猕猴社会中个体的成功整合表明，猴子使用快速有效的感知机制来区分同种。人类和类人猿主要使用整体和结构性的，但也基于特征的面部识别处理。这些过程对猴子面部识别的相对贡献尚不清楚。我们测量了三只猴子的面部识别进行视觉配对比较任务。猴子和人类的面部（1）轴向旋转，（2）倒置，（3）高通滤波，（4）低通滤波，以隔离不同的面部处理策略。对于每种类型的刺激操作，观察眼睛、嘴巴和其他面部特征所花费的时间在猴子和人类面部之间进行了比较。对于所有的猴子，面部识别，表示为新奇的偏好，是完整的猴子的脸，轴向旋转或空间过滤，并支持在一般情况下优先看眼睛，但受损的倒置的脸在两个三只猴子。轴向旋转，直立的人脸与全范围的空间频率也被认可，然而，探索每个面部特征所花费的时间分布与猴子的脸相比有显着不同。没有新奇的偏好，因此没有推断的识别，观察倒置或低通滤波的人脸。高通滤波的人脸被识别，然而，面部特征上的寻找模式偏离了猴子面部观察到的模式。总之，这些结果表明，在识别成功和猴子识别人类与同种使用的感知策略有很大的差异。猴子使用二阶图形和基于特征的处理来识别同种的面孔，但它们主要使用基于特征的策略来识别人类面孔。
Successful integration of individuals in macaque societies suggests that monkeys use fast and efficient perceptual mechanisms to discriminate between conspecifics. Humans and great apes use primarily holistic and configural, but also feature-based, processing for face recognition. The relative contribution of these processes to face recognition in monkeys is not known. We measured face recognition in three monkeys performing a visual paired comparison task. Monkey and humans faces were (1) axially rotated, (2) inverted, (3) high-pass filtered, and (4) low-pass filtered to isolate different face processing strategies. The amount of time spent looking at the eyes, mouth, and other facial features was compared across monkey and human faces for each type of stimulus manipulation. For all monkeys, face recognition, expressed as novelty preference, was intact for monkey faces that were axially rotated or spatially filtered and was supported in general by preferential looking at the eyes, but was impaired for inverted faces in two of the three monkeys. Axially rotated, upright human faces with a full range of spatial frequencies were also recognized, however, the distribution of time spent exploring each facial feature was significantly different compared to monkey faces. No novelty preference, and hence no inferred recognition, was observed for inverted or low-pass filtered human faces. High-pass filtered human faces were recognized, however, the looking pattern on facial features deviated from the pattern observed for monkey faces. Taken together these results indicate large differences in recognition success and in perceptual strategies used by monkeys to recognize humans versus conspecifics. Monkeys use both second-order configural and feature-based processing to recognize the faces of conspecifics, but they use primarily feature-based strategies to recognize human faces.
