Palmer & Hollin
97 convicted males (arson,assult,burglary) compared to 77 non-offenders
Given short scenarios and asked why the protagnoist acted the way they did:
E.g sitting home watching TV alone. Knock at the door policeman wants to talk. Why are they there?
To be nice? To be mean? Not sure?
Found juvinile delinquents more likely to rate an amigious situation as hostile compare to a non-offender.

Maoa- enzymes responsible for breaking down dopamine & seretonin
Genetic predisposition possible influence for behaviour
Brunner
Family in Netherlands.
5 males, violent (arson, ****)
Urine samples
Defect in maoa enzyme carried on x chromosome.
affected ability to break down seretonin and dopamine had low levels of seretonin and high levels of dopamine which could be the cause of criminal behaviour.
Biology- Brain Dysfunction

Phineas Gage- pole through frontal lobe, brain damage. Altered personality - rude & aggressive.

41 murder pleading insanity-reasons: head trauma, schizophrenia, non murder control group.
PET scans
Less activity in criminals pre-frontal cortex- linked to loss of self control, social inhibitor, tells you whats right/wrong
Corpus Callosum- lower activity in criminals, may stop L brain inhibiting R brains violence.
Biology- Gender
Girls traditionally socialised to be more conforming and strictly supervised by parents.
Males more likely to take part in risky behaviour eg. drugs, fights - evolutionary perspective to survive and impress females.
