Theories that decouple peers from other societal influences confront the major task of explaining where the peer's views supporting gender differentiation come from. Gender constancy and gender labeling have been tested as explanatory factors but they have proven no more successful as predictors of peer segregation conduct than of individual gender conduct (Fagot, et al., 1986; Moller & Serbin, 1996; Smetana & Letourneau, 1984; Yee & Brown, 1994). Another explanatory possibility was that boys and girls are, for some reason, attracted to different types of toys and activities. Differential attraction presumably fosters gender segregation that shapes differential gender conduct. This view begs the question of the source of the attraction. If it is innate there is much discordant evidence in the variability and changeability of gender conduct that needs explaining. If the attraction is socially instilled, as the previous empirical analyses suggest, then the peer group is not the initiating agency of gender differentiation but rather the reflection of the normative orientation of the society at large.
