Abstract

Retrieval of a flavor-illness association has been found to show contextual dependence when the association is learned after a nontarget flavor-illness association has been extinguished in what has been named as the extinction makes acquisition context-specific (EMACS) effect. Four experiments were designed to further explore the EMACS effect in conditioned taste aversion. Experiments 1 and 2 replicated the EMACS effect using rats that did not experience extinction, and rats that underwent extinction of a different flavor as controls. Experiments 3 and 4 found that the experience of extinction with the nontarget Flavor X in a given context (A) led to context-specificity of performance to the target Flavor Y both, when Y was trained in a highly familiar context (B) and tested in the context where X had been trained (Context A, Experiment 3), and when the test was conducted in a less familiar context (C) where no cues or outcomes were presented before (Experiment 4). These results are consistent with the idea that the experience of extinction encourages organism's attention to the contexts, making retrieval of new learning context-specific.

消退使习得在条件性味觉厌恶中具有情境特异性,而不管习得和测试发生的情境如何。
在非目标风味-疾病关联消失后,风味-疾病关联的检索被发现显示出上下文依赖性,这种关联被称为习得情境特异性(EMACS)效应的消失。我们设计了四个实验来进一步探讨EMACS在条件性味觉厌恶中的作用。实验1和2用没有经历过灭绝的大鼠和经历过不同味道灭绝的大鼠作为对照,复制了EMACS效应。实验3和4发现,当Y在高度熟悉的环境中训练(B)和X在训练的环境中测试(背景a,实验3)时,在给定环境(a)中对非目标味道X的消失体验导致了对目标味道Y的情境特异性表现。以及在不太熟悉的环境(C)中进行测试时(实验4),在此之前没有提示或结果(实验4)。这些结果与灭绝的经历鼓励生物体对环境的注意,使新学习的检索特定于环境的观点一致。(PsycINFO数据库记录(c) 2018 APA,版权所有)。
