Psychological Explanations: Eysenck's Theory Flashcards
Eysenck date
1947
Eysenck proposed that personality could be represented along three dimensions
Introversion.
Neuroticism.
Psychoticism.
Introversion.
extraversion (E)
Neuroticism.
stability (N)
Psychoticism.
socialization (P)
the dimensions combine to form a
variety of personality characteristics or types
Eysenck suggested personality types are
innate and based on the nervous system we inherit
extroverts have an
under active nervous system which means they seek excitement and stimulation and engage in risk taking
neurotic individuals have a high level of reactivity in the
sympathetic nervous system
having a high level of reactivity in the sympathetic nervous system means neurotic individuals
react quickly to situations of threat
neurotic individuals tend to be
nervous, jumpy and over-anxious so their behavior is difficult to predict
psychotic individuals are suggested to have higher levels of
testosterone - they’re cold, unemotional and prone to aggression
The criminal personality type is a combination: neurotics
Neurotics are unstable and therefore prone to overreact to situations of threat
The criminal personality type is a combination: Extraverts
Extraverts seek more arousal and thus engage in dangerous activities
The criminal personality type is a combination: Psychotics
Psychotics are aggressive and lacking empathy
Eysenck saw criminal behaviour as
Developmentally immature in that it is selfish and concerned with immature gratification
Criminals are
Impatient and can not wait for things - so they are more likely to act anti socially
In the process of socialisation, children are taught to become
More able to delay gratification and more socially orientated
Eysenck believed that people with high Extraverts and Neurotics scores had
A Nervous systems that made it difficult for them to learn
As a result of having high extravert and neurotic scores
People are less likely to learn anxiety responses to antisocial impulses
A notion that personality can be measured is
Central to Eysenck’s theory
Eysenck developed the
Eysenck personality inventory (EPI)
Eysenck personality inventory (EPI) is a
Psychological test that locates respondents along the extravert and neurotics dimensions to determine their personality type
A letter scale was introduced to the Eysenck personality inventory (EPI) to
Measure psychoticism
Eysenck and Eysenck Date
1977
Eysenck and Eysenck compared EPI scores of
2070 male prisoners with a control group containing 2422 non-criminal men
Farrington et al date
1982
Farrington et al review of studies showed offenders scored high on
Psychotic but not on extravert or neurotic
Farrington et al also found little evidence of
Consistent differences in EEGs between Extraverts and introverts
Eysenck and Eysenck casts double on the
Psychological basis of Eysenck’s theory
Moffitt (1993) proposed several types of
Adult male offender
What did Moffett base his idea on?
Based on the timing of the first offence and how long the offending persists
Eysenck’s theory is
Out of step with modern personality theories
Digman date
1990
Digman’s five factor model suggests
Three additional dimensions of openness, agreeableness and conscientiousness
There may be many different types of criminal since
Extravert and neurotics aren’t the only factors that contribute
Bartolomea and Holanchock Date
1979
Bartol and Holanchock studied
Hispanic and African-American offenders in a New York top security prison
Bartol and Holanchock divided the Hispanic and African-Americans into
Six groups based on criminal history and offence
All six of Bartol and Holanchock’s groups were
Less extravert than a non-criminal control group
Bartol and Holanchock suggested that this was because the
Sample was a different cultural group from that investigated by Eysenck
Bartol and Holanchock questions the
Generalisability of the criminal personality
Eysenck’s theory assumes that it is possible to
Measure personality
Critics have said that Eysenck cannot
Reduce personality to a score from the EPI
Some people say that there isn’t even a thing such as
Personality as a stable entity - we adopt different personalities is different contexts
Eysenck’s theory recognises personality
May have a genetic basis
prisoners scored higher on
extroverts, psychotic neurotic supprting predictions of the theory
