用峰值法研究了金鱼条件性反应的获得和维持过程中的反应时序。受试者接受5-或15-S间刺激间隔的光刺激配对。在错综复杂的波峰试验中，45名S被给予条件刺激光，没有给予电击。条件性反应的峰值，即一般活动，大约出现在预期的非条件刺激的时间，活动的可变性，分布是标量的。对会话中活动分布变化的模拟表明，条件反应的时间特征在习得过程中变化很小。这些数据表明，时间是在训练的早期就学会的，与I.P.巴甫洛夫(1927/1960)的“延迟抑制”概念相反，时间的选择是学习什么时候做出反应，而不是学习什么时候不反应。
The peak procedure was used to characterize response timing during acquisition and maintenance of conditioned responding in goldfish. Subjects received light-shock pairings with a 5- or 15-s interstimulus interval. On interspersed peak trials, the conditioned stimulus light was presented for 45 s and no shock was delivered. Peaks in the conditioned response, general activity, occurred at about the time of the expected unconditioned stimulus, and variability in the activity, distribution was scalar. Modeling of the changes in the activity distributions over sessions revealed that the temporal features of the conditioned response changed very little during acquisition. The data suggest that times are learned early in training, and, contrary to I. P. Pavlov's (1927/1960) concept of "inhibition of delay," that timing is learning when to respond rather than learning when not to respond.
