Psychology is an article-driven discipline, so go to the "Articles" tab for information on the best databases to use for finding articles on your topic. To find suggested sources for the course in which you're enrolled, go to the "Summer 2020 Online Courses" tab.
Please remember always to cite the source where you obtained your information, according to the rules in the Publication Manual of the American Psychological Association. For quick help, see the online guide offered by Purdue University as well as the APA's own tutorial.
