Though the left cheek appears more emotive, perceptions of attractiveness vary with gender. For the first time, this study assessed the relationship between perceptions of emotion (happiness) and attractiveness in naturalistic photographic portraits. One hundred ninety-two participants (63 male; 129 female) viewed pairs of left and right cheek poses, and made a forced-choice decision indicating which image appeared (a) more emotive and (b) more attractive (order counterbalanced). Half the images were mirror-reversed to control for perceptual biases. Results indicated a striking gender difference: for males, the left cheek appears both more emotive and more attractive; for females, preferences are subject to stronger perceptual influences, with the right cheek bias for emotion and attractiveness reversing to a left cheek bias when images are mirror-reversed. These findings suggest that if you want to show the world your "best side", men should lead with the left but for women, the right cheek is right.
尽管左脸颊看起来更具表情，但吸引力的感知因人而异。本研究首次评估了在自然摄影肖像中，对情绪（快乐）和吸引力的感知之间的关系。192 名参与者（63 名男性；129 名女性）观看了左右脸颊姿势的成对图像，并进行了强制选择决策，表明哪个图像看起来（a）更有表情，（b）更有吸引力（顺序平衡）。一半的图像被镜像反转以控制感知偏差。结果表明存在显著的性别差异：对于男性，左脸颊看起来既更有表情，也更有吸引力；对于女性，偏好受到更强的感知影响，当图像被镜像反转时，情绪和吸引力的右脸颊偏向反转到左脸颊偏向。这些发现表明，如果你想向世界展示你的“最佳一面”，男性应该用左脸，但对于女性来说，右脸是正确的。
