The influences of sex and lateralized visual hemispace bias in the judgment of the emotional valence of faces during a free viewing condition are evaluated. 73 subjects (aged 18 to 52 yr.) viewed videotaped facial expressions of emotion in normal and mirror-reversed orientation and classified each face as a positive, negative, or neutral expression. There was a significant interaction between the sex of the rater and the orientation of the face that influenced the proportion of correct classifications. Male and female perceivers did not differ in the accuracy of their affect judgments for faces viewed in normal orientation, whereas reversal of the orientation of the faces resulted in a significant enhancement of accuracy judgments for the males but not the females. The results suggest greater cerebral lateralization of perceptual processes in males.
评估了在自由观看条件下，性别和视觉半空间侧化偏向对面部情绪效价判断的影响。73名受试者（年龄在18至52岁之间）观看了正常和镜像反转方向的面部情绪录像，并将每张脸分类为积极、消极或中性表情。评分者的性别与面部方向之间存在显著的交互作用，这影响了正确分类的比例。对于以正常方向观看的面部，男性和女性感知者在情感判断的准确性上没有差异，而面部方向的反转导致男性的准确性判断显著提高，女性则不然。结果表明男性在感知过程中大脑侧化程度更高。
