面孔在视觉上对人类和非人类灵长类动物都有吸引力。人类新生儿被认为在出生时对面孔有一个广泛的模板，并且更喜欢面孔类刺激而不是非面孔类刺激。为了更好地比较人脸处理的发育轨迹，我们利用真实的人脸照片研究了婴儿恒河猴对人脸类刺激的偏好。我们向15-25天的猕猴婴儿展示了正常和线性排列的人脸、猕猴脸和抽象脸，并使用眼动追踪技术测量了婴儿注视每张脸的持续时间、注视次数和延迟时间。对于抽象面孔和猴子面孔，人们总体上更倾向于正常而不是线性的面部排列，而不是人脸。此外，猕猴幼崽看猴子脸的次数比看抽象面孔或人脸的次数要少。这些结果表明，物种和面部结构影响了猕猴幼崽的面部加工，我们讨论了这些发现的潜在解释。此外，需要进行仔细的对照研究，以确定猕猴婴儿的面部模板是否可以被认为与人类婴儿的面部模板一样宽。版权所有©2013 John Wiley & Sons， Ltd
Faces are visually attractive to both human and nonhuman primates. Human neonates are thought to have a broad template for faces at birth and prefer face‐like to non‐face‐like stimuli. To better compare developmental trajectories of face processing phylogenetically, here, we investigated preferences for face‐like stimuli in infant rhesus macaques using photographs of real faces. We presented infant macaques aged 15–25 days with human, macaque and abstract faces with both normal and linear arrangements of facial features and measured infants' gaze durations, number of fixations and latency to look to each face using eye‐tracking technology. There was an overall preference for normal over linear facial arrangements for abstract and monkey faces but not human faces. Moreover, infant macaques looked less at monkey faces than at abstract or human faces. These results suggest that species and facial configurations affect face processing in infant macaques, and we discuss potential explanations for these findings. Further, carefully controlled studies are required to ascertain whether infant macaques' face template can be considered as broad as human infants' face template.
