Both modeling and feedback procedures have been found to be effective in the modification of a wide variety of behaviors. Comparisons of these procedures applied either singly or in combination have been few and the results of these studies have been inconsistent. This investigation compared the relative efficacy of modeling and feedback procedures applied singly and in combination. Specifically, a modeling on video tape procedure and an instruction plus feedback procedure were compared. A combination procedure consisting of both modeling on video tape and instructions plus feedback was also compared to the procedures used separately. Comparisons were made of the effectiveness of these conditions in increasing the appropriate peer interaction of three retarded adults. Social interactions consisted of verbal, recreational, and cooperative responses. A counterbalanced, multiple baseline, experimental design was utilized. This design enabled treatment comparisons to be made within each subject's performance on the three responses. The design also allowed for comparisons of collateral changes accompanying training on each of the three responses
