APA Style uses the author-date citation system in which a brief in-text citation directs readers to a full reference list entry. In-text citations appear within the body of the assignment (or in a table, figure, footnote, or appendix) and briefly identifies the cited work, within the sentence, by its author and date of publication. This enables readers to locate the corresponding entry in the alphabetical reference list at the end of the paper.
You cite each work every time you refer to it in your paper, unless citing a single work in a long paraphrase.
For more information on in-text citations please see page 7-11 of the referencing guidelines.
For information on citations for long paraphrasing (ie. an entire paragraph has key points from the same source) please see the recorded webinar from PSI CHI (2022) starting from time stamp 32:48.
