This study examined young viewers’ evaluations of the social and physical aggression that is endemic in tween sitcoms. Preadolescents (N = 176) were randomly assigned to watch a tween sitcom that featured a protagonist or antagonist committing social or physical aggression (two exemplars at each level). As suggested by recent work on disposition theory and moral development, participants’ moral evaluations of the depicted aggression were related to their liking of the perpetrator, not their perceptions of the severity of the aggression. Furthermore, there was support for the causal chain proposed by Raney’s formulation of disposition theory, whereby protagonist liking predicted moral indifference, which further predicted self-reported likelihood of imitating the aggression. This path was stronger at higher ratings of funniness. When aggressors were perceived as likable and their actions as funny, viewers reported more indifference and greater likelihood of imitation.
