令人惊讶的是，人们对黑猩猩的眼球运动知之甚少，尽管这些知识对比较认知研究有潜在的贡献。在这里，我们首次对黑猩猩的眼动追踪进行了检查。我们记录了黑猩猩在观看包含黑猩猩、人类或其他哺乳动物全身图像的自然主义图片时的眼球运动;并将结果与人类的结果进行了比较。我们发现这两个物种的视觉模式惊人的相似。无论是黑猩猩还是人类，看动物形象的时间都比看背景的时间长，看面部的时间也比看身体其他部位的时间长。当两个物种看到黑猩猩和人类的照片时，他们第一眼就发现了面部区域。然而，黑猩猩的眼球运动也表现出与人类明显的差异;前者比后者更快更广泛地转移注视位置。此外，黑猩猩注视面部区域的平均持续时间比人类短。总的来说，我们的研究结果清楚地表明了两种灵长类动物共同的眼动策略，并提出了几个显着的差异，表现在观察的场景和身体形态的图片。
Surprisingly little is known about the eye movements of chimpanzees, despite the potential contribution of such knowledge to comparative cognition studies. Here, we present the first examination of eye tracking in chimpanzees. We recorded the eye movements of chimpanzees as they viewed naturalistic pictures containing a full-body image of a chimpanzee, a human or another mammal; results were compared with those from humans. We found a striking similarity in viewing patterns between the two species. Both chimpanzees and humans looked at the animal figures for longer than at the background and at the face region for longer than at other parts of the body. The face region was detected at first sight by both species when they were shown pictures of chimpanzees and of humans. However, the eye movements of chimpanzees also exhibited distinct differences from those of humans; the former shifted the fixation location more quickly and more broadly than the latter. In addition, the average duration of fixation on the face region was shorter in chimpanzees than in humans. Overall, our results clearly demonstrate the eye-movement strategies common to the two primate species and also suggest several notable differences manifested during the observation of pictures of scenes and body forms.
