本文演示和分析了自发恢复的刺激控制后，向前和向后的条件性抑制制备大鼠。实验我发现。在一阶条件反射，强大的前向阻断和衰减后的保留间隔。实验2表明，在感觉预处理，反应恢复后，向前和向后的封锁。此外，本实验的结果表明，响应恢复到阻塞刺激不能解释的一个受损状态的阻塞刺激后的保留间隔。实验3也是在感觉预处理中，表明实验2中向前和向后阻滞后的自发恢复是由于在用阻滞刺激测试期间阻滞刺激的表征的联合激活受损。虽然没有当代的联想学习模型可以解释这些结果，R。R.米勒和L. D. Matzel（1988）的比较器假设被提出来这样做。
This article demonstrates and analyzes spontaneous recovery of stimulus control following both forward and backward blocking in a conditioned suppression preparation with rats. Experiment I found. in first-order conditioning, robust forward blocking and an attenuation of it following a retention interval. Experiment 2 showed, in sensory preconditioning, recovery of responding following both forward and backward blocking. Also, the results of this experiment indicated that response recovery to the blocked stimulus cannot be explained by an impaired status of the blocking stimulus after a retention interval. Experiment 3, also in sensory preconditioning, suggested that spontaneous recovery following both forward and backward blocking in Experiment 2 was due to impaired associative activation of the blocking stimulus' representation during testing with the blocked stimulus. Although no contemporary model of associative learning can explain these results, a modification of R. R. Miller and L. D. Matzel's (1988) comparator hypothesis is proposed to do so.
