etiology of anti social behaviour
Society must accept responsibility to control anti-social behaviour among adolescents, in order to limit youth violence. Four theories of child anti-social behaviour are neoclassical, biological, psychological, and the economic/ sociological theory (Hoge & Andrews, 1996). ... Research provides support that biological and environmentally based anti-social behaviour may be overcome through social and educational programs aimed at high risk individuals, leaving deterrents and medical treatments as a last resort. ... Longitudinal studies show males born with a sluggish version of the gene for monoamine oxidase A, or MAOA, tended to have a higher level of aggression and anti-social behaviour. ... Although the only 12 % of the abused boys possessed the low-activity MAOA gene, 85%of these boys developed anti-social behaviour. ... Twin and adoption studies support the evidence that MAOA deficiency in human males is associated with increased impulsive aggression as well as other types of abnormal behaviour (Brunner, 1996).
