Facial asymmetry (facedness) of female and male college students was investigated. Comparisons of facedness were made between 45 female and 45 male Dartmouth undergraduates. Facedness was defined in terms of the relative sizes (in square centimetres) of the two hemifaces. Data were derived from measurements of two-dimensional frontal photographs of the subjects. Reliable differences in facedness were found between the two groups. The females on average were found to be right faced, the males left faced. This difference was interpreted in terms of the contralateral control (below the eyes) of the two sides of the face by the two hemispheres, and the known differences in cognitive processing by the two hemispheres (left hemisphere-verbal; right hemisphere-visuospatial) in females and males. The observed difference in facial asymmetry between the two sexes is attributed to differential muscular development of the two sides of the face as related to the factors just noted. Suggestions are made for further research on facedness, particularly in relation to different age groups.
对男女大学生的面部不对称（面部偏向）情况进行了调查。对45名达特茅斯学院的女本科生和45名男本科生的面部偏向进行了比较。面部偏向是根据两个半脸的相对大小（平方厘米）来定义的。数据来自对受试者二维正面照片的测量。发现两组之间在面部偏向上存在可靠的差异。平均而言，女性被发现面部偏右，男性面部偏左。这种差异是根据两个半球对脸两侧（眼睛以下）的对侧控制，以及已知的男女两性两个半球（左半球 - 语言；右半球 - 视觉空间）在认知加工上的差异来解释的。观察到的两性之间面部不对称差异归因于与上述因素相关的脸部两侧肌肉发育差异。针对面部偏向的进一步研究提出了建议，特别是与不同年龄组相关的研究。
