常用的实验动物是否像人类一样表现出对社会奖励不平等的厌恶仍然未知。我们检查了老鼠在社会奖励不平等的情况下是否发出 22 kHz 的求救信号。当某个特定的人反复抚摸它们、给它们挠痒痒时，老鼠就会表现出亲和行为。当实验者在社会隔离期间抚摸它们面前的另一只老鼠时，这些老鼠会发出新的叫声，其声学特征不同于在身体压力下发出的叫声，即吹气。在不平等条件下，与接受吹气时相比，老鼠发出的叫声频率更高（~31kHz），持续时间更短（<0.5s）。然而，当老鼠面前有一个有亲和力的人类时，新奇叫声的数量就会减少，老鼠会发出 50 kHz 的叫声，表明食欲状态。这些结果表明，老鼠能够区分社会奖励不平等的条件和实验者的存在，并发出新颖的 31 kHz 叫声。研究人员对暴露于社会奖励不平等的老鼠的超声波发声进行了检查 老鼠对反复触摸它们的特定人类表现出亲和行为 老鼠在隔离和社会不平等条件下发出新颖的 31 kHz 叫声 老鼠可以区分社会不平等条件 生物科学；神经科学；行为神经科学；认知神经科学
Whether commonly used experimental animals show aversion toward inequality of social rewards, as humans do remains unknown. We examined whether rats emitted the 22-kHz distress calls under social reward inequality. Rats showed affiliative behavior for a specific human who repeatedly stroked and tickled them. When experimenter stroked another rat in front of them and during social isolation, these rats emitted novel calls with acoustic characteristics different from those of calls emitted under physical stress, namely air-puff. Under inequality conditions, rats emitted calls with higher frequency (∼31 kHz) and shorter duration (<0.5 s) than those emitted when receiving air-puff. However, with an affiliative human in front of them, the number of novel calls was lower and rats emitted 50-kHz calls, indicative of the appetitive state. These results indicate that rats distinguish between conditions of social reward inequality and the presence of an experimenter, and emit novel 31-kHz calls. Ultrasonic vocalizations in rats exposed to social reward inequality were examined Rats showed affiliative behavior to a specific human who repeatedly touched them Rats emitted novel 31-kHz calls during isolation and social inequality conditions Rats could discriminate social inequality conditions Biological sciences; Neuroscience; Behavioral neuroscience; Cognitive neuroscience
