Effects of age and interstimulus interval (ISI) were examined in eyeblink classical conditioning with a trace paradigm. Sixty young adults were trained in Experiment 1 with 6 interstimulus intervals (ISIs): 400, 900, 1,200, 1,500, 1,800, and 2,100 ms. The purpose was to find an ISI value for humans that would result in nonoptimal acquisition. ISIs of 1,200 ms and longer were nonoptimal. Adults aged 17-81 years were trained in Experiment 2 with a nonoptimal 1,800-ms ISI in the trace paradigm. Young and middle-aged subjects demonstrated equivalent levels of acquisition, and only older subjects conditioned more poorly. Aging appears to affect conditioning in the long-ISI trace paradigm as well as in the short-ISI delay paradigm.
在采用痕迹范式的眨眼经典条件反射实验中，研究了年龄和刺激间隔（ISI）的影响。在实验1中，60名年轻人接受了6种刺激间隔（ISI）的训练：400、900、1200、1500、1800和2100毫秒。目的是找到一个会导致非最佳习得的人类ISI值。1200毫秒及更长的ISI是非最佳的。在实验2中，17 - 81岁的成年人在痕迹范式中接受了非最佳的1800毫秒ISI训练。年轻和中年受试者表现出相当的习得水平，只有老年受试者的条件反射较差。衰老似乎会影响长ISI痕迹范式以及短ISI延迟范式中的条件反射。
