In a seminal study for the social cognitive theory, Bandura (1965) drew a distinction between acquisition and performance. Children viewed a violent film. After viewing the program, some children, particularly boys, spontaneously incorporated those aggressive actions in their play. Other children, primarily girls, did not spontaneously imitate the observed aggression. However, when offered incentives to do so, most children were quite capable of depicting the aggression they had viewed which indicated that the actions had been learned even if not performed. This finding suggests that girls may think about the aggressive actions that they view, even if they do not necessarily act aggressively.
