灵长类动物发展了通过面部识别并个性化其相似特征的能力。尽管在猴子身上进行了大量的电生理学研究[1-3]，但人们对猴子使用的面部处理策略知之甚少。相比之下，人类的脸部感知一直是许多研究的主题[4-6]，为特定的脸部加工提供了证据，这些加工是随着知觉专长的进化[7]。重要的是，人类整体地处理人脸，这里定义为将人脸作为整体处理，而不是独立特征的集合(基于部分的处理)[8]。问题仍然是，人类和猴子在多大程度上分享了这些面部处理机制。通过对猴子和人类行为实验使用相同的实验设计和刺激，我们发现人脸加工受到观察到的人脸刺激(人与猕猴脸)的物种从属关系的影响。此外，选择性地减少整体和部分信息的刺激操作系统地改变了人类和猕猴观察者的眼睛扫描模式。这些结果证明了人类和猴子的面孔感知的相似性质，并确定了专家面孔处理策略与新手面孔处理策略的效果。因此，这些发现直接促成了行为科学和神经科学中关于灵长类动物如何感知面孔的核心讨论之一。
Primates developed the ability to recognize and Individuate their conspecifics by the face. Despite numerous electrophysiological studies in monkeys [1-3], little is known about the face-processing strategies that monkeys employ. In contrast, face perception In humans has been the subject of many studies [4-6] providing evidence for specific face processing that evolves with perceptual expertise [7]. Importantly, humans process faces holistically, here defined as the processing of faces as wholes, rather than as collections of Independent features (part-based processing) [8]. The question remains to what extent humans and monkeys share these face-processing mechanisms. By using the same experimental design and stimuli for both monkey and human behavioral experiments, we show that face processing Is influenced by the species affiliation of the observed face stimulus (human versus macaque face). Furthermore, stimulus manipulations that selectively reduced holistic and part-based information systematically altered eye-scanning patterns for human and macaque observers similarly. These results demonstrate the similar nature of face perception in humans and monkeys and pin down effects of expert face-processing versus novice face-processing strategies. These findings therefore directly contribute to one of the central discussions in the behavioral and neurosciences about how faces are perceived In primates.
