The importance of the peer's gender Gender also matters in children's choice of play companions (Martin et al., 2013; Mehta & Strough, 2009). Up to age 3 or 4, children are equally likely to choose same-gender or other-gender companions for play. Up to age 7, they are willing to play with a peer of the opposite gender. But over the course of elementary school, both boys and girls increasingly choose playmates of the same gender and exclude children of the other gender (Furman & Rose, 2015; Rubin et al., 2015). This preference for same gender play partners is evident across a range of non-Western cultures (Monroe & Romney, 2006). The genderexclusivity rule has exceptions, of course, but they often operate underground. For example, a girl and boy might spend time together at church or in the neighborhood, but they keep their friendship a secret from their classmates (Gottman, 1986; Thorne, 1986). They don't want to be teased or taunted at school. This trend holds until at least adolescence. Even then, the prevalence of friendship groups that included both girls and boys rose only from 10 percent to 22 percent from the sixth to ninth grade (Molloy, Gest, Feinberg, & Osgood, 2014). Gender segregation is obvious at school as boys and girls play different games and use different equipment (Blatchford et al., 2003; Leaper, 1994, p. 29): Need Assignment Help?
