This study investigated sex role behaviors, perceptions, and aspiration levels in 3- 4-, and 5-year-old children. Focus was on social interaction in situations free of adult attention. Six parties were conducted and videotaped in the familiar setting of the preschool classroom. Seventy-seven preschoolers attended these parties which were composed of all girls, all boys, or a mixture of both sexes. Analysis of data did indicate that differential social behavior patterns were exhibited by various groups. Results are discussed in terms of implications for educational strategies. (DP)
