The information contained in this report is intended for the "Sesame Street" writers who are assigned the task of creating program material in the interpersonal area. This information will also be useful for evaluation of program materials aimed at interpersonal goals. First, a list of interpersonal strategies is presented; these are: cooperation, conflict resolution; and differing perspectives. Each strategy describes a class of activity that is common to the interpersonal behavior of young children. In Part II of this report, each strategy is presented in relation to its descriptive definition and its interpersonal function. In Part III, detailed information on each strategy is given. In addition, some details about the circumstances in which each strategy is likely to occur and the frequency with which the strategies were observed in the behavior of young children are indicated. The strategies, their descriptive definition, and the examples given are based on actual classroom observation. An appendix provides descriptions of classrooms visited during the study. (Author/DB)
