CB individual difference explanations Flashcards
what is the first ID explanation of criminal behaviour
Eysenck’s criminal personality
what is meant by personality
it is the individual mix of traits and characteristics which makes us individual and sets us apart from other people. although the specific traits are not unique to use, the balance of them is. personality is relatively static and doesn’t change significantly over the course of one’s lifetime, can be influenced by the environment
what is Eysencks theory of personality based upon
the idea that character traits tend to cluster along three dimensions
what are the 3 dimensions
extraversion
neuroticism
psychoticism
7
what is extraversion
a trait that describes differences between people in their social interactions, positive emotions, impulsivity and energy levels. highly extraverted people are generally outgoing, energetic enthusiastic and positive
opposite=intraversion
what is neuroticism
a long-term tendency to be in a negative or anxious emotional state. people with neuroticism tend to have more depressed moods and suffer from feelings of guilt, envy, anger and anxiety more frequently and severely than others.
opposite=stability
what is psychoticism
characterised by aggression, impulsivity, aloofness and antisocial behaviour, indicating a susceptibility to psychosis and psychopathic disorders (antisocial personality disorder)
opposite=normality
what did Eysenck suggest about each personality trait
each has a biological basis which is normally innate, claiming 67% of the variance for the traits is due to genetic factors
biological basis of extraversion
driven by natural levels of arousal in a person’s nervous system. extroverts are inherently under aroused and so seek external simulations to stimulate their cortical pathways
biological basis of neuroticism
driven by the level of stability in the sympathetic nervous sytem and the way they respond to situations of threat (fight or flight) a neurotic person is considered unstable and reacts ‘quick to threats’
biological basis of psychoticidm
driven by higher levels of testosterone
as men have more of this hormone than women, they tend to score higher in this dimension
link of extraversion to criminality
seek more arousal so enterninto more dangerous activity (CB)
more sociable, more opportunity to commit crimes e.g. out late so don’t think they’ll get caught
link of neuroticism to CB
they’re unstable and irritable and are therefore prone to over-react to situations of threat, could explain some criminal activity (may perceive a situation as being threatening when it isn’t)
enter into sensation seeking behaviour by a way of self medicating/raising low mood =drugs
links of psychoticism to CB
typically aggressive individuals so more likely to enter into behaviours with the intent of harming others. narcissistic so driven by their own wants and needs (lacking empathy for others so don’t care for their feelings)
what causes certain personality traits to lead to criminal behaviour
an individual is born with certain personality traits but interaction with the environment is essential in the onset of criminality
what did Eysenck say about those high in extraversion and neuroticism
less easily conditioned and therefore they do not learn to avoid anti-social behaviour
strength of Eysencks theory of criminality
ID 1
there’s additional support for a link between one’s personality and criminal behaviour. research has compared the personalities of criminals and non-criminals. Dunlop et al. found that both extraversion and psychoticism were good predictors of delinquency
PB point for Dunlop’s research
ID explanation 1 for CB
delinquency was an assessment of minor offences in the previous 12 months (e.g. theft was included) another study by Coleta van Dam et al. found that only a small group of male offenders in a juvenile detention centre had high scores on all three of Eysenck’s variables.
what does Coleta van Dam et al. research suggest
(strength ID explanation 1 for CB)
there is conflicting evidence and so confusion as to the extent to which personality and criminal behaviour can be linked with one another
another strength of ID explanation 1 for CB
further supportive evidence.
Zuckerman found via twin studies a +0.52 correlation in identical twins for neuroticism compared with a +0.24 for non-identical, suggesting a large genetic component. for extraversion the correlation coefficients were +0.51 for MZ twins and +0.12 for DZ twins. Zuckerman provided similar data for psychoticism
PB point for zuckerman’s research
strength 2 ID explanation 1 for CB
even though such figures imply a strong genetic component to the personality traits identified as important for criminality by Eysenck it is not as strong as expected, a +0.50 correlation means that about 40% of the variance in these traits is due to genes. it could also be possible that the higher figure seen in MZ twinds could be due to the shared environment between the set of identical twins.
suggesting : a lack of 100% concordance rate between identical twins implies that other factors are at least as important in determining personality as one’s biology
weakness of ID explanation 1 for CB (eysenck personality
any theory based on personality has to adopt the stance that personality is fixed. Although a number of psychologist support a situational perspective, suggesting that people may be consistent in similar situations, but not across situations. for example, someone may consistently relax and calm at home but neurotic in a work setting.
