Developmental Origins of Aggression

Show Summary Details


This chapter explains that in the course of executing the Montreal Longitudinal-Experimental Study, the author became convinced that some of the developmental origins of antisocial behavior were situated in the period prior to kindergarten. This chapter especially focuses on toddler’s aggression, anger, oppositional behavior, defiance, and overt disregard for rules. The author states that he is much aware of environmental factors that impinge on the development of antisocial behaviors, including intergenerational transmission of the behaviors. The chapter stresses the importance of gene expression studies (epigenetic) that indicate that environmental risk factors related to the mother “may start to have their impact on the child’s developing brain and eventual self-control problems during fetal life, and soon after, through their impact on gene expression”.
