Four experiments involving 18 individuals (ages 14-55) with profound multiple handicaps found that 12 stimuli used in a preference assessment represented a comprehensive stimulus set for identifying preferences, though the utility of the set could sometimes be enhanced by caregiver opinion. Results also indicated that preferences identified were…

The applicability of two reinforcer assessment procedures to children with developmental disabilities and visual impairments was evaluated. Greater differentiation between stimuli occurred with a choice procedure than with a preference procedure. Measurement of compliance and responding rate in adaptive skill training confirmed that the choice…

A choice assessment was used to categorize reinforcers as high, middle, and low preference with 4 males (ages 7 to 19) with multiple disabilities including severe/profound mental retardation. High-preference stimuli consistently functioned as reinforcers for all subjects whereas low-preference stimuli did not function as reinforcers. (Author/DB)

A systematic assessment procedure successfully identified stimulus preferences of seven profoundly and multiply handicapped individuals (ages 12-34). Preference rankings based on caregiver opinion did not consistently coincide with these results. Systematically assessed student preferences were a likely, though not certain, source of reinforcing…

Three individuals with multiple severe disabilities were taught an appropriate response to problem behaviors, but the response was less efficient than the problem behavior on physical effort, schedule of reinforcement, or stimulus-reinforcer time delay. The response did not compete successfully with the problem behaviors until a new, more…
