近年来，通过嗅觉线索而不是视觉或听觉线索进行训练，老鼠可以表现出“类似灵长类动物”的学习集形成学习能力，这一说法引起了人们极大的兴趣。在这项研究中，通过使用一系列实验和控制程序来详细评估这一说法，以确定老鼠是否确实发展出了抽象的“赢-停留，输-转移”策略，该策略是猴子学习集形成的基础。我们在此报告，虽然暴露于一系列新颖的嗅觉辨别问题会导致学习速度逐渐提高，但这并不是快速学习发展的必要条件。此外，即使老鼠在嗅觉逆转学习中未能表现出逐步改善，也能快速学习新的嗅觉辨别问题。这些发现均表明，尽管嗅觉学习可能很快，但学习集的形成并不是通过一系列短问题就能形成的。
The claim that rats can demonstrate the 'primate-like' learning capacity of learning set formation when trained with olfactory cues, rather than visual or auditory cues, has generated considerable interest in recent years. In this study, the claim is evaluated in detail by using a series of experimental and control procedures to determine whether rats do indeed develop the abstract 'win-stay, lose-shift' strategy which underlies learning set formation in monkeys. We report here that although exposure to a series of novel olfactory discrimination problems gives rise to progressive improvement in the rate of learning, it is not a necessary condition for the development of that rapid learning. Furthermore, even rats which fail to display progressive improvement in olfactory reversal learning show rapid learning on novel olfactory discrimination problems. Each of these findings suggests that although olfactory learning may be rapid, learning set formation does not occur over a short series of problems.
