what are the five dimensions of personality according to the trait theory?
The Five-Factor Theory of Personality. Both Cattellâs and Eysenckâs theory have been the subject of considerable research. This has led some theorists to believe that Cattell focused on too many traits, while Eysenck focused on too few. As a result, a new trait theory often referred to as the Big Five theory emerged. This five-factor model of personality represents five core traits that interact to form human personality. 1  While researchers often disagree about the exact labels for each dimension, the following are described most commonly: 2  Extraversion. 3  Agreeableness. 4  Conscientiousness. 5  Neuroticism. 6  Openness.
