Assessment of stimulus preference and reinforcer value with profoundly retarded individuals.

摘要: We evaluated a procedure for identifying potential reinforcers with profoundly retarded individuals. In Experiment 1, six persons were repeatedly exposed to 16 stimuli, and approach behaviors each stimulus used identify preferred nonpreferred stimuli. 2, we examined the reinforcing properties of stimuli by delivering them contingently on occurrence arbitrarily selected responses. Results revealed that conditions typically produced higher rates responding than did either baseline or conditions, suggesting can be assess reinforcer value individuals limited behavioral repertoires.
