女性通常比男性更关注社会信息；然而，关于这些性别差异的早期发展，人们知之甚少。通过眼球跟踪，在四个项目的图像阵列中测量了2个月大婴儿(N=6101；44名女性)对面孔的社会定向。与物体相比，婴儿更有可能检测到人脸，这表明人脸检测系统是有效的。出乎意料的是，男性看人脸的时间比女性长，而且只有男性看人脸的速度和时间比物体更快、更长。相比之下，与动物的脸和物体相比，女性看人的脸更少，显得对社会不感兴趣。值得注意的是，这是第一个关于男性在任何年龄都具有面部检测优势的报告。这些发现表明，婴儿早期社会发展处于一个独特的阶段。
Females generally attend more to social information than males; however, little is known about the early development of these sex differences. With eye tracking, 2‐month olds’ (N= 101; 44 females) social orienting to faces was measured within four‐item image arrays. Infants were more likely to detect human faces compared to objects, suggesting a functional face detection system. Unexpectedly, males looked longer at human faces than females, and only males looked faster and longer at human faces compared to objects. Females, in contrast, looked less at human faces relative to animal faces and objects, appearing socially disinterested. Notably, this is the first report of a male face detection advantage at any age. These findings suggest a unique stage in early infant social development.
