What Psychology Studies

This lesson defines what psychology studies and sets the scope for the rest of the course. Psychology is the scientific study of behavior and mental processes, including how people think, feel, learn, remember, and act in different situations. Students will distinguish psychology from related fields, understand why context and evidence matter, and see how the field balances individual experience with broader patterns.

The lesson also introduces the idea that psychology is not one theory but a discipline with multiple lenses. That foundation will help students understand why later lessons explore different foundational theories and how each one explains human behavior in a distinct way.
