The Role of Neurobiological Deficits in Childhood Antisocial Behavior

ABSTRACT— Childhood-onset antisocial behavior is an important predictor of chronic and serious forms of antisocial behavior in later life. Both biological and social factors are involved in the development of abnormal behavior. We examine the underlying role of stress-response systems in the link between early social adversity and juvenile antisocial behavior, and propose that children with genetically and/or perinatally based neurobiological deficits have problems in activating these systems and therefore experience difficulties in regulating affect and behavior. Underactivity or attenuated reactivity of the stress-response systems may predispose antisocial individuals to seek out stimulation or take risks, and thereby explain deficits in learning and socialization. Further investigations of neurobiological functioning in antisocial children might not only indicate which children are more likely to persist in behaving antisocially but also guide the development of new interventions.
