A demonstration of generalization of performance across settings, materials, and motor responses for students with...

A treatment package, consisting of multiple exemplar training and community-based instruction, was evaluated for its effectiveness in teaching four students with profound mental retardation and multiple disabilities to participate in two sets of community-living tasks. All training took place in community settings, and each student demonstrated improved performance on at least one task set. In addition, all students demonstrated improved performance on a series of tasks selected to assess generalization of performance across settings, materials, and/or motoric responses required to complete the target task. Maintenance of performance over a 4- to 5-month period was assessed and achieved for two of the students. The results of this investigation are discussed in terms of the implications for programming for students with profound mental retardation.
