Abstract
Through use of an ABAB design and momentary time‐sampling procedure, 10 elderly members of an adult day care center were observed for their social responses during two separate baseline (A) and intervention (B) conditions. Intervention consisted of an intergenerational nursery school. Baseline data were obtained before the program started and when school was not in session. Repeated‐measure ANOVA indicates that the elderly participants showed significantly higher levels of social interaction and significantly lower levels of solitary productive behaviors when the preschool program was in session than when it was not.
