritative sources are produced by the U.S. National Library of Medicine. Indexes such as the Reader's Guide to Periodical Literature may also be available to point you to popular sources of information such as magazines and newspapers. A number of electronic resources may be available to you through your school or public library website; consult your reference librarian for step-by-step instruction.
Most large newspapers, such as The New York Times , The Washington Post and The Wall Street Journal are searchable on the Internet. Access to an archive of previously published articles may be available for a nominal fee.
A topic search using one of the well-known Internet search engines, such as Google , Yahoo or Bing may also provide access to information from a variety of resources. Specific organizations that publish information on your topic area generally make information available on their website.
The American Psychological Association website is also a source for authoritative information and research tools in psychology. It also includes topics of interest to a wide audience such as ADHD , bipolar disorder , eating disorders , gun violence , learning and memory , PTSD , and more.
Note: Just because you find information does not mean that it is accurate. Be sure to consider the source of the information and its currency before using it for research.
APA Resources
APA often receives calls from students preparing for their first research assignment. Often instructors will suggest that classes visit the APA website , which is an excellent starting point and provides authoritative information on current topics and issues , press releases , reports , and position papers that can be helpful in selecting your topic. You can access both free and paid resources at the APA website.
Most major university libraries provide electronic access to bibliographic and full-text databases produced by APA. These resources include APA PsycInfo ® , an abstracts database; APA PsycArticles ® , full text of APA journal articles; APA PsycBooks ® , full-text books, book chapters and entries from the Encyclopedia of Psychology ; APA PsycExtra ® , research from outside the peer-reviewed publication; APA PsycTests ® , psychological tests, measures, scales, surveys and other assessments; and APA PsycTherapy ® , videos featuring therapy demonstration. APA also publishes a series of handbooks that provide in-depth information on a number of topics such as research methodologies.
These authoritative sources are used by research professionals, clinicians and mental health professionals worldwide. Some library catalogs also provide links to the full-text journal articles, and books or book chapters in the databases.
The databases let you search by general topics or keywords. You can consult the Thesaurus of Psychological Index Terms ® to find the most current terms in the literature. Consult your librarian for more information.

Peer Review & Scholarly
- Peer Review
What does peer reviewed mean?
Peer review is an editorial process whereby experts in a given field help judge the value of a relevant work or ideas that they were not part of creating. The primary function of peer review is gatekeeping—selecting the best from a pool of submissions. It also serves, however, as a source of constructive criticism, whereby expert feedback by peers can be taken into account to improve ideas, research proposals, and papers.Source: Britannica Academic
Peer reviewed journals and refereed journals are interchangeable terms = same meaning.
Most library databases provide a check-box to limit your search result to articles that are Scholarly and/ or Peer Review.
- Popular Literature vs. Scholarly Peer-Reviewed Literature: What's the Difference?
What are scholarly articles?
Although peer-reviewed journals are always scholarly in nature, scholarly journals are not always peer-reviewed. Scholarly journals are research focused, reporting results of original research and experimentation. The articles in these journals are heavily cited in the form of either footnotes or bibliographies, and written by, and addressed to, experts in a discipline. However, whereas peer-reviewed journals require a strict "peer-approval" for publishing, a scholarly journal that is not peer-reviewed only requires the approval of an editorial board.

