Which theory of personality includes traits such as openness and conscientiousness?

The Big Five Personality Traits theory is the model that encompasses the traits of openness and conscientiousness, among others. This theory posits that personality can be described using five broad dimensions: openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism.

Openness reflects a person's willingness to engage with new ideas, experiences, and imaginative concepts, while conscientiousness relates to an individual's level of organization, dependability, and goal-oriented behavior. These traits are foundational to the Big Five model and contribute significantly to personality psychology.

In contrast, Freudian Theory focuses on the significance of unconscious drives and conflicts, emphasizing fears, desires, and childhood experiences rather than specific traits. The Humanistic Approach prioritizes personal growth and self-actualization, concentrating on individual experiences and emotions rather than structured personality dimensions. Cognitive Behavioral Theory is rooted in understanding how thoughts influence behavior, thus it also does not define personality in terms of stable traits.

The specificity and empirical support behind the Big Five traits make this theory foundational in understanding personality in a systematic manner.
