Biological Factors and Violence

Biological factors refer to a wide array of neurological, physiological, or chemical in¢uences on aggression and violence. As Bartol and Bartol (2007) noted, recent advances in the neurosciences have revealed that biological factors, interacting with the social environment, may have some signicant in¢uences on child development. –e exact nature of these in¢uences remains largely unknown.
