The APA (American Psychological Association) referencing style is used by professionals in psychology. The latest edition of the APA guide is the 7th.
In the APA style of referencing, you acknowledge the source within the text by citing the author’s last name and date of publication in parentheses, e.g. (Jackson, 2021). You also provide full details of each item in an alphabetical reference list at the end of your assignment. You may also include a bibliography, although it is not a necessity.
