Self–other awareness and peer relationships in toddlers: gender comparisons

Toddlers' growing self–other awareness has been linked with their ability to interact with peers, but there is reason to think that self–other awareness may relate to different aspects of peer relationships for boys and girls. We hypothesized that boys would express self–other awareness by separating self from other through claiming toys, while girls would express self–other awareness by creating similarities between self and other through use of the duplicate of a partner's toy. For 52 22–26 month olds, self–other awareness was assessed through four tasks: mirror self recognition, perceptual role taking, pronoun recognition and pronoun use. Each child subsequently interacted with a same‐sex peer for 30 min. Girls high in self–other awareness, and their partners were more likely to engage in duplicate toy use than girls low in self–other awareness. No differences in toy claiming were found. Future longitudinal research would clarify how the onset of self–other awareness relates to developments in peer interaction for girls and boys.
