Children spend much of their time in the company of their peers, and they do so within cultural contexts that play a signifi cant role in their peer relationships (Rubin, Bukowski, and Parker, 2006). For example, cultural beliefs and norms help interpret the acceptability of individual characteristics and the types and ranges of interactions and relationships that are likely or permissible (Rubin et al., 2006). Yet, the vast majority of studies pertaining to children’s peer relationships have focused primarily on Western European and North American samples. Today, researchers examine peer relationships from a cultural perspective; emerging data suggest that there is considerable cultural variability in children’s peer experiences (Chen, French, and Schneider, 2006). us, in this chapter, we review the extant cultural and cross-cultural psychological literature on children’s peer interactions, relationships, and groups.
