有大量证据表明野生动物的群体特定行为被认为是通过社会传播的。然而，关于猴子通过观察同类进行学习的程度，对猴子的实验研究报告了相互矛盾的证据。在这项研究中，我们测试了使用预先录制的视频演示来研究恒河猴同种社会学习的可行性。通过训练，猴子逐渐学会了根据演示视频做出正确反应，然而，后续实验表明，这并不是因为向演示猴子学习。在水平反转视频的泛化测试中，猴子继续对与每个视频相关的位置做出反应，而不是匹配镜像视频中显示的新选择位置。当任务更改为与位置无关时，猴子只能通过选择演示者在视频中选择的相同图像才能正确选择，观察猴子在 12,000 次训练试验中没有超过机会。由于猴子很容易学会遵循显示器上呈现的非社交视觉线索来指导图像选择，因此它们无法向演示者学习，这表明从视频进行社交学习的能力存在很大限制。此外，这些发现鼓励人们更深入地思考猴子在电脑屏幕上看到视频刺激时的感知。
There is substantial evidence of group-specific behaviors in wild animals that are thought to be socially transmitted. Yet experimental studies with monkeys have reported conflicting evidence on the extent to which monkeys learn by observing their conspecifics. In this study, we tested the feasibility of using pre-recorded video demonstrations to investigate social learning from conspecifics in rhesus monkeys. With training, monkeys gradually learned to respond correctly following videos of a demonstrator, however, follow-up experiments revealed that this was not due to learning from the demonstrator monkey. In generalization tests with videos that were horizontally reversed, monkeys continued responding to the location they had associated with each video, rather than matching the new choice location shown in the mirrored video. When the task was changed to make location irrelevant, such that monkeys could choose correctly only by selecting the same image selected by the demonstrator in the video, observer monkeys did not exceed chance in 12,000 training trials. Because monkeys readily learn to follow nonsocial visual cues presented on a monitor to guide image choice, their inability to learn from a demonstrator here indicates substantial limitations in the capacity for social learning from videos. Furthermore, these findings encourage deeper consideration of what monkeys perceive when presented with video stimuli on computer screens.
