Delay-reduction theory states that the effectiveness of a stimulus as a conditioned reinforcer may be predicted most accurately by the reduction in time to primary reinforcement correlated with its onset. We review support for the theory and then discuss two new types of experiments that assess it. One compares models of choice in situations wherein the less preferred outcome is made more accessible; the other investigates whether frequency of conditioned reinforcement affects choice beyond the effect exerted by frequency of primary reinforcement.
延迟减少理论认为，作为条件强化物的刺激的有效性，可以通过与其出现相关的初级强化时间的减少来最准确地预测。我们回顾了对该理论的支持，然后讨论了评估它的两种新型实验。一种是在不太偏好的结果更容易获得的情况下比较选择模型；另一种是研究条件强化的频率是否会在初级强化频率产生的影响之外影响选择。
