Amygdala and APD: Raine et al (2000)

Aim – To support the theory that abnormalities in the prefrontal cortex cause APD.
Method – Magnetic resonance imaging (MRI) was used to study 21 men with APD and a control of 34 healthy men. The subjects were volunteers.
Results – The APD group had 11% reduction in prefrontal grey matter compared with the control group.
Conclusion – APD is caused by a reduction in grey matter.
The study supports the biological explanation of APD.
1. POSITIVE EVALUATION:
Raine and colleagues only studies males so can’t relate the findings to women.
1. NEGATIVE EVALUATIONS:
Participants were volunteers so not representative of all people.
Behaviours linked to one area of the brain often results from a deficit elsewhere in the brain. The cause of APD could be more complex than the study suggest.
