A central theme in our studies of primate social behavior at the Yerkes RPRC is reciprocal altruism. The reciprocity studies focus on food-sharing in capuchin monkeys (chimpanzees are also being studied under the general support of our chimpanzee project "Behavioral and Veterinary Approaches to Primate Breeding"). The capuchin study is of an experimental nature, in which one monkey of a pair receives food while separated from the other by mesh. The food possessor often shares with the other through the mesh. These monkeys live normally in a social group pairs are removed for brief test periods. After first having studied sharing behavior itself, and the degree to which it occurs reciprocally, the purpose of the current study is to investigate to what extent, if at all, food sharing is used by capuchins as a payment for cooperation. For reciprocal exchange to occur it would seem necessary that individuals not only assist conspecifics, but also take notice of received assista nce. The central question here is whether rewards obtained through cooperation are more readily shared than rewards obtained through individual effort. Pairs of monkeys are presented with tasks in which one subject cannot obtain food unless assisted by the other. Food is placed outside a test chamber on a tray too heavy for a single monkey to pull close. If both monkeys pull together, however, one of them will obtain food that subsequently can be shared with the other. Our studies have shown that, contrary to reports in the literature, capuchins cooperate (i.e. their joint action is not a product of random activity, but closely coordinated), and detailed analyses pertaining to the above question are currently in progress.

我们对灵长类动物社会行为研究的一个中心主题是， Yerkes RPRC是互惠利他主义。 互惠研究的重点是 卷尾猴的食物分享（黑猩猩也在研究中 在我们的黑猩猩项目“行为和 灵长类动物繁殖的兽医方法”）。 卷尾猴的研究 一种实验性质，一对猴子中的一只接受食物 同时通过网与另一个分离。 食物拥有者经常 通过网格与另一个共享。 这些猴子生活正常 在一个社会群体中，在短暂的测试期间，配对被移除。 后 首先研究了分享行为本身， 如果发生这种情况，目前研究的目的是 调查在多大程度上，如果有的话，食物共享被使用， 作为合作的报酬 为了相互交换， 出现这种情况似乎不仅需要个人帮助， 同类，但也注意到收到的援助。 的 这里的核心问题是，通过合作获得的回报 比通过个人获得的奖励更容易分享 努力 研究人员向成对的猴子提出了一些任务， 受试者不能获得食物，除非得到另一方的帮助。 食物是 放置在测试室外的托盘上，托盘对于单个猴子来说太重 拉近距离 但是，如果两只猴子齐心协力， 将获得随后可以与他人分享的食物。 我们 研究表明，与文献中的报道相反， 卷尾猴合作（即他们的联合行动不是一个产品， 随机活动，但密切协调）和详细分析 有关上述问题的调查正在进行中。 资金 NSF /IBN 9603923 $31，645 03/01/1997 - 02/28/2000出版物韦弗， A.
