Literature Review

This guide provides support for conducting literature reviews.

What is a Literature Review?

A literature review is an thorough and up-to-date overview of existing research about the topic being studied.  The literature may come from books, articles, documentaries, interviews, critical reviews, DVDs, or other formats. 

It's a review because it usually contains a summary, synthesis, or analysis of the central arguments in the existing literature on the topic.  A literature review does not present an original argument, but instead presents the arguments of others. The sources are the main focus in a literature review and the author summarizes the arguments or ideas of others. You should include only the most relevant sources on a topic.

The literature review may also include gaps in the literature, identifying areas where further research needs to be completed.

 

What is the purpose of a literature review?

A literature review can have several purposes.  It can:

  • summarize the existing research on a particular topic
  • introduce the important research on a topic
  • point out contradictory or controversial studies or methodologies
  • raise a question or highlight an issue for further study
  • help to contextualize the current research

APA how to cite AI 2024

https://apastyle.apa.org/blog/how-to-cite-chatgpt - see chapter 10 APA manual
Quoting ChatGPT’s text from a chat session is more like sharing an algorithm’s output; thus, credit the author of the algorithm with a reference list entry and the corresponding in-text citation.

OpenAI. (2023). ChatGPT (Mar 14 version) [Large language model]. https://chat.openai.com/chat

In text:

  • Parenthetical citation: (OpenAI, 2023)
  • Narrative citation: OpenAI (2023)


If you’ve used ChatGPT or other AI tools in your research, describe how you used the tool in your Method section or in a comparable section of your paper.
For literature reviews or other types of essays or response or reaction papers, you might describe how you used the tool in your introduction. In your text, provide the prompt you used and then any portion of the relevant text that was generated in response.

You may also put the full text of long responses from ChatGPT in an appendix of your paper or in online supplemental materials, so readers have access to the exact text that was generated. It is particularly important to document the exact text created because ChatGPT will generate a unique response in each chat session, even if given the same prompt. If you create appendices or supplemental materials, remember that each should be called out at least once in the body of your APA Style paper. So for example:

"When given a follow-up prompt of “What is a more accurate representation?” the ChatGPT-generated text indicated that “different brain regions work together to support various cognitive processes” and “the functional specialization of different regions can change in response to experience and environmental factors” (OpenAI, 2023; see Appendix A for the full transcript)."
_______________________________________________
APA statement of use of AI in scholarly materials: https://www.apa.org/pubs/journals/resources/publishing-policies?tab=4

For this policy, AI refers to generative LLM AI tools and does not include grammar-checking software, citation software, or plagiarism detectors.

  • When a generative artificial intelligence (AI) model is used in the drafting of a manuscript for an APA publication, the use of AI must be disclosed in the methods section and cited.
  • AI cannot be named as an author on an APA scholarly publication.
  • When AI is cited in an APA scholarly publication, the author must employ the software citation template, which includes specifying in the methods section how, when, and to what extent AI was used. Authors in APA publications are required to upload the full output of the AI as supplemental material.
  • The authors are responsible for the accuracy of any information in their article. Authors must verify any information and citations provided to them by an AI tool. Authors may use but must disclose AI tools for specific purposes such as editing.
  • No submitted content may be entered into generative AI tools as this violates the confidentiality of the process.
