The present study investigated a discrete-trials, operant tracking and a descending-series procedure for the determination of hearing levels with profoundly retarded individuals. These individuals were previously diagnosed as untestable. Following stimulus-control training with errorless discrimination procedures, hearing levels for each individual were examined with both procedures. For P-1 and P-2, the operant tracking procedure was administered following a descending-series procedure. Both were observed to "track" their own hearing levels. For P-3, the operant tracking procedure was administered first, followed by the descending-series procedure. Although P-3 also "tracked" her own hearing level, more variable responding was observed. Nonetheless, the operant tracking procedure proved quite workable and may provide for improved hearing testing with "difficult-to-test" individuals.
本研究调查了一种离散试验、操作性追踪和降序系列程序，用于测定极重度智障个体的听力水平。这些个体之前被诊断为无法测试。在采用无错误辨别程序进行刺激控制训练后，使用这两种程序对每个个体的听力水平进行了检查。对于P-1和P-2，在降序系列程序之后进行操作性追踪程序。观察到两人都能“追踪”自己的听力水平。对于P-3，先进行操作性追踪程序，然后是降序系列程序。虽然P-3也能“追踪”自己的听力水平，但观察到其反应更具变异性。尽管如此，操作性追踪程序证明是相当可行的，并且可能为“难以测试”的个体提供更好的听力测试。
