尽管人类的亲社会行为通常是由对他人的同理心所驱动的,但目前尚不清楚非灵长类哺乳动物是否也经历了类似的动机状态。为了测试啮齿类动物的移情动机的亲社会行为,将一只自由大鼠放置在一个竞技场中,笼子被困在限制器中。几天之内,这只自由的老鼠故意迅速地打开了笼子,把笼子放了出来。大鼠没有打开空的或含有物体的限制器。即使在奖励性社会接触被阻止的情况下,老鼠也会释放笼中动物。当释放一个笼子与第二个限制器中的巧克力相对抗时,大鼠打开两个限制器,在大多数试验中,分享巧克力。因此,大鼠在应对同种动物的痛苦时表现出亲社会行为,为共情的生物学根源提供了强有力的证据。
Whereas human pro-social behavior is often driven by empathic concern for another, it is unclear whether non-primate mammals experience a similar motivational state. To test for empathically motivated pro-social behavior in rodents, a free rat was placed in an arena with a cagemate trapped in a restrainer. Within days, the free rat acted deliberately and quickly to open the restrainer and free the cagemate. Rats did not open an empty or object-containing restrainer. Rats freed cagemates even when rewarding social contact was prevented. When liberating a cagemate was pitted against chocolate contained within a second restrainer, rats opened both restrainers and in most trials, shared the chocolate. Thus, rats behave pro-socially in response to a conspecific’s distress, providing strong evidence for biological roots of empathy.
