Personality is defined as the set of habitual behaviors, cognitions and emotional patterns that evolve from biological and environmental factors. While there is no generally agreed upon definition of personality, most theories focus on motivation and psychological interactions with one's environment.

Trait-based personality theories, such as those defined by Raymond Cattell define personality as the traits that predict a person's behavior. On the other hand, more behaviorally based approaches define personality through learning and habits. Nevertheless, most theories view personality as relatively stable.

The study of the psychology of personality, called personality psychology, attempts to explain the tendencies that underly differences in behavior. Many approaches have been taken to studying personality, including biological, cognitive, learning and trait-based theories, as well as psychodynamic, and humanistic approaches.

Personality psychology is also divided among the first theorists, with a few influential theories being posited by Sigmund Freud, Alfred Adler, Gordon Allport, Hans Eysenck, Abraham Maslow, and Carl Rogers. The trait-based approach has yielded multiple conceptions of personality, including a number of five-factor models, Eysenck's traits, Cattel's traits and Cloninger's temperament and character traits.
