我们调查合作解决问题的合作繁殖棉顶绢毛猴，Saguinus俄狄浦斯，在这个物种的合作行为的认知基础进行评估，并与其他猿类和猴子的能力进行比较。使用透明的装置，其需要在装置的相对端处延伸两个手柄以获取奖励。两个把手都有阻力，所以两只绢毛猴必须同时行动才能得到奖励。与之前的几项合作研究相反，两种绢毛猴都因同时拉动而获得奖励。两个实验的结果表明，棉顶绢毛猴（1）比以前研究的许多其他物种有更高的成功率和效率，（2）调整拉行为的存在或不存在的合作伙伴，（3）自发地发展持续的拉技术来解决任务。这些发现表明棉顶绢毛猴理解合作伙伴在这项合作任务中的作用，这种认知能力被广泛认为只有类人猿才有。绢毛猴的合作社会系统，直观的设计，以及对参与者双方的奖励可以解释绢毛猴的表现。(C)2004年，动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
We investigated cooperative problem solving in unrelated pairs of the cooperatively breeding cottontop tamarin, Saguinus oedipits, to assess the cognitive basis of cooperative behaviour in this species and to compare abilities with other apes and monkeys. A transparent apparatus was used that required extension of two handles at opposite ends of the apparatus for access to rewards. Resistance was applied to both handles so that two tamarins had to act simultaneously in order to receive rewards. In contrast to several previous studies of cooperation, both tamarins received rewards as a result of simultaneous pulling. The results from two experiments indicated that the cottontop tamarins (1) had a much higher success rate and efficiency of pulling than many of the other species previously studied, (2) adjusted pulling behaviour to the presence or absence of a partner, and (3) spontaneously developed sustained pulling techniques to solve the task. These findings suggest that cottontop tamarins understand the role of the partner in this cooperative task, a cognitive ability widely ascribed only to great apes. The cooperative social system of tamarins, the intuitive design of the apparatus, and the provision of rewards to both participants may explain the performance of the tamarins.
