目前还没有达成一致意见，如何具体或一般的机制是新生儿的脸的喜好。我们解决这个问题，通过操纵的对比度极性的示意图和自然的脸相关的图像和评估新生儿的喜好。我们发现，无论是示意性的和自然的人脸图像，对比极性是很重要的。纽瑟芬并没有表现出对与直立脸相关的图像的偏好，除非它是由眼睛和嘴巴周围的较暗区域组成的。该结果与对具有头顶（自然）照明的面部的阴影区域和/或对眼睛接触的检测的灵敏度一致。
There is currently no agreement as to how specific or general are the mechanisms underlying newborns' face preferences. We address this issue by manipulating the contrast polarity of schematic and naturalistic face-related images and assessing the preferences of newborns. We find that for both schematic and naturalistic face images, the contrast polarity is important. Newborns did not show a preference for an upright face-related image unless it was composed of darker areas around the eyes and mouth. This result is consistent with either sensitivity to the shadowed areas of a face with overhead (natural) illumination and/or to the detection of eye contact.
