Brain activity in murderers compared to non-murderers, to see if murder is due to nature or nurture
Brain activity in criminals, to see if breaking the law is due to nature or nurture
8. Murderers have abnormal activity associated with...
Lack of personal relationships
Lack of fear, lowered self-control and low IQ
Lowered happiness, and loneliness
9. In the lateral and medial pre-frontal cortex, murderers showed much less...
Glucose metabolism

Activity
10. What are the weaknesses of using a matched pairs design?
Participant variables occur
Individual differences were ignored and something vital to the real cause of murdering may not be measured
Demand characteristics and order effects occur
11. In a 20 year longitudinal study, Raine measured how 3 year olds learned fear. He found some showed little or no fear responses, despite being exposed to unpleasant noises. What did he find in these children 20 years later?
Were less likely to have friends
Were more likely to have a criminal record
Were more likely to be afraid of unpleasant noises
12. Before going into the scanner, what were participants asked to do?
Nothing
Begin the continous performance task - Required brain programming
Begin the individuality task
Begin the interference task - Required brain programming
13. Why were participants injected with a commonly used radioactive glucose tracer (FDG)?
To increase brain activity in the temporal lobes of murderers
To increase brain activity in the frontal lobes of normal participants
To increase brain activity in the temporal lobes of normal participants
To increase brain activity in the frontal lobes of murderers
14. What type of scanner were the participants transferred to?
fMRI scan
PET scan
CAT scan
15. How can this study be applicable?
Lawyers can overthrow death sentences if there is evidence of brain abnormalities
