Influences of gender identity on children's maltreatment of gender-nonconforming peers: a person × target analysis of aggression.

We investigated whether gender identity influences preadolescents' tendency to single out gender-atypical peers for abuse. Data were gathered from 195 boys and girls (M age = 10.1 years) in the fall and spring of a school year. Children self-reported multiple dimensions of gender identity (intergroup bias, felt pressure for gender differentiation, felt gender typicality, gender contentedness); peers assessed each other's social behavior (gender nonconformity, aggression toward each classmate). Using multilevel modeling, we examined how children's attacks on gender-nonconforming peers (relative to their attacks on other peers) changed over the school year depending on their gender identity. There was modest support for the hypothesis that overconfident, arrogant gender identity promotes abuse of gender-atypical peers but considerable support for the hypothesis that insecure, self-questioning gender identity fosters this tendency. Implications for issues central to contemporary personality theory (e.g., Person x Situation interaction) are discussed. New and somewhat surprising information about the cognitive and behavioral characteristics of gender-nonconforming preadolescents is provided.
