Using interstimulus intervals (ISIs) of 125, 250, and 500 msec in trace conditioning of the rabbit nictitating membrane response, the offset times and durations of conditioned responses (CRs) were collected along with onset and peak latencies. All measures were proportional to the ISI, but only onset and peak latencies conformed to the criterion for scalar timing. Regarding the CR's possible protective overlap of the unconditioned stimulus (US), CR duration increased with ISI, while the peak's alignment with the US declined. Implications for models of timing and CR adaptiveness are discussed.
在兔瞬膜条件反射的刺激间时程（ISIs）为 125、250 和 500 毫秒的实验中，我们收集了条件反射（CR）的潜伏期、起始时间、时程和峰时。所有的测量都与 ISI 成比例，但只有起始时间和峰时符合标量时间的标准。对于 CR 对条件刺激（US）的可能的保护性重叠，CR 时程随着 ISI 的增加而增加，而峰时与 US 的对齐程度则下降。本文讨论了这些结果对时间模型和 CR 适应性的意义。
