Preschoolers Use Trait-Relevant Information to Evaluate the Appropriateness of an Aggressive Response.

The tendency for 3- to 5-year-old children to use trait-relevant information about other people when evaluating aggressive responses to ambiguous behavior was examined across two studies (N = 81). Children were more likely to endorse the use of aggression against a "mean" versus a "nice" story character. Additionally, they were more likely to endorse the use of aggression against a story character who feels happy rather than sad when bad things happen to other kids. These findings suggest that, as early as preschool, trait-relevant information about other people can serve as a tool with which children evaluate the appropriateness of aggression in response to ambiguous behavior. Moreover, these findings provide evidence that even before the onset of formal schooling, trait and mental state information can influence social judgments.
