在5个实验中的作用，激励学习工具性能的转变后，主要动机进行了检查。在实验1和实验2中，训练大鼠在低剥夺状态下进行由丸粒或麦芽糖糊精加强的工具性动作，然后转移到高剥夺状态并进行灭绝测试。这种剥夺的转变只有在动物在工具训练之前在高度剥夺状态下接触过兴奋剂时才能提高表现。实验3、4和5研究了在高剥夺状态下的反向转移训练和在低剥夺状态下的测试，并且发现，同样地，如果动物先前在低剥夺状态下暴露于反向转移，则性能仅对这种转移敏感。这些实验支持的结论是，工具性能后重新评估的评价者取决于一个过程的激励学习。
In 5 experiments the role of incentive learning in instrumental performance following a shift in primary motivation was examined. In Experiments 1 and 2 rats trained to perform an instrumental action reinforced by either pellets or maltodextrin when in a low-deprivation state were shifted to a high-deprivation state and tested in extinction. This shift in deprivation increased performance only if the animals had been exposed to the reinforcer in the high-deprivation state prior to instrumental training. Experiments 3, 4, and 5 examined the reverse shift training in a high-deprivation state and testing in a low-deprivation state, and found, similarly, that performance was only sensitive to this shift if animals were previously exposed to the reinforcer while in the low-deprivation state. These experiments support the conclusion that instrumental performance following revaluation of the reinforcer depends on a process of incentive learning.
