Psychological Explanations of Offending Behaviour Flashcards
What did Eysneck explain?
Eysenck (1982) explained criminal behaviour in terms of 3 biologically determined (innate)
personality traits.
Extraversion, neuroticscm, psychoticism
What is Extraversion?
- The overall level of arousal in a person’s nervous system.
- Extraverts are under aroused and seek external stimulation to increase their cortical (brain)
arousal and then engage in dangerous activities.
What is neuroticism?
- The level of instability in the sympathetic nervous system. A neurotic person is someone who is slightly unstable and reacts/gets easily upset quickly.
- They are therefore prone to over-react to situations of threat, which would explain some
criminal activity
What is Psychoticism?
- A psychotic person is overly aggressive and lacks the ability to empathise with others’ feelings.
-These behaviours are easily linked to criminality.
A03 - Research - Research: Mischel and Peake (1982)
- One issue of this theory is the underlying assumption that personality is consistent.
- A number of psychologists suggest that people’s behaviour may vary systematically
across situations. For example, someone may be relaxed and calm at home but quite
neurotic at work.
-Mischel and Peake (1982) asked family, friends and strangers to rate 63 students in a variety of situations and found almost no correlation between traits displayed.
-Apparent regularity of behaviour is likely to be due to the fact we often tend to be in
similar situations.
-Therefore, the notion of a criminal personality is flawed as people don’t simply have a
single fixed personality.
A03 - Social Influence
- Eysenck suggests that the three personality traits are caused by abnormal activity in the
nervous system. - However, personality traits can be learnt from peer groups, family members, or norms in
a sub-culture (e.g. neighbourhood). - These social influences could have a more significant effect upon behaviour than innate differences in brain structure.
-Therefore, it is likely that much crime is due to factors that are ignored in this biological
explanation.
A03 - Biologically Deterministic
One weakness of Eysenck’s explanation for offending is that it may be seen to be
biologically deterministic.
-The criminal justice system assumes that individuals have free will and so punish
crimes on this basis.
- If Eysenck’s theory was assumed to be correct it would suggest that criminals are not
truly responsible for their behaviour and therefore should not be punished.
-This is important because it contradicts the legal system within which crime is
prosecuted.
