Movement training

Abstract

Trainer initiated reinforcement and client self-monitoring have been used successfully to increase the vocational productivity of individuals with moderate and severe mental retardation. Some previous research, however, has reported cases in which reinforcement strategies had minimal influence on productivity. The current study introduced reinforcement and self-monitoring sequentially in an attempt to improve the productivity levels of five clients with moderate and severe mental retardation in an adult development center. In a subsequent alternating treatments phase, the self-monitoring was compared to self-monitoring with movement training--prompting through a task analysis of the most efficient movements to perform a task. In a final phase, the most effective treatment of the alternating treatments for each subject was replicated across sessions. Four of the five subjects responded minimally to trainer initiated reinforcement or self-monitoring but showed improvement with movement training. This increase was replicated across sessions for three of these four subjects. A fifth subject increased productivity substantially with reinforcement, maintained the increase with self-monitoring, and replicated the increase across sessions with self-monitoring alone. This fifth subject did not increase productivity with movement training.
