Aim: To make a multifactorial approach to understanding antisocial behaviour in children.
- PET Scans.
- A meta-analysis of a selection of articles.
- Covering neuropsychological, neurological and brain-imaging studies as they relate to anti-social behaviour in children.
- A low resting heart rate is a good predictor of an individual who will seek excitement to raise their arousal level, creating a fearless disposition.
- The adolescent brain is still forming its final connections in the pre-frontal lobe right up until the early twenties.
- Activity in the pre-frontal lobes of impulsive individuals, who are more likely to be antisocial and aggressive, is lower.
- Birth complications and poor parenting with physical abuse and malnutrition, smoking and drinking during pregnancy all add to the risk.
Conclusions: Raine concludes that early involvement and prevention may be an effective method of reversing biological deficits that predispose to antisocial and aggressive behaviour.
