Here is an excellent resource for helping you figure out MLA and APA formatting. Keep in mind that you may not need all of the formatting explained on the site (for example, you may or may not need an abstract section for your psychology paper). Check with your teacher or professor to make sure you know what is required.

Most of the time you will need to use proper formatting for all in-text citations (all direct quotes you got from somewhere else, as well as all paraphrases or summaries you made of someone else’s material), and also a bibliography at the end of your paper (called works cited, or references).
