The effectiveness of contingent restraint in reducing stereotyped body rocking of profoundly retarded subjects was investigated to determine (a) whether restraint reduced stereotyped body rocking and (b) the degree to which the effectiveness of restraint depended upon where in the behavioral sequence it was administered. Results showed that restraint, in comparison to no restraint, reduced the amount of body rocking. Also, restraint was judged to be generally more effective if it were applied when the subject was bent over in the middle of the response sequence rather than administered while the subject was sitting upright at the end of the response sequence. The results were interpreted in terms of response chaining and postural feedback. Implications for the utilization of physical restraint as a behavioral intervention were discussed.
研究了偶然约束在减少重度智力迟钝受试者刻板身体摇晃方面的有效性，以确定：（a）约束是否减少了刻板身体摇晃；（b）约束效果在多大程度上取决于其在行为序列中的施用位置。结果表明，与无约束相比，约束减少了身体摇晃的量。此外，如果在反应序列中间受试者弯腰时施加约束，而不是在反应序列结束时受试者直立坐着时施加约束，通常会被认为更有效。根据反应链和姿势反馈对结果进行了解释。讨论了将身体约束作为一种行为干预措施的应用意义。
