A recruitment-of-praise package to increase productivity levels of developmentally handicapped workers.

This research examined the effectiveness of a recruitment package to increase production rates of three developmentally handicapped adults in a sheltered workshop. A baseline phase measured production rates of a paper-folding task under "typical" supervisory conditions. The recruitment package, introduced in a multiple-baseline design across subjects, involved goal setting by the experimenter, and self-monitoring, recruitment of praise, and self-delivery of a "happy face" by the worker. The recruitment package increased the production rates for two subjects, but decreased production rates for the third subject. Social validity data indicated that all subjects preferred the recruitment package, and staff continued to employ the recruitment package for two subjects when the formal research was terminated.

Self-management with picture prompts to improve quality of household cleaning by severely mentally handicapped persons.

A strategy was devised for measuring quality of household cleaning by four severely mentally handicapped adults living in a community residence. Two interventions were then compared for improving quality of cleaning. One intervention was a staff-managed graduated prompting system. The other intervention was a self-management package (SMP) made up of sequential picture cues, self-monitoring, feedback on performance after task completion, and public posting of results. Although the prompting system produced moderate improvements in three of the subjects (mean increase of 10%), the SMP was much more effective, producing large gains in three of four subjects (mean increase of 32% over prompting and 42% over baseline), resulting in acceptable levels of performance. Generalization to a no-treatment control task was quite limited. Follow-up indicated maintenance of improved performance over a 12-week interval with three of the four subjects.

Self-monitoring and self-managed reinforcement procedures for improving work productivity of developmentally disabled workers. A review.

This article reviews research that examined self-monitoring and/or self-managed reinforcement procedures for improving and maintaining work productivity of developmentally disabled workers. Seventeen articles were encountered that examined self-monitoring and/or self-administration of reinforcers for productivity. In total, 107 developmentally disabled persons experienced self-management procedures, with diagnoses varying from profoundly to mildly retarded. In most of the studies, work productivity improved during intervention conditions. However, in almost all cases, procedural limitations prevent us from confidently attributing improvements in productivity to the self-management components of the interventions. Moreover, because of practical limitations, we cannot yet offer self-management procedures as a viable strategy to maintain work rates of developmentally disabled workers at acceptable levels throughout typical working days. Additional research is needed that goes beyond the procedural and practical limitations of previous studies.

Expanded assessment for discrimination learning with mentally retarded persons: a practical strategy for research and training.

Practical and reliable instruments to assess basic discriminations by severely and profoundly retarded persons are almost nonexistent. Research findings were reviewed on an assessment instrument, the AVC Discrimination Test, which can be administered in approximately 30 minutes to assess basic position, visual, and auditory discriminations. This test can be used with severely and profoundly mentally retarded persons and is reliable and predictive of client performance in classroom learning, language, and vocational tasks. The advantages of expanding current baseline assessment practices to include the AVC Discrimination Test in research and training programs for persons with mental retardation were discussed.
