In this activity you will explore how psychologists draw solid conclusions from the complex and often ambiguous phenomena they study -- how you think, feel, and behave.

To begin, imagine you are a research psychologist. You will learn about and then put into practice some of the key terms and concepts you will need to master if your research is to succeed. Even if you never conduct your own research, mastering this information can help you become a wiser consumer, as you assess research-based claims that you confront in everyday life.

Begin by exploring investigation.
