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 to each stimulus were used to identify preferred and nonpreferred stimuli. In Experiment 2, we examined the reinforcing properties of preferred and nonpreferred stimuli by delivering them contingently on the occurrence of arbitrarily selected responses. Results revealed that the preferred stimulus conditions typically produced higher rates of responding than did either the baseline or the nonpreferred stimulus conditions, suggesting that the procedure can be used to assess reinforcer value for individuals with limited behavioral repertoires.
我们评估了一种用于识别重度智力障碍个体潜在强化物的程序。在实验1中，六名受试者被反复暴露于16种刺激之下，对每种刺激的趋近行为被用于识别偏好刺激和非偏好刺激。在实验2中，我们通过在任意选定的反应出现时偶然给予偏好刺激和非偏好刺激，来检验它们的强化特性。结果显示，与基线条件或非偏好刺激条件相比，偏好刺激条件通常能产生更高的反应率，这表明该程序可用于评估行为技能有限的个体的强化物价值。
