abstract="The results of this study support the idea that participation in sociodramatic play builds the language competence of young children and give added credence to the position that play is a vital part of good preschool programs. Specifically, the study tested the hypothesis that 3- and 4-year-old children from a variety of backgrounds who were enrolled in a preschool program with planned Sociodramatic play opportunities and play tutoring would demonstrate greater than expected language development. Results showed that boys demonstrated significantly greater than expected growth on the Peabody Picture Vocabulary Test (PPVT) after 3 months of participation in enriched Sociodramatic play with play tutoring.<p />",
