人脸的性别识别是社会认知的基础。尽管如此，表明面部性别的感知线索及其发展背后的机制仍然知之甚少。之前，我们的小组描述了健康男性和女性青少年（12-18岁）面部的客观年龄和性别相关差异，这些差异来自于青少年头部的磁共振图像（mri）。在这项研究中，我们将这些青少年的面孔呈现给60名女性评分者，以确定哪些面部特征最可靠地预测了主观性别认同。识别准确性与特定的mri衍生面部特征（如更宽的额头、下巴、下巴和鼻子）高度相关。最可靠地提示男性身份的面部特征与血浆睾酮水平相关（高于或超过年龄）。因此，脸型上明显的性别差异与特定的面部特征有关，这些特征的出现可能在一定程度上是由睾丸激素驱动的。(C) 2011爱思唯尔公司版权所有。
Sex identification of a face is essential for social cognition. Still, perceptual cues indicating the sex of a face, and mechanisms underlying their development, remain poorly understood. Previously, our group described objective age- and sex-related differences in faces of healthy male and female adolescents (12-18 years of age), as derived from magnetic resonance images (MRIs) of the adolescents' heads. In this study, we presented these adolescent faces to 60 female raters to determine which facial features most reliably predicted subjective sex identification. Identification accuracy correlated highly with specific MRI-derived facial features (e.g. broader forehead, chin, jaw, and nose). Facial features that most reliably cued male identity were associated with plasma levels of testosterone (above and beyond age). Perceptible sex differences in face shape are thus associated with specific facial features whose emergence may be, in part, driven by testosterone. (C) 2011 Elsevier Inc. All rights reserved.
