In the present study we assessed the contribution of the two hemispheres to the attribution of gender of faces in male and female observers. Normal and chimeric faces were presented in their canonical orientation and upside-down in a tachistoscopic paradigm. Chimeric faces were composed of two halves (left and right) obtained from photos of individuals of the same sex or from individuals of different sexes. All faces were presented tachistoscopically with a central fixation, the two halves falling in the two visual fields of the observer, who was required to rapidly judge the sex of the face. A left half-face (right-hemispheric) bias for gender attribution with upright faces was observed both in male and female participants, as previously reported. Strikingly, however, the bias depended entirely on female-left/male-right chimeras, revealing a right-hemispheric advantage for the recognition of female faces. The results are discussed in the light of a behavioural bias during development (i.e., maternal cradling).

右半球女性脸的偏斜。

在本研究中,我们评估了两个半球对男性和女性观察者面部性别的贡献。正常和嵌合的脸部以规范的方向呈现,并且在倒立镜式下颠倒过来。嵌合的面孔由两半(左和右)组成,这些两半是从同性或不同性别的人的照片中获得的。所有的脸部都用中心视线镜检呈现,两个半部分落在观察者的两个视野中,观察者需要快速判断脸的性别。如先前报道,在男性和女性参与者中均观察到左半脸(右半球)的性别归因与直立面孔的偏见。令人惊讶的是,这种偏见完全取决于雌性左/雄性右嵌合体,揭示了右半球在识别女性面孔方面的优势。鉴于发育过程中的行为偏见(即产妇),对结果进行了讨论。
