Raine et al study Flashcards
1
Q
What were the 2 hypothesis
A
- Dysfunction in brain structures prefrontal cortex, corpus callosum, left angular gyrus and limbic system will be found more often in murderers than a control group of non murderers
- Dysfunction in brain structures prefrontal cortex, corpus callosum, left angular gyrus and limbic system will be found more often in murderers, than dysfunction in other areas of the brain that have been implicated in non violent psychiatric disorders
2
Q
Points for methodology
A
- Quasi
- IV
- DV (operationalised)
- Participants (numbers and age and gender)
- Reasons for NGRI for murders
- what happened 2 weeks before
- controls (screening)
3
Q
What were reasons for NGRI
A
Schizophrenia - 6 Affective disorder - 2 Personality disorder - 2 learning disability - 3 Head injury - 23 drug abuse - 3 epilepsy - 2
4
Q
Points for procedure
A
- how were pps selected
- injection (location of brain metabolism FDG)
- Time for FDG to be taken up
- PET scan (when, what how)
5
Q
Points for findings
A
- Prefrontal cortex (self control)
- Parietal (education)
- temporal (non)
- Corpus callosum (right inhibits left)
- Amygdala
- Thalamus (higher in right)
- Areas previously linked to violence (lower)
6
Q
Points for conclusions
A
- amygdala, medial temporal, thalamus (more violent behaviour, fearlessness, can’t learn negative effects of violence
- Differences in brains of NGRI vs average person
- Doesn’t suggest violence is bio determined
- ## doesn’t excuse their behaviour
