Studies of facial asymmetry have revealed that the left and the right sides of the face differ in emotional attributes. This paper reviews many of these distinctions to determine how these asymmetries influence portrait paintings. It does so by relating research involving emotional expression to aesthetic pleasantness in portraits. For example, facial expressions are often asymmetrical-the left side of the face is more emotionally expressive and more often connotes negative emotions than the right side. Interestingly, artists tend to expose more of their poser's left cheek than their right. This is significant, in that artists also portray more females than males with their left cheek exposed. Reasons for these psychological findings lead to explanations for the aesthetic leftward bias in portraiture.
对面部不对称的研究表明，人脸的左右两侧在情感属性上存在差异。本文综述了这些差异中的许多差异，以确定这些不对称性如何影响肖像画。它通过将涉及情感表达的研究与肖像画中的审美愉悦联系起来，从而做到了这一点。例如，面部表情通常是不对称的——与右侧相比，左侧的面部表情更具情感表现力，并且更常表示负面情绪。有趣的是，艺术家往往会暴露出更多模特的左脸颊，而不是右脸颊。这很重要，因为艺术家也更喜欢用左脸颊来描绘女性，而不是男性。这些心理学发现的原因导致了对肖像画中审美左偏的解释。
