Aim: To support the theory that an abnormal prefrontal cortex causes APD
Method: MRI ( Magnetic resonance imaging) was used to test 21 men with APD and a control group of 34 healthy males. ps all volunteers
Results: The APD group had an 115 reduction in prefrontal grey tissue compared with the control group
Conclusion: APD is caused by a reduced prefrontal cortex
Indpendant: The groups of men had different number and 1 group at APD and the other was healthy
Dependant: The amount of grey tissue in the prefrontal cortex
Evaluation: + It adds support to the idea that there are bioloical explanations for APD. A brain abnormality in the prefrontal cortex
- Only male- Andocentric bias
- Volunteer p.s Not a representative sample to generalise from
