The preference of 42 Wistar male rats for alcoholic or non-alcoholic solutions of glucose was studied. Preference for the left or right position of drinking tubes did not appreciably influence the choice between the unequal solutions. Within the same strain of rats the majority of the animals had a high and a minority a low level of consumption of the glucose-alcohol solution. These groups were found only under conditions of systematic experimentation and the properties of each group became more marked in the course of these experiments.
研究了42只雄性Wistar大鼠对葡萄糖酒精溶液或葡萄糖非酒精溶液的偏好。饮管左右位置的偏好对不等溶液间的选择没有明显影响。在同一品系的大鼠中，大多数动物对葡萄糖酒精溶液的消耗量较高，少数动物消耗量较低。这些组别仅在系统实验条件下被发现，并且每组的特性在这些实验过程中变得更加明显。
