This study quantifies genetic and environmental contributions to these two forms of aggression in an ethnically diverse urban sample of 9-10 year old twins (N = 1219), and compa...
متن کاملThe Differences in Normative Beliefs among Schoolchildren with Reactive, Proactive, Reactive-Proactive Aggression, and without Aggression
