Cattell's developmental theory

Cattell's developmental theory suggests that human personality is shaped by both inherent traits and life experiences over time. He identified two main types of traits: "ability" traits, which include skills and intelligence, and "temperament" traits, which influence how we react emotionally. These traits develop and change through stages of life, influenced by age, environment, and personal growth. Essentially, Cattell believed that understanding these traits and their development helps explain why individuals behave differently across different stages of life. His work emphasizes that personality is dynamic and adaptable, molded by both biological factors and life circumstances.
