In Experiment 1, rats choosing in an E maze preferred to release a rat standing in a pool of water to dry ground over a rat already standing on dry ground. Five additional experiments showed that the choosing rat's preference for releasing the wet rat was maintained by two separable outcomes: (1) the social contact offered by the released rat and (2) the reinforcing value of proximity to a pool of water. These results call into question Sato et al.'s (Anim Cogn 18:1039-1047, 2015) claim to have demonstrated that a rat's releasing of a wet rat to dry ground is empathically motivated.
在实验1中，在E型迷宫中做出选择的大鼠更倾向于将站在水池中的大鼠放到干燥地面上，而不是把已经站在干燥地面上的大鼠放走。另外五项实验表明，做出选择的大鼠对放走湿鼠的偏好由两个可分离的结果维持：（1）被放走的大鼠提供的社交接触；（2）靠近水池的强化价值。这些结果对佐藤等人（《动物认知》18:1039 - 1047，2015年）声称已证明大鼠将湿鼠放到干燥地面是出于共情动机的说法提出了质疑。
