我们调查了是否有吸引力的面部特征的平均和对称信号的健康，检查信号的两个方面：这些特征是否被认为是健康的，以及它们是否提供准确的健康信息。在研究1中，我们使用变形技术来改变个体面部的平均度和对称性。这两个特征的增加增加了感知健康，感知健康与额定的独特性（平均值的匡威测量）呈负相关，与额定的图像对称性呈正相关。在研究2中，我们在一个基于详细医疗记录的健康评分样本中，研究了这些特征是否标志着真实的以及感知的健康。感知健康与独特性和不对称性呈负相关，复制研究1。17岁青少年的面部独特性评级与男性儿童健康状况不佳以及女性当前和青少年健康状况不佳有关，尽管最后一种关联仅具有轻微的显著性。17岁青少年的面部不对称与实际健康状况无关。我们讨论了这些结果的影响，一个很好的基因帐户的面部偏好。(C)2001 Elsevier Science Inc.

We investigated whether the attractive facial traits of averageness and symmetry signal health, examining two aspects of signalling: whether these traits are perceived as healthy, and whether they provide accurate health information. In Study 1, we used morphing techniques to alter the averageness and symmetry of individual faces. Increases in both traits increased perceived health, and perceived health correlated negatively with rated distinctiveness (a converse measure of averageness) and positively with rated symmetry of the images. In Study 2, we examined whether these traits signal real, as well as perceived, health, in a sample of individuals for whom health scores, based on detailed medical records, were available. Perceived health correlated negatively with distinctiveness and asymmetry, replicating Study 1. Facial distinctiveness ratings of 17-year-olds were associated with poor childhood health in males, and poor current and adolescent health in females, although the last association was only marginally significant. Facial asymmetry of 17-year-olds was not associated with actual health. We discuss the implications of these results for a good genes account of facial preferences. (C) 2001 Elsevier Science Inc.
