The Key Terms section is your go-to glossary for every major concept covered in AP Psychology. I created it to make studying easier and more efficient by compiling all the essential vocabulary from each unit in one organized place. These are the terms you’ll see over and over, in class discussions, quizzes, practice tests, and most importantly, on the AP exam.

Each definition is written in clear, simple language to help you actually understand the term, not just memorize it. I pulled directly from our class materials, lectures from Mr. Matthew Lopez, and official AP Psych content to make sure everything is accurate and aligned with the College Board’s expectations.

Whether you’re making flashcards, reviewing for a unit test, or prepping for the big exam, this section can help you lock down the language of psychology. Mastering these key terms is one of the fastest ways to boost your confidence and your score.
