自发恢复与训练-消退间隔成反比

四个实验发现，初始条件作用与消退之间的时间间隔越短，消退后自发恢复的幅度越大。实验1和2对大鼠采用巴甫洛夫杂志方法，实验3对大鼠采用仪器训练方法，实验4对鸽子采用手势跟踪方法。这些结果并没有被许多自发恢复的描述所预料到，这些描述将其归因于在灭绝期间发生的学习能力的衰退。
Four experiments found the magnitude of spontaneous recovery after extinction to be greater with a shorter interval between initial conditioning and extinction. Experiments 1 and 2 used a Pavlovian magazine approach procedure with rat subjects, Experiment 3 used an instrumental training procedure with rats, and Experiment 4 used a sign-tracking procedure with pigeons. These results are not anticipated by many accounts of spontaneous recovery that attribute it to the fading of learning that occurred during extinction.
