三只被训练做出请求手势的松鼠猴在人类助手的存在下进行了测试，人类助手的视觉注意力在不同的试验中有所不同。当一个盘子里有食物，而旁边有一个空盘子时，猴子们会压倒性地指向前者，不管助手的目光在哪里。当她看着他们时，当她试图让他们共同注意时，她一边看着助手一边指着（“监视”）。当只有一个盘子的时候，如果盘子是空的，如果没有助手在场，猴子就不会做手势。当助理与他们对视时，他们的手势更多。而且，当助手的注意力从盘子或者天花板转移到猴子身上时，猴子们也会重新开始指指点点，加强对助手的监控。这是第一次在新世界的猴子中展示这种灵活的有意沟通的请求手势。Am.

Three squirrel monkeys, trained to make a requesting gesture, were tested in the presence of a human assistant whose visual attention varied across trials. When food was available in one dish and an empty dish was nearby, the monkeys pointed overwhelmingly toward the former, regardless of where the assistant was looking. Looking at the assistant while pointing ("monitoring") peaked when she looked at them and when she attempted to engage them in joint attention. When only one dish was present, the monkeys refrained from gesturing if it was empty and if no assistant was present. They gestured more when the assistant made eye contact with them. Furthermore, when the assistant's focus of attention switched from the dish or the ceiling to the monkeys, the latter resumed pointing and increased their monitoring of the assistant. This is the first demonstration of such flexible use of an intentionally communicative requesting gesture in New World monkeys. Am. J. Primatol. 72:707-714, 2010. (c) 2010 Wiley-Liss, Inc.
