- Neural explanations for offending behaviour
- Biochemistry
- High levels of noradrenaline are linked to violence and aggression
- Serotonin controls mood and impulse
- Low levels could cause impulsive crimes
- Dopamine is linked with addiction and substance abuse
- Dopaminergic activity in limbic system = pleasure is experienced through activity
- Higley et al (1996) Positive correlation of testosterone and aggression but not impulsivity in male primate
- Comparative psychology (differences in norms, morals and cognition)
- Brain physiology
- Limbic system controls emotions
- Criminals lack remorse and guilt
- Raine suggested frontal lobe is smaller in antisocials than others
- Lack guilt and moral conscience
- Raine (1997) Compared brains of murderers and non-criminals Abnormal activity in limbic system and thalamus
- Limbic system controls emotions
- Biochemistry evaluation
- Reductionist
- Only one neuro-transmitter as cause is too simplistic
- Allows us to focus on a specific chemical cause; allows treatment
- Biologically deterministic
- Reductionist
- Brain physiology evaluation
- Empirical methods iimprove reliability, validity and objectivity
- Small sample sizes in research = harder to generalise
- Only applicable for murder cases due to murderous sample
- Biochemistry
