在四个实验中，我们研究了上下文线索在大鼠新恐惧症习惯化中的作用。实验1表明，在一种情况下（A），一种新风味的消费在一系列呈现中增加，但当该风味随后在第二种新的情况下（B）呈现时下降。在实验2和3中，受试者再次接受在情境A中的风味暴露，但也熟悉测试情境B。这些受试者以同样的意愿食用这种味道，无论它是在测试的背景A还是背景B中呈现。实验4重复了实验1的结果，并且还表明，新风味的消费不受其是否在新的或熟悉的背景下呈现的影响。讨论了上下文的新奇或熟悉性可能与风味的新奇或熟悉性相互作用的几种机制。
In four experiments we investigated the role of contextual cues in the habituation of neophobia in rats. Experiment 1 showed that the consumption of a novel flavour increased across a series of presentations in one context (A) but fell when the flavour was subsequently presented in a second, novel, context (B). In Experiments 2 and 3, subjects again received exposure to a flavour in context A, but also were familiarized with the test context, B. These subjects consumed the flavour with equal readiness, whether it was presented in Context A or in Context B at test. Experiment 4 replicated the results of Experiment 1 and also showed that the consumption of a novel flavour was not influenced by whether it was presented in a novel or a familiar context. Several mechanisms by which the novelty or familiarity of the context might interact with the novelty or familiarity of the flavour were discussed.
