通过对兔子的眼睑条件反射研究了传统的消退程序，即条件刺激（CS）在无条件刺激（US）不呈现的情况下呈现。一项节省测试表明，在常规消退程序之后重新习得的速度比条件刺激和无条件刺激不配对的程序之后更快。这种在重新习得中做出反应的准备状态与初始习得试验的遗留效应有关。当在消退过程中保留无条件刺激时，习得和重新习得是相似的，但当无条件刺激被省略时则不相似。在消退过程中保留无条件刺激的程序在消除或抑制条件刺激和无条件刺激之间的联想联系方面可能比常规的仅条件刺激消退程序更有效。
The traditional extinction procedure in which the CS [conditioned stimulus] is presented in the absence of US [unconditioned stimulus] presentations was examined by eyelid conditioning in rabbits. A savings test demonstrated that the rate of reacquisition is faster after a conventional extinction procedure than after a procedure in which the CS and US have been unpaired. This readiness to respond in reacquisition was related to a carry-over effect from the initial acquisition trials. Acquisition and reacquisition are similar when the US is maintained in extinction but not when it is omitted. Procedures which retain the US during extinction are probably more effective than the conventional CS-alone extinction procedure in eliminating or inhibiting the associative connection between the CS and the US.
