“…Although same-sex groups are clearly a strong feature of early and middle childhood, children at the same time also participate in cross-sex interactions and relationships (Archer, 1992). There is evidence that cross-sex encounters and relationships in themselves can be viewed as a separate social world (Benenson, Del Bianco, Philippoussis, & Apostoleris, 1997;Bukowski, 1990;Bukowski, Gauze, Hoza, & Newcomb, 1993;Dolgin & Kim, 1994;Hops et al, 1997;Leaper, 1991). Accordingly, it is possible to conceive children's cross-sex relationships as occurring in parallel with same-sex relationships, with children to some degree learning separate patterns of interaction in same-sex and cross-sex relationships, rather than learning strategies from same-sex relationships that are transferred to cross-sex relationships.…”
