使用实验诱导的合作任务，作者调查了簇毛卷尾猴(Cebus Apella)是否与人类分享以下3个合作特征：分工、交流和互惠利他主义。在实验1中，作者训练单个猴子执行必要的动作序列以获得奖励，并对它们进行配对测试，以评估它们是否能够通过自发地划分动作序列来解决任务。所有的配对都解决了这项任务。在实验2中，猴子在合作任务和不需要伙伴帮助的任务中工作。在前一项任务中，他们注视对方的时间明显长于在后一项任务中，但无法确定交流意图。在实验3中，2名参与者中只有1人在每次试验中获得奖励。当猴子在交替试验中角色颠倒时，它们保持合作。他们的合作表现出了分工；结果表明任务相关的沟通和互惠的利他主义。
Using an experimentally induced cooperation task, the authors investigated whether tufted capuchin monkeys (Cebus apella) share the following 3 characteristics of cooperation with humans: division of labor, communication, and reciprocal altruism. In Experiment 1, the authors trained individual monkeys to perform the necessary sequence of actions for rewards and tested them in pairs to assess whether they could solve the task by spontaneously dividing the sequence of actions. All pairs solved this task. In Experiment 2, monkeys worked in the cooperation task and a task requiring no partner help. They looked at the partner significantly longer in the former task than in the latter, but communicative intent could not be determined. In Experiment 3, only 1 of 2 participants obtained a reward on each trial. Monkeys maintained cooperation when their roles were reversed on alternate trials. Their cooperative performances demonstrated division of labor; results suggest task-related communication and reciprocal altruism.
