title: Effect of contingent and non-contingent social reinforcement on the cooperative play of a preschool child.
abstract: The effect of adult social reinforcement on the cooperative play of a five-year old girl in a preschool setting was assessed under two conditions: (1) presented randomly throughout the school day, and (2) presented contingent on cooperative play. Only in the latter condition was a significant change in cooperative play observed.
