The purpose of this study was to determine if the S-Programmed Articulation Control Kit could be effectively used with young adults with trading stamps administered for reinforcement. The study also investigated the possibility of selecting peers to aid in the carryover of the desired /s/ response to nonclinical situations.

Four college students displaying frontal lisps were selected as subjects for this study. The therapeutic sequence of the S-Programmed Articulation Control Kit was administered to all subjects. Trading stamps were administered for reinforcement following correct responses. Following the administration of the therapeutic sequence of the S-Programmed Articulation Control Kit, each subject then selected a close friend who was trained by the writer to discriminate between a correct and incorrect /s/ response. The peer then worked with the subject each day for two weeks tallying correct responses emitted by the subject. Both the peer and the subject were reinforced with trading stamps for correct responses produced by the subject's speech while the subject was unaware s/he was doing so. Correct and incorrect responses in these samples were calculated to determine if varryover was actually taking place.

Results of this study indicated that the S-Programmed Articulation Control Kit was effective in correcting frontal lisps of young adults. It was also determined that trading stamps were a positive reinforcer for young adults. Finally, it was determined peers could effectively be selected to aid in caryover procedures.
