先前的研究已经发现，在男性面孔中，男性气质和对称性之间存在着积极的关系，这是两个公认的伴侣质量的标志。我们重新研究了这种关系，使用一个明确的措施，面部波动的不对称性，以及其他措施的不对称性，和面部男性气质/女性气质的措施。我们还使用了这些特征对面孔的评级。此外，我们还研究了面部性别差异与身体不对称之间的关系。我们没有发现面部男性气质和我们对男性不对称性的任何测量或对称性评级之间存在显着相关性。面部女性化并不总是与女性的面部对称性相关，但与身体对称性相关。因此，对于女性，而不是男性，面部女性气质和身体对称性可能反映了配偶质量的相似方面。我们还研究了特质评级和测量之间的关系。我们的研究结果提供了验证，我们的能力来衡量方面的不对称，被认为是对称的，以及方面的性别二态性，被认为是女性的女性和男性的男性。
Previous studies have found both support and lack of support for a positive relationship between masculinity and symmetry, two putative signs of mate quality, in male faces. We re-examined this relationship using an explicit measure of facial fluctuating asymmetry, as well as other measures of asymmetry, and measures of facial masculinity/ femininity. We also used ratings of these traits for faces. Further, we examined the relationship between facial sexual dimorphism and body asymmetry. We found no significant correlations between facial masculinity and any of our measures of asymmetry or ratings of symmetry in males. Facial femininity was not consistently associated with facial symmetry in females, but was associated with body symmetry. Therefore, for females, but not males, facial femininity and body symmetry may reflect similar aspects of mate quality. We also examined the relationships between trait ratings and measurements. Our results provide validation of our ability to measure aspects of asymmetry that are perceived to be symmetrical, and aspects of sexual dimorphism that are perceived as feminine in females and masculine in males.
