Forensics: Eyesnick's theory Flashcards
What is Eyesnick’s recipe for the ciminal personality
- Extraversion + Neuroticism + Psychoticism = the criminal personality
What is the biological explanation for Extraverts
- Have an under active nervous system, so constantly seek excitement and risk-taking behaviours.
What is the biological explanation for introverts
- (overactive nervous system) so withdraw from too much stimulation.
What is the biological explanation for neuroticism
- linked to instability in the sympathetic nervous system (if high neuroticism).
What is the biological explanation for psychotism
- higher levels of testosterone.
What is the criminal personality
- will score highly in psychoticism.
- Neurotic-extravert personality type.
- More likely to commit crimes based on emotion and will seek dangerous activities.
- neuroticism = good indicator of criminal behaviour in older people.
- Extraversion = younger people.
What is the process of socialisation
- children are taught to be able to delay gratification and become more socially oriented.
- Primarily taught through conditioning: when children act in an immature way, they are punished.
- They come to associate anxiety with antisocial behaviour.
- Esyneck believed that people with high Extraversion and Neuroticism scores cannot be conditioned easily = act antisocially.
- concern with immediate gratification -> developmentally immature.
List the evaluations for Eysenck’s personality theory
Positive:
- Supporting evidence
Negative:
- Focus on a single criminal type
- Cultural bias
- Limited by biological basis
(+) Explain how there is supporting evidence for Eysenck’s theory (Eysenck and Eysenck)
- (Eysenck and Eysenck)
- Compared 2070 male prisoners scores on EPI with 2422 male controls.
- were sub-divided into age groups 16-69 years
- Across all age groups prisoners recorded higher scores than controls for Psychoticism, Extraversion and Neuroticism.
(+) explain how there is supporting evidence for Eysenck’s theory (Rushton and Christjohn)
- Rushton and Christjohn (1981) compared E, N and P scores with self-reports of delinquency in children and students.
- High levels of delinquency correlated with higher E, P and N scores
(-) Explain how Eyesnyck’s theory on focuses on one single criminal type (Digman 5 factor model)
- Criticised for focusing on a particular criminal personality type.
- Digman (1990) - created a Five factor model: updated model of personality - included further dimensions of openness, agreeableness and conscientiousness.
(-) Explain how Eyesnycks theory displays cultural bias (Bartol and Holanchock)
- Studied Hispanic and African-American prisoners in a high-security prison.
- 6 groups – based on criminal history.
- Compared against a non-criminal control group.
- All found to be less extraverted than a non-criminal control group.
(-) Explain how Eyesnycks theory mismeasures personality (Mischel)
- Personalities are not stable, set in stone, entities that can be tested.
- Not reducible to a score -> reductionist
- Mischel (1988) it can change depending on the situation we are in and who we are with.
(-) Explain how Eyesynck’s theory is biologically deterministic
- Suffers from same limitations as genetic and neural explanations.
- Eysenck only focused on the nervous system.
- Biologically deterministic.
