There are two principle ways to read a Psychology research article. Psychology articles generally follow this outline:
1. Read the article from beginning to end. If you are familiar with the topic and the study methodology, this will probably work fine.
2. Generally, the better option is to read the introduction and statement of the problem followed by reading the discussion and/or conclusions of the study. This helps to create a road map, so that the middle sections of the article are more easily grasped. This is especially true if you are unfamiliar with the topic or methodology employed. The middle sections of a research article can be quite technical and difficult to understand if you don't where the author(s) is going with the research.
