越来越多的人对儿童如何理解社会交流中的互惠和资源分配中的公平，包括第三方之间的社会交流表现出越来越大的兴趣。尽管在其他物种中有一对一互惠的描述，但非人类是否发现了互惠和第三方之间的互惠违反尚不清楚。在这里，我们展示了卷尾猴区别对待那些在与他人的社会交换中回报的人类和那些不这样做的人类。猴子比非互惠者或部分互惠者更容易接受来自互惠者的食物。然而，当交换不对称是由于一方从更少的商品开始时，最初贫穷的互惠方并没有受到歧视。这些结果表明，在第三方社会交流中判断互惠的认知或情感先决条件至少存在于其他一个灵长类物种中。(C)2012爱思唯尔B.V.保留所有权利。
Increasing interest is being shown in how children develop an understanding of reciprocity in social exchanges and fairness in resource distribution, including social exchanges between third parties. Although there are descriptions of reciprocity on a one-to-one basis in other species, whether nonhumans detect reciprocity and violations of reciprocity between third parties is unknown. Here we show that capuchin monkeys discriminate between humans who reciprocate in a social exchange with others and those who do not. Monkeys more readily accepted food from reciprocators than non-reciprocators or partial reciprocators. However, when exchange asymmetry was due to one partner starting out with fewer goods, the initially impoverished reciprocator was not discriminated against. These results indicate that the cognitive or emotional prerequisites for judging reciprocity in third-party social exchanges exist in at least one other primate species. (C) 2012 Elsevier B.V.
