Rats trained on a series of 16 novel 2-odor discrimination tasks using a 10-s intertrial interval (ITI) rapidly improved in performance and made only 0-3 errors by the end of the test series. They were then tested on other novel pairs of odors, but with a 10- and a 30-min interval between trials. There was no decrement in performance accuracy in the longer ITI tests and, in most cases, criterion performance was achieved after making zero or 1 error after the first (information) trial. These results demonstrate that rats have the capacity to remember for at least 30 min whether a single brief presentation of a novel odor was followed by a reward.
在一系列16个新颖的双气味辨别任务中接受训练的大鼠，使用10秒的试验间隔（ITI），其表现迅速提高，到测试系列结束时仅犯0至3次错误。然后，它们在其他新颖的气味对中进行测试，但试验之间的间隔为10分钟和30分钟。在较长ITI测试中，表现准确性没有下降，并且在大多数情况下，在第一次（信息）试验后犯0次或1次错误后就达到了标准表现。这些结果表明，大鼠有能力记住至少30分钟，即一种新颖气味的单次短暂呈现之后是否有奖励。
