Personality
Personality describes the behavioral, cognitive, and emotional patterns that make up a person’s unique adjustment to life. Personality is relatively stable, but can change over time due to experiences and developmental processes. Although there is no consensus definition of personality, most theories in personality focus on traits, motivation, skills, and identity.
Research in personality psychology generally attempts to explain the characteristics of a person that underlie differences in behavior. Personality characteristics are related to many life outcomes, such as work and relationship success, to mental health, well-being and longevity.