The entire process of writing a psychology research paper can be stressful for college students. Sometimes, just picking a topic can seem daunting! Once you settled on a subject, actually finding sources to document your ideas and support your claims can be just as difficult. Where exactly should you look to find quality and reputable sources for your psychology research papers?
When you first start researching a subject, figuring out where to begin can be a real challenge. Where should you look for information? What kinds of sources are available? How do you decide which sources to include in your paper? While there is no simple way to make the research process fast and easy, there are steps you can take to ensure that you find the information you need.
If you are working on a psychology paper and are struggling to find sources, consider following the steps below.
1. Start by Choosing a Strong Topic
A good research topic is neither too broad nor too narrow. If you choose a subject that is too general, you will probably find yourself overwhelmed by information. Choosing a subject that is too specific leads to the opposite problem; not being able to find enough information to write about.
For example, if you chose "drug abuse" as the topic for your research paper, you would quickly find that there is no way to fully cover the subject in the limited number of pages you have to write. However, you can easily narrow this overly broad topic into something that will work.
Start by thinking of some questions that you might have about drug addiction . "How does drug use impact the health and well-being of college students ?" is an example of a research question that would yield plenty of information without being overwhelming.
2. Find Basic Background Information
The next step is to search for some basic background information on the topic for your psychology paper. At this stage, you're mostly looking for introductory information, but many of the sources you browse at this stage may also contain information on more in-depth sources.
For example, you might look through encyclopedias, online reference sites, lecture notes, supplementary course readings, or your own class textbooks for information on your topic. Pay careful attention to any sources that are cited in these readings and make note of these references so you can locate them in your school's library or online during the next phase of the research process.
Sometimes finding sources involves following a trail of sources starting with general information until you drill down to more specific references.
3. Use Library Catalogs to Search for Books
The next step is to pay a visit to your university library. The basic background research you did in the previous step should have offered some hints on what you need to look for. If you're still struggling, be sure to ask the librarian for assistance. Library staff are trained and skilled at locating all kinds of information.
If you are a distance education student, don't fret; there are still plenty of ways to access library resources. Start by checking with your school to see what type of distance resources they offer to online students. In many cases, you can access the materials you need via an interlibrary loan in which your local library is able to borrow books or other documents that are owned by another library.
Once you've located some books on your topic, spend some time browsing through the references listed in each book. For each and every source you find, think of the bibliography as a guide to further sources of information that might be helpful.
4. Utilize Online Databases to Find Periodicals
The next step is to start looking through online databases such as PsycINFO, PsycNET, and EBSCOhost in order to find journal articles on your topic. While some of these can be accessed online from your home computer, you might have to visit your library in order to access your school's subscription to certain databases.
In some cases, full-text versions of articles might be available online, but you will probably have head to the stacks to look up hard copies of many articles in your university's library. If you're not sure how to access these databases or how to perform a search, be sure to seek assistance from a librarian.
5. Search for Online Sources
The Internet can be a great way to find sources for your psychology research paper, but you need to know how to use it effectively. Start by checking with your instructor to find out what kinds of online sources can be used as references. Some instructors do not allow students to use any online references, while others allow only certain types. Online journal articles, newspapers, magazines, forums, blogs, and informational websites are all possible sources of different types of information.
A number of professional journals offer free access to full-text articles .
Even if your instructor does not allow online sources, the Internet can still be a useful tool. Online articles often contain information about books, journal articles or other offline sources that you are allowed to use in your paper.
6. Carefully Evaluate Each Source
Once you have assembled a good selection of possible sources, the next step is to start carefully evaluating each one to determine if it is credible and appropriate for your paper. Evaluating your sources involves a number of things, including noting the age of the information, the author, and the publisher.
Evaluating online sources can be a bit trickier. While there is a lot of great information out there on the web, there are also plenty of websites that are poor quality, misleading or downright incorrect.
7. Create a Working Bibliography
Even if your instructor does not require you to write and hand in a bibliography, creating one can be a very helpful part of the research process. A bibliography is basically a list of all the sources that you might use in your paper. In addition to listing all of the sources you've collected, consider adding a brief annotation to each entry that describes what the book or article is about. As you begin outlining your paper, refer back to your working bibliography in order to determine which sources to use in order to back up your arguments, analysis, or claims.
- Work from the general to the specific. Start with general resources like encyclopedias, and then start working your way down to more specific references like journal articles .
- Keep track of where you got your information! Maintain careful notes or a working bibliography in order to ensure that each source is properly cited in your paper.
- Don't be afraid to ask your librarian for help. When you talk to a librarian, offer details about the specific research question or thesis of your paper. Your librarian will be better able to help you find great sources if you provide detailed rather than general information about what you're looking for.

A Word From Verywell
While finding sources for your psychology papers can certainly be challenging at times, breaking it down into a step-by-step process can make it a lot less daunting. Most importantly, don't be afraid to ask your course instructor or university library staff for help. Your teacher might be able to point you towards some sources of background information, while a librarian can aid you in searching and locating source materials related to your topic.

Boolean Operators
Many catalogs and databases allow the user to put a search string together using the boolean operators AND, OR, or NOT.
- AND - combines search terms so that each search result contains all of the terms. For example, stereotyping AND prejudice finds articles that contain both terms .
- OR - combines search terms so that each search result contains at least one of the terms. For example, stereotyping OR prejudice finds results that contain either term .
- NOT - excludes terms so that each search result does not contain any of the terms that follow it. For example, stereotyping NOT prejudice finds results that contain the term stereotyping but not the term prejudice .
In many catalogs and databases, truncation is represented by an asterisk ( * ). To use truncation, enter the root of a search term and replace the ending with an *.
For example, type behav* to find the words behav e , behav ior , behav iour , behav ioral , behav iorism , etc..

