AP PSYCHOLOGY

Detailed explanation-1: -Cattell (1957) identified 16 factors or dimensions of personality: warmth, reasoning, emotional stability, dominance, liveliness, rule-consciousness, social boldness, sensitivity, vigilance, abstractedness, privateness, apprehension, openness to change, self-reliance, perfectionism, and tension ([link]).

Detailed explanation-2: -Types and Traits Cattell considered types to fall into one of five principal categories: temperamental characteristics, interests and character, abilities, disposition, and disintegration and disease processes.

Detailed explanation-3: -According to Cattell, traits and types are not fundamentally different, but rather opposite extremes of the same statistical measures. The fundamental, underlying traits are known as source traits. Source traits often combine and/or interact in ways that appear, on the surface, to indicate a single trait.

Detailed explanation-4: -The five broad personality traits described by the theory are extraversion (also often spelled extroversion), agreeableness, openness, conscientiousness, and neuroticism.
