Cognitive processes in extinction Lovibond PFLearn Mem 2004[Sep]; 11 (5): 495-500Human conditioning research shows that learning is closely related to consciously available contingency knowledge, requires attentional resources, and is influenced by language. This research suggests a cognitive model in which extinction consists of changes in contingency beliefs in long-term memory. Laboratory and clinical evidence on extinction is briefly reviewed, and it is concluded that the evidence supports the cognitive position. There is little evidence for a separate, noncognitive conditioning system. The primary implication for neural analysis is that learning and extinction are unlikely to be reducible to direct connections in which one stimulus simply activates or inhibits the memory representation of another. Rather, an adequate neural model will involve the integration of both low-level and high-level systems, including attention, representation of stimulus relations in long-term memory, and a dynamic performance mechanism based on anticipation, not just activation.|Animals[MESH]|Association Learning/*physiology[MESH]|Attention[MESH]|Cognition/*physiology[MESH]|Conditioning, Classical/*physiology[MESH]|Consciousness[MESH]|Extinction, Psychological/*physiology[MESH]|Humans[MESH]|Models, Neurological[MESH] |
