BACKGROUND One issue that has received relatively little attention in the analyses of the neophobic responses to a novel flavor is the influence of the context in which the flavor is first encountered, along with the effect of this context on the habituation of neophobia when the flavor is repeatedly consumed. Considering the predictions of the Contextual Safety Hypothesis, which proposes that the previous appetitive or aversive history of the context will modulate the intensity of neophobia and its habituation, we designed an experiment to evaluate the role played by the context in neophobia and its habituation to a new flavor. METHOD Male Wistar rats had access to a new flavor solution (0.1% sacharin) in presence of a context previously submitted to a treatment intended to turn it into appetitive, aversive or merely familiar. An additional group of rats received the new flavor in their home cages. RESULTS After four days of saccharin exposure, those animals in the Appetitive and Home conditions showed significant faster neophobia habituation as compared to those in the Aversive and Familiar groups. CONCLUSIONS These results revealed the potential applied value of using contextual manipulations to promote healthy eating behavior both in animals and humans.

上下文属性调节风味新恐惧症习惯。

背景 在对新口味的恐新症反应的分析中，一个相对较少受到关注的问题是首次遇到该口味的环境的影响，以及该环境对新口味习惯的影响。反复食用。考虑到情境安全假说的预测，即之前对情境的食欲或厌恶历史将调节恐新症的强度及其习惯，我们设计了一个实验来评估情境在恐新症中所起的作用及其习惯新口味。方法 雄性 Wistar 大鼠在存在先前提交给旨在将其变成食欲、厌恶或仅仅熟悉的治疗的环境的情况下获得一种新的风味溶液（0.1% 糖精）。另一组老鼠在它们的笼子里接受了这种新口味。结果 在糖精暴露四天后，与厌恶和熟悉组中的动物相比，食欲和家庭条件下的那些动物表现出明显更快的新恐惧症习惯。结论这些结果揭示了使用上下文操作来促进动物和人类健康饮食行为的潜在应用价值。
