These resources refer to the current 7th edition of the Publication Manual of the American Psychological Association (APA). Starting in January 2020, we recommend using these 7th edition resources unless your instructor specifies that they will be using the 6th edition in their class.
A great way to find articles on your topic is to look at the reference list of a relevant article you have already found. Articles cited by an author are often closely related to the same topic.
Using PsycINFO, you can find related articles by looking for the Cited References and Times Cited in this Database links on an article record specifically.
Using Google Scholar, look for the Cited by link below the title and description. Related Articles will also retrieve related articles. Usually the first few articles retrieved with the Related Articles function will be the most strongly related (results may vary).
