Some biological predispositions and multivariate analysis of the bio-psycho-social correlates of violent prisoners

Impulsiveness and violence are types of behaviour that may be linked to criminality, whereas aggression is recognized as a fundamental human drive or instinct. A discharge of destructive energy transforms aggression into violence. The aetiology of violence is related to all levels of human functioning and may be traced to biology, personality and social norms. We assume a rather strict determinism of human behaviour, which ranges within a configuration of somatic and environmental factors. We envisage three levels of interaction involved in the genesis of human behaviour: biological, psycho-personal and socio-cultural imprints.
