Behavioral contrast and the peak shift, two widely observed phenomena in experiments on successive discrimination learning, were shown to disappear during extended discrimination training. This finding and an analysis of the conditions under which behavioral contrast and the peak shift occur suggested that both phenomena were by-products of emotional responses that resulted from response suppression and that their disappearance after extended discrimination training could be attributed to the dissipation of such emotional responses.
行为对比和峰值转移是连续辨别学习实验中广泛观察到的两种现象，研究表明，在延长的辨别训练过程中，这两种现象会消失。这一发现以及对行为对比和峰值转移出现条件的分析表明，这两种现象都是由反应抑制导致的情绪反应的副产品，而在延长的辨别训练后它们的消失可归因于此类情绪反应的消散。