The advent of the internet has changed the way students go about conducting academic research. Before online research, students had to make the trip to their university library; comb through the stacks of physical research materials or microfiched content; read through the sources for relevant information; and manually include quotations, citations, and bibliographical entries. The internet has enabled students to access research materials digitally from anywhere in the world. Researchers can zero in on the content most pertinent to their work and automatically generate citations and bibliographies. The internet has made academic research and manuscript construction unbelievably faster and more efficient, resulting in higher-quality work.
Though online research offers many benefits, students may encounter significant drawbacks. Academic journals and books go through editing and review to vet the contents for reliability and accuracy; however, anyone can post something on the internet. As a result, researchers must learn how to discern a credible source from a non-credible one. Additionally, the wealth of information available online can make students feel overwhelmed about where to start.
The research methods in this psychology study guide can help students learn how to conduct online research. The guide includes information on search tools, strategies, and accuracy.
Methods of Psychological Research
There are several methods for conducting research in psychology. The particular type a researcher chooses often depends on the type of data they wish to obtain and whether this data should be qualitative or quantitative. Researchers can then determine whether they will base their study on descriptive, correlational, or experimental research. From there, they decide which methods of data collection best suit their study.
The following section provides an explanation of these types of data, research, and collection methods. Students conducting online research may find that they lean heavily on descriptive and correlational research. Students also often use case studies and archival data collection. No matter your preferred methods of psychological research, online sources usually provide enough data for students' research papers and literature reviews.

Quantitative Data
Quantitative data is obtained through research based on a mathematical model and statistical inferences. Researchers manipulate variables to determine causal relationships. Quantitative data includes numerical values, percentages, and statistics.
Qualitative Data
Qualitative data uses non-numerical data such as personal accounts, descriptions, observation, and interviews. This method of research often studies behavior in a natural setting.
Psychological Research Methods
Correlational research.
Correlational research is a form of non-experimental research that studies the relationship between two factors. In this method, the researcher does not manipulate any variables. This method of data analysis can help identify whether and how two factors may be associated with each other.
Descriptive Research
Descriptive research uses methods such as case studies, observation, and surveys to build an assessment of target cognitions or behaviors. Researchers do not manipulate variables or identify correlations. Instead, they describe current circumstances in order to gather information for later study.
Experimental Research
Experimental research develops more definitive conclusions about causal relationships. Researchers manipulate an independent variable and measure the effect it causes on a dependent variable. However, some variables cannot be experimentally controlled in a realistic setting, especially in the field of psychology.
Data Collection Methods
Archival data collection refers to the review of pre-existing materials or secondary sources. Researchers consult data that others have collected in order to answer questions relevant to the research subject. Researchers also use archival data to construct an understanding of a phenomenon that may require further study in the form of a direct experiment.
Case Studies
Content analysis.
Researchers in psychology frequently use content analysis to quantify findings from qualitative research. The analyst develops coding units to identify and track data points of interest. For example, content analysis may document the number of positive versus negative signifying words from a subject's qualitative response to a stimulus.
Experience Sampling
Experience sampling relies on self-reporting from participants. Participants describe their subjective perception of the study's focus. Participants may document their experiences at the request of a researcher, at pre-set intervals, or each time they encounter a specific stimulus.
Experimental Psychology
Experimental psychology endeavors to answer a theoretical question using the scientific method. In general, researchers begin with a question, propose a hypothesis, and develop an experimental study to prove or disprove their hypothesis. Usually, researchers manipulate a particular variable in a controlled setting in order to determine its effect.
Participants in a survey answer questions that may be objective, such as demographic information, or subjective, such as opinions on a topic. Surveys may come in the form of questionnaires or structured in-person interviews.
Using Google for Online Research
A simple Google search yields a plethora of information, but not all of it is reliable, applicable, or relevant to students' research. Altering search engine settings can help filter out unreliable sources and provide you with search results that are more relevant to your topic. The following section outlines some ways you can tweak your searches to net the type of results you want. We use Google for these examples, as it is the most commonly used search engine.
Refining Your Search Results
Combing through a seemingly interminable list of websites to find the information you need is a painstaking and inefficient endeavor. In order to narrow down your search results and focus on sources that fit your needs, you can take advantage of several tools Google offers. Search shortcuts allow you to target specific search results. These symbols or words allow you to indicate precisely which phrases or keywords you would like to include or exclude from your results. Shortcuts can also help you search for results on a particular site or related pages.
Site search allows users to search within a particular domain. To perform this function, simply type "site:" (without quotation marks) followed by the domain you want to search within. Note that there should be no spaces between "site:" and the domain name that follows. You can add a keyword before the site search to find information about a specific topic within that domain. For example: "psychology certification" followed by "site:apa.org." This will bring up information about psychology certification on the official website for the American Psychology Association. Using the site function, you can filter results to a particular class of site (such as .edu, .gov, .org).
You can use also the advanced search function to refine your searches without shortcut text. Advanced search allows you to add filters to control for the types of results you get, such as articles published within a certain timeframe.
Google Scholar
Students conducting psychological research online can also benefit from using Google Scholar. This tool allows you to limit your search results to scholarly sources. These sources may include articles, theses, books, and court opinions. Results from academic journals, universities, and professional societies have been vetted by their respective publishers and are highly likely to be reliable sources.
Search results from Google Scholar are sorted by relevance and ranked according to where they were published, who they were written by, and how frequently and recently they have been cited in other academic works. Information about the origins and credentials of your search results can help you to ensure your sources are as reputable and accurate as possible.
Additionally, students can set up their Google Scholar Preferences to access resources available through their college or university library. Patrons of a particular library can provide their login information and indicate that their library's resources are to be included in Google Scholar search results. The Google Scholarship Search Tips page features more details on getting the most out of Google Scholar.

