Types of APA Papers

Welcome to the Purdue OWL

APA (American Psychological Association) style is most commonly used to cite sources within the social sciences. This resource, revised according to the 6 th edition, second printing of the APA manual, offers examples for the general format of APA research papers, in-text citations, endnotes/footnotes, and the reference page. For more information, please consult the Publication Manual of the American Psychological Association , (6 th ed., 2 nd printing).

Note:  This page reflects APA 6, which is now out of date. It will remain online until 2021, but will not be updated. There is currently no equivalent 7th edition page, but we're working on one. Thank you for your patience. Here is a link to our APA 7 "General Format" page .

There are two common types of papers written in fields using APA Style: the literature review and the experimental report (also known as a "research report"). Each has unique requirements concerning the sections that must be included in the paper.

Literature review

A literature review is a critical summary of what the scientific literature says about your specific topic or question. Often student research in APA fields falls into this category. Your professor might ask you to write this kind of paper to demonstrate your familiarity with work in the field pertinent to the research you hope to conduct. 

While the APA Publication Manual does not require a specific order for a literature review, a good literature review typically contains the following components:

• Introduction
• Thesis statement
• Summary and synthesis of sources
• List of references

Some instructors may also want you to write an abstract for a literature review, so be sure to check with them when given an assignment. Also, the length of a literature review and the required number of sources will vary based on course and instructor preferences.

NOTE:  A literature review and an annotated bibliography are  not  synonymous. While both types of writing involve examining sources, the literature review seeks to synthesize the information and draw connections between sources. If you are asked to write an annotated bibliography, you should consult the  Publication Manual of the American Psychological Association  for the APA Format for Annotated Bibliographies.

Experimental/Research report

In many of the social sciences, you will be asked to design and conduct your own experimental research. If so, you will need to write up your paper using a structure that is more complex than that used for just a literature review. We have a complete resource devoted to writing an experimental report in the field of psychology  here .

This structure follows the scientific method, but it also makes your paper easier to follow by providing those familiar cues that help your reader efficiently scan your information for:

• Why the topic is important (covered in your introduction)
• What the problem is (also covered in your introduction)
• What you did to try to solve the problem (covered in your methods section)
• What you found (covered in your results section)
• What you think your findings mean (covered in your discussion section)

Thus an experimental report typically includes the following sections.

• Multiple experiments (if you conduct more than one)
• Appendices (if necessary)
• Tables and/or figures (if necessary)

Make sure to check the guidelines for your assignment or any guidelines that have been given to you by an editor of a journal before you submit a manuscript containing the sections listed above.

As with the literature review, the length of this report may vary by course or by journal, but most often it will be determined by the scope of the research conducted.

Other papers

If you are writing a paper that fits neither of these categories, follow the guidelines about  General Format , consult your instructor, or look up advice in the  Publication Manual of the American Psychological Association .

When submitting a manuscript to a journal, make sure you follow the guidelines described in the submission policies of that publication, and include as many sections as you think are applicable to presenting your material. Remember to keep your audience in mind as you are making this decision. If certain information is particularly pertinent for conveying your research, then ensure that there is a section of your paper that adequately addresses that information.
