ps ex - Eysenck's theory Flashcards
what is the general personality theory?
Eysenck (1963)
Three dimensions combine to form personality: introversion–extraversion (E), neuroticism–stability (N), psychoticism–sociability (P).
what is the biological basis of this theory?
Personality type is innate due to inherited nervous system, e.g. extraverts have underactive system so seek excitement.
what is the criminal personality in this theory?
Mostly neurotic-extraverts: emotionally unstable and overreact (neuroticism) + need arousal and enjoy danger/risk (extraversion). Also high P (aggressive, lack empathy).
what is an extravert?
underactive nervous system, seek stimulation, dont condition easily so dont learn from mistakes
low extraversion - introvert.
what is a neurotic?
high level of reactivity in sympathetic nervous system, difficult to predict.
low neuroticism - stable
what is a psychotic?
higher levels of testosterone, prone to aggression
low psychotics - sociable
what is the role of socialisation?
Neurotic-extraverts do not condition easily so do not learn to respond to antisocial behaviour by becoming anxious, as most people do.
how do you measure the traits?
Eysenck Personality Questionnaire measures E, N and P to determine type, then linked to other variables.
