Acquisition and performance difference between normal and mentally handicapped adults on a complex assembly task.
Several single studies concerned with work training with the mentally handicapped have been reported in the literature (Bitter & Bolanovich, 1966; Huddle, 1967; Gold, 1969; Screven, Straka & Lafond, 1971). Most have been concerned with issues of acquisition and motivation to perform. No studies have been reported which focus on the evaluation of different techniques of training or which assess rate of acquisition against that of non-handicapped controls. The aim of this experiment is twofold. It uses a complex task, analysed by MTM-2, to enable comparison between the performances of mentally handicapped adults and adults from a 'normal' population, in the acquisition of new work skills. Various strategies of training were compared and the increase in the rate and quality of performance following acquisition was measured for both, in terms of speed and accuracy of production. Results add further support for the notion that the potential of mentally handicapped individuals is commonly underestimated. It is hoped that the findings provide a basis from which further experiments can be developed and evaluated.
