The effects of distributed feedback and videotape self-monitoring on the productivity of a janitorial trainee with mental retardation.

The participant, an adult worker with moderate mental retardation, had received prior training in cleaning bathroom, hall, and office sites in a community-based competitive work setting, but demonstrated substandard productivity. An intervention program was designed, consisting of (a) videotape-based self-monitoring, and (b) distributed verbal feedback and breaks which were systematically reduced over time. Sequential application of the intervention to the three cleaning sites resulted in the person's increased productivity in each site. Results are discussed in terms of the components of the training package.
