Toddlers' expectations of corporal third-party punishments against the non-defender puppet

Abstract

Recent research has demonstrated that toddlers expect individuals to approach and reward those who defend a victim from an aggressor rather than those who refuse to do so. This work focused on toddlers’ expectations of corporal third-party punishments trought various actions, such as hitting with a stick or repelling someone who refused to defend a social partner following aggression. Using a violation of expectation paradigm (VoE), three experiments were carried out to investigate whether 21-month-olds expect others to apply different kinds of corporal punishments against the non-defender puppet (expected event) rather than the defender puppet (unexpected event), showing a bystander hitting with a stick (Experiment 1) or pushing strongly (Experiment 3) each of the two puppets. In both experiments, toddlers showed to be surprised whent the saw the bystander punish by hitting or pushing the defender puppet rather the non-defender puppet. In a control experiment displaying a non-social condition (Experiment 2), in which the victim puppets were replaced by two inert boxes, toddlers showed no expectation. These results uncovered that toddlers expect others to engage in different corporal punishments toward those who refuse to defend a social partner from an aggressor, by revealing that these expectations are not specific to a single type of punishment. The findings raise questions about the development of corporal third-party punishments, and have implications for the theory on ontogenetic processes underlying sociomoral development.
