Profoundly retarded multiply handicapped children were placed in a situation where auditory stimulation was made contingent on a visually directed level-pulling response. Two experiments were performed. In the first, a technique for establishing an effective reinforcer from a range of possible reinforcing stimuli was evaluated. In the second experiment, a multiple schedule was used to compare the effectiveness of a reinforcer whose efficacy was established in Experiment 1 with a second auditory stimulus. The selection of auditory reinforcers and an evaluation of their relative potency was achieved using these techniques. The results show the feasibility of systematic measurement of operant-conditioning effects with very severely handicapped subjects in a laboratory situation. The information gained concerning the effectiveness of auditory reinforcers has implications for behavior-modification programs with these children.
重度智力迟钝且多重残疾的儿童被置于一种情境中，在这种情境下，听觉刺激取决于视觉引导的水平拉动反应。进行了两项实验。在第一项实验中，评估了一种从一系列可能的强化刺激中建立有效强化物的技术。在第二项实验中，使用了多重时间表来比较在实验1中确定其效力的强化物与第二种听觉刺激的有效性。通过这些技术实现了听觉强化物的选择及其相对效力的评估。结果表明，在实验室情境中对非常严重残疾的受试者进行操作性条件作用效果的系统测量是可行的。所获得的关于听觉强化物有效性的信息对针对这些儿童的行为矫正计划具有启示意义。
