What did Eysenck say caused a criminal personality?
Inheriting a type of nervous system that affects their ability to learn and adapt to the environment
How does Eysenck say Extraversion is caused?
By inheriting an under-aroused nervous system and so seek stimulation to restore the optimum level of stimulation
How does Eysenck say Neuroticism is caused?
By inheriting a nervous system that is unstable in stressful situations, so prone to overreacting to stimuli and being quick to anger or fear
How does Eysenck say Psychoticism is caused?
Psychoticism has been related to high levels of testosterone.
How does Psychoticism lead to criminal behaviour?
Lack of self-control leads to more impulsive crimes e.g. violent crimes
How does Extraversion lead to criminal behaviour?
More arousal/stimulation needed, so seek out dangerous situations, more impulsive actions e.g. theft, robbery
How does Neuroticism lead to criminal behaviour?
More reactive to stressful situations, therefore more likely to commit violent crimes as they may be quick to anger e.g. murder, assault
What did Eysenck believe that criminal behaviour could be explained through?
A combination of innate personality traits and socialisation. Someone can be born with traits that predispose them to criminality, but the interaction with the environment is important in the development of criminal behaviour
How does Eysenck’s role of socialisation theory link to conditioning?
The socialisation element occurs during childhood where children are taught that bad behaviour will be punished (operant conditioning).
What types of people are less easily fear conditioned? What does this mean for their development?
What is one issue with the research to support Eysenck’s criminal personality theory?
It was conducted by the psychologist that came up with the theory so therefore the findings may be biased
What are 2 strengths to evaluate Eysenck’s criminal personality theory with?
What research supports Eysenck’s criminal personality theory?
Eysenck and Eysenck (1977)
2070 male prisoners and 2442 male controls were given Eysenck’s personality questionnaire. They found that prisoners scored higher than controls in all three scales
How does Eysenck’s criminal personality theory consider nature and nurture together (interactionist)?
Someone may have been born with an under aroused nervous system, which leads to extraversion, however they may not be socialised in a way that means the under-aroused nervous system becomes a problem
What is one weakness to evaluate Eysenck’s criminal personality theory with?
Why does Eysenck’s personality theory have an issue with measuring personality? What did Eysenck do to counter this?
Since Eysenck’s personality questionnaire is a self-report measure, SDB may be in effect as they may answer in a way to appear a better person. Eysenck included lie scales to see when someone is inputting false data, so he discarded these data points
What is the second individual differences explanation of criminal behaviour?
Cognitive factors
Which stage of moral reasoning are most criminals in? Why?
Preconventional - crime is acceptable as long as they aren’t caught. Crime is done for personal gain.
How is crime justified at each level of moral reasoning?
Pre - Justifiable if the punishment can be avoided or the rewards outweigh the cost
Conventional - Justifiable if it helps maintain relationships or society
Post - Justifiable if it helps maintain human rights or further social justice
