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.
在四项实验中，我们研究了情境线索在大鼠新事物恐惧症习惯化过程中的作用。实验1表明，在一种情境（A）中，一系列呈现过程中新型口味的摄入量增加，但当该口味随后在第二种新型情境（B）中呈现时，摄入量下降。在实验2和3中，实验对象同样在情境A中接触了一种口味，但也对测试情境B进行了熟悉。这些实验对象在测试时，无论该口味是在情境A还是情境B中呈现，都以相同的意愿食用。实验4重复了实验1的结果，并且还表明新型口味的摄入量不受其是在新型情境还是熟悉情境中呈现的影响。讨论了情境的新颖性或熟悉性可能与口味的新颖性或熟悉性相互作用的几种机制。
