Trait Theory Chapter 11
Key Concepts • PERSONALITY TRAITS are permanent characteristics each of us has • Taken together, they make up our personality • Traits influence how we perceive the world and respond to it • Trait theorists agree on what a personality trait is • Disagree on which are most important & how they are observed • Trait theories are concerned with describing what personality is rather than where personality comes from.
Gordon Allport • Theory starts with common terms used to describe people • Honest, dominant, outgoing, etc. • Three categories of traits • Stronger and most often expressed weaker, less commonly expressed
Traits • Cardinal Traits • Extremely strong personality characteristics • Expressed in almost all activities • “Ruling Passion” • Quite rare • Hitler; Mother Teresa • Central Traits • Highly characteristic; apply to most situations • Described by 5-10 of them • Contains what we think of as traits • Optimistic, decisive, etc.
Traits cont. • Secondary Traits • Weakest, least characteristic • Appear only in certain situations • Do not describe someone well • Aggressive only when others attacked • Nomotheitc approach • Study large groups of people searching for general laws • Idiographic approach • Studying individuals to understand uniqueness
Hans Eysenck • Factor Analysis • Describes the extent to which personality variables are related • There are only 2 dimensions necessary to describe personalities
Dimensions Extraversion Emotional Stability Opposite: emotional instability How much a person is affected by feelings • Opposite: Introversion • Scaled from very outgoing to very quiet
Raymond Cattell Surface Traits Source Traits Underling trait Produces behaviors we can see Source trait from example: submissive 16 total source traits • Describe regular behavior • Friend constantly gives in, never takes a stand • Traits cluster together because of underlying trait
The Five-Factor Model • Twin studies have shown that five personality factors seem to be inherited • Extraversion, Agreeableness, Conscientiousness, Emotional Stability, Openness to experience • Found across cultures • Tend to be relatively set throughout life • Established early, set by our 20s
Effects of the Environment • Personality theorists believe ~50% of personality is heredity • Environment is not strictly “good” or “bad” • Seemingly same environment vastly different for different kids • Reacting differently to the same things • Example: Birth order • Interactions with siblings carry more weight on our personality than interactions with parents
