psychological explanations Flashcards
the criminal personality
extraverts, neurotics, psychotic
extravert
underactive autonomous nervous system seek more arousal and therefore engage is risk-taking, dangerous, and maybe more criminal activities
- people high in extraversion are less easily conditioned and do not learn from their mistakes as easily or to avoid anti-social behaviour
neurotics
nervous, jumpy and over anxious. may be unpredictable and tend to overreact to situations of threath
psychotic
aggressive and lack empathy, they can be cold and unfeeling and are likely to engage in criminal behaviour
biology + environment
- personality has a biological basis, however it’s also affected by conditioning. extraverts find it difficult to learn how to behave appropriately and are less likely to learn from unpleasant consequences of behaviour
- criminals are unable to delay gratification
- criminals are more impatient, score highly on extraversion + neuroticism and are difficult to condition
evaluation - simplistic
eysneck
- too simplistic to consider personality in terms of just two dimensions (e&n)
- more modern theory called the five factor model (digman) suggests other personality dimensions such as openness to experience, agreeable and consciousness
- therefore reduces validity of eysenck’s explanation of personality as a cause of criminal behaviour
evaluation - self-report
eysneck
- personality tests lack validity because they depend on self-report data
- people tend to have social desirability bias so their answers may not be truthful. the epq consists of forced-choice items which must be answered yes or no
- this means the findings of the epq may lack validity and not reflect people’s responses in everyday life. this reduces the credibility of the research that supports and underpins eysenck’s theory of criminal personality
evaluation - sample/cultural bias
eysenck
- based on biased samples
- questioned in research by Bartol and Holanchock who studied hispanic and african groups in prison and divided them into 6 groups depending their criminal history and offence
they found that all groups were less extraverted than a non-criminal group, likely due to it being a very different cultural group
differential association theory
sutherland - offending behaviour can be explained by social learning. it’s about who you associate with
scientific basis
sutherland sought out a set of conditions that cause crime when present - 9 factors e.g association being with intimate groups, general ‘need’ for money is not a sufficient explanation for crime because not everyone with those needs turn to crime
crime as a learned behaviour
- individuals learn the values, attitudes, techniques for committing crimes and motives for criminal behaviour through interaction with significant others
- peers, family, and the local community may model criminal behaviour or may show accceptance of deviant attitudes (social norms)
- the learning experience (differential associations) vary in frequency and intensity for each individual
pro-criminal attitudes
if the number of pro-criminal attitudes the person comes to acquire outweights the number of anti-criminal attitudes, they will go on to offend
imitation of criminal acts
- the would-be offender may also learn particular techniques for committing crime
- also can learn by direct reinforcement (operant conditioning) if role models are seen as successful - this provides vicarious reinforcement
prisons
this theory explains why individuals imprisoned for a minor offence often reoffend when they are released. spending time with other criminals in the institution ( who may’ve committed more serious crimes) makes them likely to learn further criminal behaviour and attitudes
osborne and west - supporting evidence
differential association
40% of sons with a father with a criminal conviction committed a crime before 18, compared to 13% of sons of non-criminal fathers
farrington (2006) - supporting evidence
differential association
- longitudinal study of 411 males in south london area. findings described their criminal career up to age 50.
- 41% were convicted of at least one offence between age 10 and 50. most important risk factors from age 8-10 were criminality in the family, poverty, risk taking, poor parenting, poor school performance.
- 75% of offenders had offending parents
