Women tend to have a smaller chin, fuller lips, and rounder eyes than men, due in part to the effects of estrogen. These features associated with facial femininity have been found to be positively associated with fertility. Although young men in their 20s typically judge facial femininity as more attractive than facial masculinity, at all ages, men with higher sexual desire and testosterone levels tend to show a marked preference for feminine faces. In the current study, we extend this research using a large cross-national sample to test the hypothesis that facial femininity preferences will be stronger among younger men than among older men. We also tested whether these preferences are influenced by self-reported sexual openness, national health indices, and gross national income.
We quantified attractiveness judgments (i.e., preferences) among 2,125 heterosexual men (aged 17-73 years) for female faces that were manipulated to appear more or less feminine using a computer graphics program.
Facial femininity preferences decreased with age, being highest among men in their 30s and lowest among men in their 70s. This pattern was independent of men's sexual openness and cross-national variation in health and socioeconomic development.
Our study shows that men's preferences for facial femininity are age dependent. At the proximate level, differences in preferences could reflect age-related declines in testosterone levels. These age-related declines in preferences could benefit older men, who are less able to invest in mating effort, and thus may opt out of competition with younger men for mates with potentially higher fertility.
女性往往比男性有更小的下巴、更丰满的嘴唇和更圆润的眼睛,部分原因是雌激素的作用。已发现这些与面部女性气质相关的特征与生育能力呈正相关。尽管20多岁的年轻男性通常认为面部女性气质比面部男性气质更具吸引力,但在所有年龄段,性欲和睾酮水平较高的男性往往明显偏好女性化的面孔。在本研究中,我们使用一个大型跨国样本扩展了这项研究,以检验以下假设:年轻男性对面部女性气质的偏好将比年长男性更强。我们还测试了这些偏好是否受到自我报告的性开放程度、国家健康指数和国民总收入的影响。
我们使用计算机图形程序对2125名异性恋男性(年龄在17 - 73岁之间)对经过处理显得或多或少具有女性气质的女性面孔的吸引力判断(即偏好)进行了量化。
对面部女性气质的偏好随年龄下降,在30多岁的男性中最高,在70多岁的男性中最低。这种模式与男性的性开放程度以及健康和社会经济发展的跨国差异无关。
我们的研究表明,男性对面部女性气质的偏好取决于年龄。在直接层面上,偏好的差异可能反映了睾酮水平与年龄相关的下降。这些与年龄相关的偏好下降可能对年长男性有利,因为他们在交配努力方面的投入能力较低,因此可能选择退出与年轻男性争夺具有潜在更高生育能力的配偶的竞争。
