对于灵长类动物来说，面部是显着的刺激物，它们主要依靠视觉线索来识别同类和维持社会关系。虽然之前的研究表明黑猩猩和人类有类似的面部辨别过程，但来自猴子的数据尚不清楚。因此，三项研究利用面部反转效应、断裂面部任务和个体识别任务检查了恒河猴的面部处理。与黑猩猩和人类不同，猴子表现出普遍的面部倒置效应，无论受试者对这些类别的专业知识如何，与倒置面部（同种人，人类和黑猩猩的面部）相比，直立面部的表现明显更好。骨折面会改变一阶和二阶配置操作，而之前对黑猩猩的研究表明二阶配置操作存在选择性缺陷。最后，当需要区分同种人的面孔时，即匹配同一同种人的两张不同照片，猴子表现出较差的辨别力和重复训练。这些结果支持恒河猴和类人猿之间在结构线索的重要性及其区分同种面孔的能力方面存在进化差异，表明恒河猴缺乏面部专业知识。
Faces are salient stimuli for primates that rely predominantly on visual cues for recognizing conspecifics and maintaining social relationships. While previous studies have shown similar face discrimination processes in chimpanzees and humans, data from monkeys are unclear. Therefore, three studies examined face processing in rhesus monkeys using the face inversion effect, a fractured face task, and an individual recognition task. Unlike chimpanzees and humans, the monkeys showed a general face inversion effect reflected by significantly better performance on upright compared to inverted faces (conspecifics, human and chimpanzees faces) regardless of the subjects' expertise with those categories. Fracturing faces alters first- and second-order configural manipulations whereas previous studies in chimpanzees showed selective deficits for second-order configural manipulations. Finally, when required to individuate conspecific's faces, i.e., matching two different photographs of the same conspecific, monkeys showed poor discrimination and repeated training. These results support evolutionary differences between rhesus monkeys and Hominoids in the importance of configural cues and their ability to individuate conspecifics' faces, suggesting a lack of face expertise in rhesus monkeys.
