The study compared the effectiveness of a traditional training procedure (least-to-most restrictive prompt sequence) and a prescriptive training procedure (utilizing ongoing behavioral assessment data to identify discriminative stimuli) with four severely/multiply handicapped students (ages 11-19). Results indicated both procedures were effective…

Two experiments with five individuals having severe mental retardation identified some problems and limits in training reversals of previously learned discrimination tasks using stimulus control shaping methodology. (DB)

The problem of teaching relational discriminations to people with mental retardation is examined. The limitations of several commonly used teaching procedures are discussed and alternative approaches to simple-discrimination learning are described. Results of two preliminary single-subject studies demonstrating the feasibility of these approaches…

Because disabled learners may profit from procedures using gradual stimulus change, this study utilized a microcomputer to investigate the effectiveness of stimulus equalization, an error reduction procedure involving an abrupt but temporary reduction of dimensional complexity. The procedure was found to be generally effective and implications for…

Two experiments with a total of 17 adolescents or adults with severe mental retardation evaluated the potential of exclusion procedures (selection of an undefined object in comparison with a defined object) as a means of training basic naming skills. Reliable exclusion and naming performance were demonstrated in nearly all subjects. (DB)

The study compared the task demonstration model and the standard prompting hierarchy in training 8 persons (ages 16-21) with moderate or severe mental retardation on a discrimination task. The task demonstration model was found to be superior during both training and generalization phases. (DB)

Four students (ages seven to nine) with moderate mental retardation were successfully taught to name photographs of foods using a progressive time delay procedure. Presentation of the supermarket grocery department as part of the discriminative stimulus was effective in increasing the percentage of correct responding. Some generalization occurred…

This study evaluated the effectiveness of a multimedia computer-based instructional program with four middle school students with moderate/severe mental retardation in establishing match-to-sample skills and generalizing those skills to the natural setting (a grocery store). In vivo probes found mean and median duration to find target items…
