Psychology is the field that studies the mind and behavior. It’s the scientific investigation of mental processes—things like thoughts, feelings, perceptions, and memories—and how these mental states influence how people act in different situations. Researchers in psychology seek to understand why we think, feel, and behave the way we do, using experiments, observations, and assessments to uncover patterns and causes that connect mind and action.

Other disciplines focus on broader or different aspects: sociology looks at how people interact within societies and social structures, anthropology studies humans across cultures and time, and economics examines how people make choices about resources and production. While these areas can intersect with psychology, psychology is the one that centers specifically on the mind and behavior.
