Reciprocity and cooperation are fundamental to human society and are observed in nonhuman primates. Primates are not only sensitive to direct reciprocity and its violation but also indirect reciprocity. Recent studies demonstrated that some primate species adjusted their behavior by observing others' interactions. Capuchin, marmoset, and squirrel monkeys avoided taking food from human actors who behaved nonreciprocally; however, no such empirical evidence among Old World monkeys is available. Here, we show that common marmosets, which are a highly prosocial species, discriminated between human actors who reciprocated in social exchanges and those who did not; however, Japanese monkeys, who are renowned for despotic social relationships, did not. In the reciprocal condition, 2 human actors exchanged food equally, whereas in the nonreciprocal condition, 1 actor (nonreciprocator) ended up with all the food and the other actor with none. The common marmosets avoided receiving food from the nonreciprocator in the nonreciprocal condition. Nevertheless, the Japanese monkeys did not show differential preferences in either condition. These results suggest a crucial role for prosocial tendencies in monkeys' responses to asymmetric exchanges and indicate that third-party social evaluations are not homologous among primates. Further comparative studies with direct comparisons will be required to explore the underlying mechanism of third-party social evaluations.

普通mar猴(Callithrix jacchus)评估人类演员的第三方社交互动,而日本猴(Macaca fuscata)则不这样做。

互惠与合作对人类社会至关重要,在非人类灵长类动物中也有观察到。灵长类不仅对直接互惠及其侵犯敏感,而且对间接互惠敏感。最近的研究表明,某些灵长类动物通过观察他人的相互作用来调节其行为。卷尾猴,mar猴和松鼠猴避免从行为不相干的人类演员那里取食;但是,在旧世界的猴子中没有这样的经验证据。在这里,我们表明,普通mar猴是一种高度亲社会的物种,它们在社会交往中相互交往的人类行为者与没有进行社会交往的人类行为者之间存在区别。但是,以专制社会关系而闻名的日本猴子却没有。在互惠条件下,两个人类参与者平均交换食物,而在非互惠条件下,一个演员(不可互惠者)最终得到了所有食物,另一个演员却一无所有。普通mar猴在不可逆状态下避免从不可逆者那里接收食物。尽管如此,日本猴在这两种情况下都没有表现出不同的偏好。这些结果表明亲社会倾向在猴子对不对称交流的反应中起着至关重要的作用,并表明第三方社会评价在灵长类动物之间并不相同。需要进行直接比较的进一步比较研究,以探索第三方社会评估的潜在机制。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。普通mar猴在不可逆状态下避免从不可逆者那里接收食物。尽管如此,日本猴在这两种情况下都没有表现出不同的偏好。这些结果表明亲社会倾向在猴子对不对称交流的反应中起着至关重要的作用,并表明第三方社会评价在灵长类动物之间并不同源。需要进行直接比较的进一步比较研究,以探索第三方社会评估的潜在机制。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。普通mar猴在不可逆状态下避免从不可逆者那里接收食物。尽管如此,日本猴在这两种情况下都没有表现出不同的偏好。这些结果表明亲社会倾向在猴子对不对称交流的反应中起着至关重要的作用,并表明第三方社会评价在灵长类动物之间并不同源。需要进行直接比较的进一步比较研究,以探索第三方社会评估的潜在机制。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。对不对称交流的回应,并指出第三方社会评价在灵长类动物之间并不相同。需要进行直接比较的进一步比较研究,以探索第三方社会评估的潜在机制。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。对不对称交流的回应,并指出第三方社会评价在灵长类动物之间并不相同。需要进行直接比较的进一步比较研究,以探索第三方社会评估的潜在机制。(PsycINFO数据库记录(c)2019 APA,保留所有权利)。
