Interaction effects of social and tangible reinforcement

Interaction effects between tangible and social reinforcement with children were investigated by comparing bar press rates of three groups of kindergarten children under three different reinforcement conditions: tangible, social, and tangible alternated with social reinforcement. Following the reinforcement period bar press rates of the three groups were compared during a brief period of nonreinforcement. In addition, the effects of sex and density of reinforcement were investigated.
