Seven long-tailed macaques (Macaca fascicularis) were trained by threats not to drink from a juice nipple as long as an experimenter was facing them. However, they were allowed to drink when the experimenter was standing with his or her back turned. During transfer tests, the monkeys had a choice between 2 juice nipples, one uncovered and the other hidden from the experimenter by a wooden screen, while the experimenter was facing them. We tested whether the monkeys would then prefer to drink behind the screen, thus demonstrating that they transferred knowledge acquired during training. Results did not yield a significant outcome, suggesting that the macaques did not transfer the observable "experimenter's visible open eyes" and that they did not take the experimenter's perspective.
七只食蟹猴（猕猴属）通过威胁训练，只要实验者面对它们，就不许从果汁乳头饮水。然而，当实验者背向它们站立时，它们被允许饮水。在转移测试中，当实验者面对猴子时，猴子可以在两个果汁乳头之间进行选择，一个未被遮盖，另一个被木屏风遮挡，使实验者看不到。我们测试猴子是否会选择在屏风后饮水，以此证明它们转移了训练期间获得的知识。结果没有产生显著结果，这表明猕猴没有转移可观察到的“实验者可见的睁开眼睛”这一信息，并且它们没有采取实验者的视角。
