In an APA paper, what is the purpose of the literature review section?

The literature review section in an APA paper serves the crucial function of summarizing and critically analyzing previous research relevant to the topic being studied. This section provides context for the current study by highlighting existing theories, findings, and gaps in the literature. It allows the author to position their research within the broader academic conversation, demonstrating how their work builds upon or differs from previous studies. By critically evaluating prior research, the literature review not only informs the reader about what has already been investigated but also justifies the need for the new study, outlining why it is significant and necessary. In doing so, it effectively establishes a foundation for the research questions or hypotheses that will be explored in the paper.
