- Raine
- Claims
- Damage to prefrontal cortex may cause people to have altered behaviour.
- Damage to prefrontal cortex= more aggressive or violent.
- Components
- Raine used a PET scanner of 41 impulsive killers who had pleaded reasons for insantiy as their defence.
- Damage to prefrontal cortex was found in ALL killers.
- Murderers pleading insanity had big differences in brain function compared to non-murderers.
- PET scan shows blood flow in brain and the size of brain areas.
- Credibility
- Highly scientific and objective.
- The research can be repeated easily.
- Generalisations can be made if the sample size is large enough.
- Doesn't say when damage to PFC happened, could've been after crime.
- Correlation does not prove causation.
- Reductionist- imples that PFC damage leads to violent offending.
- Deterministic- doesn't consider environmental factors.
- Analysis
- Michael- 40 year old married man and had a step-daughter.
- Suddenly, in 2000 he used *********** and molested his step-daughter.
- Night before sentence he complained of a headache.
- He completed a therapy programme and soon went home.
- He was normal when he came back.
- The headaches came back and he began to develop an interest in it again.
- He had a tumour growing at the front of his brain.
- Refuting Evidence
- It can only be generalised to murderer's pleading not guilty due to reasons of insanity.
- No non-violent criminals means the study isn't representative and can't be compared to all crime.
- It only describes the differences in the prefrontal cortex, rather than explaining them.
- Raine stated that the PET images weren't clear and a limit on how accurate they were.
- So, study lacks internal validity.
- Supporting Evidence
- Bufkin and Luttrell
- Used results of 17 studies that use brain imaging to study aggression in humans.
- They found that all studies point to similar conclusions.
- Bandura
- Claimed if people learn aggressive behaviours, their brains might change because of it.
- So, physical aggression may be hard wired into the brain after it's learnt through childhood.
- This support Raine because Bandura stated changes in the brain lead to violent behaviour.
- Bufkin and Luttrell
