We investigated the role of predictable versus unpredictable supervision on the independent task responding of three autistic children. In a predictable supervision condition, the therapist was present in the setting for a regular period of time and then was absent for the remainder of the session. In an unpredictable supervision condition, the therapist's presence was scheduled on a random, intermittent, and unpredictable basis throughout the session. The multiple baseline analysis showed that the unpredictable supervision produced much higher levels of on-task responding during the therapist's absence for all three children. Analysis of work completed during the therapist's absence also favored the unpredictable supervision condition. The results are discussed in relation to the literature on generalization and educational practice.
我们研究了可预测监督与不可预测监督对三名自闭症儿童独立任务反应的作用。在可预测监督条件下，治疗师在设定的时间段内出现，然后在剩余的疗程中缺席。在不可预测监督条件下，治疗师的出现安排在整个疗程中随机、间歇性且不可预测的基础上。多重基线分析表明，对于所有三名儿童，不可预测监督在治疗师缺席期间产生了更高水平的任务反应。对治疗师缺席期间完成的工作的分析也支持不可预测监督条件。结合关于泛化和教育实践的文献对结果进行了讨论。
