进行了三个实验来检查暴露于中毒同种动物对大鼠随后食物厌恶的影响。在实验 1A 中，对可可味食物产生厌恶反应的老鼠被暴露于吃过相同食物的中毒同种动物中。在随后的选择测试中，动物增加了对那种食物的厌恶。这些结果在实验 1B 中得到了再次证实，其中使用肉桂味食物作为刺激。在实验2中，受试者首先接触中毒的同种动物，然后适应同种动物吃过的食物。在测试中，他们没有表现出对这种食物越来越厌恶的迹象。
Three experiments were conducted to examine the effects of exposure to a poisoned conspecific on subsequent food aversion in rats. In Experiment 1A, rats that had been aversively conditioned to a cocoa-flavored food were exposed to a poisoned conspecific that had eaten the same food. On the subsequent choice test, the animals increased their aversion to that food. These results were reconfirmed in Experiment 1B, in which a cinnamon-flavored food was used as the stimulus. In Experiment 2, subjects were first exposed to a poisoned conspecific and then conditioned to the food which the conspecific had eaten. On the test, they showed no sign of increased aversion to that food.
