peers generally increases risk for aggression among kindergarten aged children, it can be particularly detrimental for those who are also genetically predisposed (van Lier et al., 2007). Together, these studies suggest that minimizing exposure to peer antisocial behavior may serve to protect adolescents with heightened genetic risk, decreasing their subsequent likelihood of engaging in problematic externalizing behavior. However, to our knowledge, no study has yet demonstrated this effect with respect to the risk associated with a specific gene.
