Cognitive processes have been increasingly implicated in Pavlovian conditioning. Research in the past year has focused on questions of stimulus selection and the internal representation of events and the relations between them. Recent data support negative feedback models of selection that assume conditioning-dependent changes in processing of conditioned and unconditioned stimulus events, and suggest potential neural mechanisms that may underlie these processes. New models of conditioning propose a more detailed representation of individual conditioning episodes than traditionally assumed. The results of investigations into conditional discrimination learning imply a hierarchical organization of event representations, and illustrate the importance of conditioned modulatory processes as distinct from response elicitation.
认知过程在巴甫洛夫条件反射中所起的作用越来越受到关注。过去一年的研究集中在刺激选择问题、事件的内部表征以及它们之间的关系上。最近的数据支持选择的负反馈模型，该模型假设条件刺激和非条件刺激事件处理过程中存在依赖于条件作用的变化，并提出了可能作为这些过程基础的潜在神经机制。新的条件反射模型提出了比传统假设更详细的个体条件反射事件表征。对条件辨别学习的研究结果表明事件表征具有层次结构，并说明了条件调节过程与反应诱发不同的重要性。
