Most sociometric research is based on same-age, mixed-gender classroom groups. By contrast, this study examined eight ad hoc play groups of mixed ages (6 and 7 years) and same gender at three levels of social organization: individual status, mutual dyads, and mutual triads. A total of 96 children in groups of 12 nominated three most- and least-liked peers before and after 10 consecutive weeks of after school free-play sessions. Significant age differences occurred in the Age X Gender X Time ANOVAs: at the individual status level, older children were more socially visible. At the mutual levels, older children had more friends and enemies and more triadic relations. No age differences occurred for social preference, or for the categories of popular, rejected, neglected, controversial, or average status. Age also played a significant role in the composition of dyads and triads: 87 percent or more of mutual liking dyads and 100 percent of triads were between same-age children. The 10-week stabilities of status were quite similar to those reported for classrooms. Preference was more stable than visibility. Rejected status was the most stable and neglected status the least. Mutual liking dyads were more stable (54 percent) than disliking dyads (30 percent). Triads were rare and unstable. Gender had no appreciable impact on social relations. (Author/RH)
