Little prior research has examined children's interpersonal perceptions of peers from a social relations model framework. This study examines the degree of actor and partner variances, as well as generalised and dyadic reciprocities, in a sample of 351 sixth graders' peer nominations of different forms and functions of aggression and aspects of social status. Gender differences in these nominations are also explored. Results indicate significant actor and partner variances for all measures, and generalised reciprocity in social status perceptions. Clear gender differences were noted in rates of nominations, such that more same-sex than cross-sex nominations were generally given for both positive and negative aspects; however, we found mixed evidence of gender differences in the variance partitioning and reciprocity correlation estimates.