Evaluating Sources
Since the internet features hundreds of both reliable and unreliable sources, it is important to screen your sources to ensure the research is accurate and dependable. Determining whether a source provides helpful and relevant information can seem confusing. However, you can analyze certain aspects of a piece to determine its accuracy. Check whether your source has a qualified author, honorable purpose, professional appearance, objective tone, current data, and relevant links. The following list features tips from Georgetown University and the University of Chicago Press .
- Who Is the Author? When evaluating a source, you should first identify the author. Search their name and try to determine any credentials that could indicate their expertise or qualifications on the subject.
- What Is Its Purpose? Once you have determined the author, look for any clues as to the purpose of the writing. Check any affiliations the author has with the sponsor of the source. You may be able to ascertain the author's motive or the intended audience of the piece.
- Does It Look Professional? The overall appearance of the site may provide you with some information about its reliability as a source. An updated and well-constructed site looks clean and organized, and does not contain spelling or grammatical errors. The page should not contain profanities. Look for coherent, concise, and professional language.
- Is It Objective? An objective source relies on facts and does not use emotionally suggestive language that indicates bias. An appropriate source does not serve as propaganda, but rather attempts to present both sides of the issue at hand. If an author makes a judgement, it should rely on sufficient, impartial evidence.
- Is It Current? Make sure your information is current as possible so any conclusions you draw from your findings are still relevant. Check data reports and statistics for the year of publication. You may also ascertain when the website was last updated.
- What Sites does it Link to? Lastly, take some time to review the citations your source provides. Make sure that the author's information comes from reputable, relevant sources. You may follow these links to ensure that they are still active and up-to-date.
Organizing Your Research
Finding, managing, and organizing sources for a research paper can seem like a daunting task. A disorganized research process and haphazard filing system can result in wasted time and a sloppy paper. Some forethought and a methodical approach may help you save time and work more efficiently. The following list provides some tips for organizing your research.
Use Reviews and Abstracts: Reading reviews and abstracts for academic papers and journal articles can help you quickly evaluate a source. If the abstract does not contain relevant information, you can avoid reading the full text.
Follow the Trail to its Source: When you find an article you think may be a good source for your research, follow the links provided in the citations. This may help you identify the original data, evaluate credibility, and find additional sources.
Stick to One Topic at a Time: In order to avoid distraction and disorganization, stick to one topic at a time. Make sure you address each one sufficiently.
Bookmark Folders: It may be helpful to create individual bookmark folders for each topic or section in your research paper. This way, you can find the right source when you need it.
Complete the Bibliography as You Go: Instead of waiting until you've finished writing the body of your paper to craft your bibliography, add citations as you go. This may help streamline the process.
Online Tools to Manage Your Research
- EasyBib: EasyBib is an app that creates citations for the bibliography of your research paper. You can select the citation style required for your paper and input your source information by book title, ISBN, or by scanning the barcode and the app will automatically generate an accurate citation.

- Zotero: Zotero automatically searches the web for material relevant to your saved selection. Users can create instant citations and bibliographies, and easily collaborate with colleagues.
Citing Online Resources for Psychology Students
Students and researchers use many different citation styles and writing formats. The style you use generally depends on the subject about which you are writing. Students conducting online psychology research studies usually use APA Style . Most science and social science disciplines follow this style. When writing research papers and creating presentations, psychology students should expect to follow APA's general format and citation rules.
Each type of source material requires a different citation format. It can be confusing for students to try and figure out how to cite their various sources. The following section provides examples of some common sources psychology students might cite. The Purdue Online Writing Lab offers excellent resources for students who need information on how to cite various sources in their academic papers.
