A standard of performance, a valence statement, graphing of performance, and specific positive and negative informative feedback were used as a treatment package in a multiple baseline across subjects design to modify the self-help behaviors of institutionalized individuals. The effects of the treatment package for three of the four subjects were not considered important. Social contingencies were added to the treatment package in a reversal design in order to assess its effectiveness in the modification of the behaviors of the three subjects which were not noticeably affected by the original treatment package. The number of responses emitted after the addition of social contingencies of two the three subjects were not noticeably different from the performance on the original treatment package. The ineffectiveness of informative back led to the conclusion that it was not an effective reinforcer.
