Previous studies demonstrate that people with different personality traits have different-looking faces. We investigated whether personality and health information are differently signalled by the two hemifaces. Using composite images created from women with high and low scores on health and personality dimensions, we investigated discrimination accuracy with original and mirrored hemifaces. By comparing discrimination accuracy for particular types of hemiface, we address issues regarding both the location of information signals and how these signals are conveyed. From the hemiface stimuli, participants could accurately identify three of the Big Five traits, along with health. We found differences in which hemiface could be more accurately identified, depending on the expressed trait. Emotional stability and health were more accurately discriminated from the right hemiface, while extraversion showed higher accuracy from the left hemiface. We found evidence for differences between hemifaces related to both directional asymmetries and to other information content. Finally, our results also address ongoing debate about which side of the face is more attractive, as we found attractiveness differences between hemifaces depended upon the personality trait most clearly expressed.
以往的研究表明，具有不同性格特征的人面部外观也不同。我们研究了人格和健康信息在左右半脸的信号传递是否存在差异。利用在健康和人格维度上得分高和低的女性所创建的合成图像，我们研究了原始半脸和镜像半脸的辨别准确率。通过比较特定类型半脸的辨别准确率，我们探讨了信息信号的位置以及这些信号如何传递的问题。从半脸刺激中，参与者能够准确识别出“大五”人格特质中的三项，以及健康状况。我们发现，根据所表达的特质不同，左右半脸中哪一个能被更准确识别存在差异。从右半脸能更准确地辨别出情绪稳定性和健康状况，而从左半脸辨别外向性的准确率更高。我们发现了半脸之间与方向不对称性以及其他信息内容相关的差异证据。最后，我们的研究结果也回应了关于脸的哪一侧更具吸引力的持续争论，因为我们发现半脸之间的吸引力差异取决于最明显表达的人格特质。
