A consistent finding with respect to retarded individuals is that they exhibit prolonged responding during the extinction phase of a classical eyelid-conditioning procedure relative to nonretarded individuals. The present investigation was carried out to determine whether the failure of retarded individuals to cease conditioned responding is due to a motor inhibitory deficit or to the inability to form a cognitive inhibitory set. The results indicated that, with prompting, the retarded subjects were able to inhibit the conditioned response, thereby eliminating the motor inhibitory deficit explanation for the continued conditioned responding. The data further suggested that the failure to form a cognitive inhibitory set may be related to the inability of retarded individuals to produce effective mediators.
关于智力迟钝个体的一个一致发现是，相对于非智力迟钝个体，他们在经典眼睑条件反射程序的消退阶段表现出持续的反应。本研究旨在确定智力迟钝个体未能停止条件反应是由于运动抑制缺陷还是无法形成认知抑制定势。结果表明，在提示下，智力迟钝的受试者能够抑制条件反应，从而排除了对持续条件反应的运动抑制缺陷解释。数据进一步表明，未能形成认知抑制定势可能与智力迟钝个体无法产生有效的中介物有关。
