Abstract
The effects of training using tactile (physical guidance), visual (modeling), auditory (verbal instructions) prompting, and a combination of all three methods were compared by teaching vocational rehabilitation clients the construction of four assembly tasks. Clients learned to assemble a movie projector, a carburetor, a bicycle brake, and a lawn mower engine on four successive days by the four prompting methods in a counterbalanced design. Using auditory prompts alone resulted in significantly more time to criterion and total errors than the other three methods. Tactile, visual, and combination prompting methods were not significantly different. Retention data indicated no difference among the four methods, but in a relearning phase, the auditory prompting method again produced more errors to acquisition.
