Lecture Nov 8 Flashcards
Hans Eysenck’s theory of personality
interested in the STRUCTURE of personality
employed FACTOR ANALYSIS to identify SUPERTRAITS
Eysenck’s 3 basic personality dimensions
- extraversion-introversion
- neuroticism
- psychoticism
Eysenck’s personality divisions
specific response level (SR)
habit response level (HR)
trait level (TL)
super trait (ST)
Eysenck’s INITIAL factor analysis research yielded…
2 basic dimensions
a) extraversion-introversion
b) neuroticism
are Eysenck’s personality dimensions dependent?
no, they’re independent
means that scoring high/low on one won’t predict one’s score on another
neuroticism poles
UNSTABLE (neurotic)
STABLE
extraverts are
outgoing, impulsive, uninhibited, sociable
introverts are
quiet, introspective, reserved, distant except to intimate friends
people high on neuroticism are
unstable or highly emotional
easily upset and angered
people low on neuroticism are
less prone to emotional swings
psychoticism
3rd super trait found by Eysenck
high end: egocentric, aggressive, impersonal
Eysenck’s arguments for biological basis for personality
- CONSISTENCY of extraversion-introversion over time
- CROSS-CULTURAL research indicates 3 dimensions of personality
- GENETICS play vital role in determining a person’s PLACEMENT on the personality dimensions
2 physiological diffs that back the biological basis for personality
- sensitivity to stimulation
- sensitivity to reinforcement
sensitivity to stimulation
introverts and extraverts DIFFER in how their BRAINS respond to EMOTIONAL stimuli
introverts are QUICKLY AROUSED when exposed to external stimulation
sensitivity to reinforcement
behavioural approach system (BAS) and behavioural inhibitory system (BIS)
reinforcement sensitivity theory
