The result of this study divided into there parts. Before the scripts of sociodramatic play created by young children themselves, they selected and adopted fairy tales to be their scripts of sociodramatic play. In this process, the most important of young children's negotiation behavior was the "roles", which was one of the essential factors of sociodramatic play. Young children took several methods to negotiate the problems of sociodramatic play, such as metacommunication, interpretation and explanation.
