The purpose of this study was to investigate the relationships between mothers involvement of their childrens peer interaction, their memory of childhood peer relations, and their perception of childrens social competence. Subject consisted of 302 mothers of 4- to 6-year-old children. A sample of mothers completed a series of questionnaires assessing their peer experiences, perceptions about their childrens sociability, and a behavioral checklist of their involvement activities. The results indicated that mothers own sociability and their perceptions of their childrens sociability influenced their involvement. More intense maternal involvement occurred when mothers perceived their children to be sociable. Mothers with sociable peer recollections appeared to take more active role in their childrens social development.
