Four papers address issues related to behavioral training approaches to help mentally retarded persons secure competitive employment. In the first, a combination of role-playing, modeling, and response feedback was systematically applied to accelerate appropriate responses of a 33-year old moderately retarded male to criticism, humor, and assistance seeking. In the second paper, a simulation training program was used to teach bank depositing skills to a moderately retarded (Down's Syndrome) adult. In the third paper, a reinforcement point system was used to increase appropriate job completion of a mentally retarded young adult in a natural community job setting. The final study describes how self-recording dramatically reduced the frequency and duration of early check-outs from work by a severely disabled mildly retarded adult worker. (CL)]
