A low resting heart rate is a good predictor of an indvidual who will seek excitement to raise their arousal level
Activity in the pre frontal lobes of the brain is shown to be lower in impulsive indivuals - in the adolecent brain the final connections to this area is still being formed
Birth complications and poor parenting combined with physical abuse and malnutrition, smoking and drinking during pregnancy all add to the risk |

| What were the results of Brunner's study? |
|

the tests showed disturbed monoamine metabolism associated with a deficit of the enzyme MAOA - a point mutation was indentified in the x chromosone of the gene responsible for the production of MAOA
MAOA is involved in serotonin metabolism likely to be responsible for their mental retardation and violent behaviour |

absenteeism from school also correlated negatively with homicide rates
contributing factor is inequity or the unequal distribution of wealth and resources in society |
