研究了人类饲养的卷尾猴（Cebus apella）的社会学习，使用人工水果来模拟灵长类动物面临的自然觅食问题。每个受试者观察到一个人体模型以两种可选的方式（“变形”）中的一种打开水果上的三个主要成分。卷尾猴在不同程度上复制了用于打开任务的一个部分的替代技术（戳和拉，同时拧出一对光滑的塑料螺栓），但没有复制其他两个部分。从受试者在门闩上的动作中，独立编码员可以识别出他们所目睹的变形，并且他们观察到与演示者的行为有一定程度的匹配，这与简单的模仿或物体运动的重现是一致的（a通过观察B如何移动物体或物体的一部分来学习）。因此，这些卷尾猴比最近认为的猴子具有更复杂的社会学习能力。
Social learning in II human-raised capuchin monkeys (Cebus apella) was investigated using an artificial fruit that was designed as an analogue of natural foraging problems faced by primates. Each subject observed a human model open each of 3 principal components on the fruit in 1 of 2 alternative ways ("morphs"). The capuchin monkeys reproduced, to differing extents, the alternative techniques used for opening 1 component of the task (poking vs; pulling while twisting out a pair of smooth plastic bolts) but not the other 2. From the subjects' actions on the bolt latch, independent coders could recognize which morph they had witnessed, and they observed a degree of matching to the demonstrator's act consistent with simple imitation or object movement reenactment (A learns from watching B how an object, or parts of an object, move). Thus, these capuchins were capable of more complex social learning than has been recently ascribed to monkeys.
