The rabbit nictitating membrane (NM) response underwent successive stages of acquisition and extinction training in both delay (Experiment 1) and trace (Experiment 2) classical conditioning. In both cases, successive acquisitions became progressively faster, although the largest, most reliable acceleration occurred between the first and second acquisition. Successive extinctions were similar in rate. The results challenge contextual control theories of extinction but are consistent with attentional and layered-network models. The results are discussed with respect to their implications for the interaction between cerebellar and forebrain pathways for eyeblink conditioning.
在延迟(实验1)和痕迹(实验2)经典条件反射中,兔瞬膜(NM)反应经历了习得和消退训练的连续阶段。在这两种情况下,连续习得逐渐加快,尽管最大、最可靠的加速发生在第一次和第二次习得之间。连续消退的速率相似。这些结果挑战了消退的情境控制理论,但与注意力和分层网络模型一致。讨论了这些结果对小脑和前脑通路在眨眼条件反射中相互作用的影响。
