Two experiments using food-container avoidance as an index of neophobia are reported for two strains of laboratory and one strain of wild rats. In Experiment 1 rats were fed from a single familiar container until their consumption had stabilized. Upon replacing the familiar container with a novel container, the latency of all three strains to begin feeding increased. In Experiment 2 rats were offered a choice between a familiar and a novel container containing identical food. Though there was considerable individual variation among the three strains, the wild strain was more reluctant to eat from the novel container than a hooded laboratory strain, which, in turn, was nore reluctant than an albino laboratory strain. Nonetheless, all three strains showed an initial avoidance of the novel container. It was concluded that both wild and laboratory strains are neophobic and that strain differences are ones of degree, not of kind.
报告了两项以对食物容器的回避作为新事物恐惧症指标的实验，实验对象为两种实验室品系大鼠和一种野生品系大鼠。在实验1中，大鼠从单个熟悉的容器中进食，直至其进食量稳定。当用一个新容器替换熟悉的容器后，所有三个品系开始进食的潜伏期都增加了。在实验2中，给大鼠提供了一个装有相同食物的熟悉容器和一个新容器供其选择。尽管这三个品系之间存在相当大的个体差异，但野生品系比有帽实验室品系更不愿意从新容器中进食，而有帽实验室品系又比白化病实验室品系更不愿意。尽管如此，所有三个品系最初都表现出对新容器的回避。得出的结论是，野生和实验室品系都有新事物恐惧症，品系差异只是程度上的，而非本质上的。
