As individuals mature they may engage in less direct aggression and more indirect aggression, a form of heterotypic continuity, because the risk of punishment for indirect aggression is far less (Bjorkqvist, 1994) which is in line with the present findings showing higher scores on most of the direct aggression measures for early adolescents.
