Formal models that explain how animals learn associations between stimuli have enjoyed considerable success, and have even been identified with neurophysiological mechanisms. Theoretical analysis of the opposite, though equally important, form of learning - that two stimuli are not associated - lags far behind, due to fundamental methodological confounds that plague research on this topic. This project investigates two instances of this learning: extinction and latent inhibition. Using a new procedure that avoids earlier confounds, we will describe and compare the processes underlying extinction and latent inhibition. This research will represent a major breakthrough in our understanding about fundamental processes in learning.

解释动物如何学习刺激之间的关联的正式模型已经取得了相当大的成功，甚至已经被确定为神经生理学机制。对学习的相反形式--两种刺激不相关--的理论分析虽然同样重要，但却远远落后，这是由于困扰这一主题研究的基本方法论混乱。这个项目研究了这种学习的两个例子：消退和潜在抑制。使用一个新的程序，避免早期的混乱，我们将描述和比较潜在的灭绝和潜伏抑制的过程。这项研究将代表我们对学习基本过程理解的重大突破。
