A response-restriction analysis of stereotypy in adolescents with mental retardation: implications for applied behavior analysis.
The behavior of 4 adolescents with severe or profound mental retardation was evaluated in the presence of four sets of materials during periods of unstructured leisure activity. Functional engagement with the materials, stereotypic engagement with the materials, stereotypy without interaction with the materials, and other aberrant behaviors were recorded. Across a series of experimental conditions, the number of sets of materials was reduced from four to one by eliminating the set most frequently manipulated in each preceeding condition. In the final condition, four sets of materials were again made available for manipulation. The procedures replicated Green and Striefel's (1988) response-restriction analysis of the activity preferences and play behaviors of children with autism. In general, the results of the present experiment replicate those of Green and Striefel in that reallocation of responding was idiosyncratic and unpredictable as sets of materials were removed. Nevertheless, the results provided insight into how responding might be reallocated if it were restricted through behavioral interventions rather than by restriction of access. Thus, the results are discussed with respect to how response-restriction analyses may be useful in identifying topographies of behavior that could be included in differential reinforcement contigencies that are designed to affect stereotypic behavior and in the selection and arrangement of environmental stimuli to minimize the presence of evokers of stereotypy.
