Facial symmetry has been proposed as a marker of developmental stability that may be important in human mate choice. Several studies have demonstrated positive relationships between facial symmetry and attractiveness. It was recently proposed that symmetry is not a primary cue to facial attractiveness, as symmetrical faces remain attractive even when presented as half faces (with no cues to symmetry). Facial sexual dimorphisms ('masculinity') have been suggested as a possible cue that may covary with symmetry in men following data on trait size/symmetry relationships in other species. Here, we use real and computer graphic male faces in order to demonstrate that (i) symmetric faces are more attractive, but not reliably more masculine than less symmetric faces and (ii) that symmetric faces possess characteristics that are attractive independent of symmetry, but that these characteristics remain at present undefined.
面部对称性已被提议作为发育稳定性的一个标志，这在人类配偶选择中可能很重要。几项研究已经证明了面部对称性与吸引力之间的正相关关系。最近有人提出，对称性不是面部吸引力的主要线索，因为即使对称脸以半脸呈现（没有对称性线索）时仍具有吸引力。根据其他物种性状大小/对称性关系的数据，面部性二态性（“男子气概”）被认为是一种可能与男性对称性相关的线索。在这里，我们使用真实的和计算机生成的男性面孔来证明：（i）对称脸更具吸引力，但并不比不对称脸更具明显的男子气概；（ii）对称脸具有独立于对称性之外的吸引人的特征，但目前这些特征尚未明确。
