An attempt was made to modify a socially desirable response of mental patients. It was found that instructions to the patients had no enduring effect unless accompanied by reinforcement. Also, it was found that reinforcement was not effective unless the reinforcement procedure was accompanied by instructions that specified the basis for the reinforcement. Maximum change in behavior was obtained when the reinforcement procedure took advantage of the existing verbal repertoire of the patients. A significant methodological finding was that substantial modification of the behavior of psychotics could be achieved by briefly delaying, rather than withholding, food reinforcement.
