This study examined both self-rated and objectively measured attractiveness in relation to sexual behaviors and attitudes in an undergraduate sample (N=456). About a quarter of the variance in self-ratings of attractiveness was predicted from combining standard objective measures of attractiveness, including face photo ratings, body mass index, and chest-to-waist ratio for men, and face photo ratings, body mass index, and waist-to-hip ratio for women. Correlations were investigated among self-rated attractiveness, measured attractiveness, the residual component of self-rated attractiveness (controlling for measured attractiveness), and a number of sexual and related variables. Measured attractiveness correlated moderately with sexual behaviors but not with sociosexuality or sexual moral attitudes, indicating that higher levels of observable attractiveness may serve to increase opportunities for sex with multiple desirable partners without affecting interests in or moral acceptance of casual sex. Self-rated attractiveness correlated positively with sexual behaviors and with sociosexuality, but the correlation with sociosexuality was based entirely on residual factors beyond the objective measures of attractiveness. Other predictors of sexual behavior were discussed in terms of their variable roles in affecting interest in, opportunities for, and social costs of promiscuous sexual activity.
本研究在一个本科样本（N = 456）中，考察了与性行为及态度相关的自评吸引力和客观测量的吸引力。将包括面部照片评分、体重指数以及男性的胸腰比、女性的面部照片评分、体重指数和腰臀比等标准客观吸引力测量指标相结合，可以预测约四分之一的吸引力自评差异。研究调查了自评吸引力、测量的吸引力、自评吸引力的残差成分（控制测量的吸引力）以及一些性和相关变量之间的相关性。测量的吸引力与性行为呈中度相关，但与社会性取向或性道德态度无关，这表明较高水平的可观察到的吸引力可能有助于增加与多个理想伴侣发生性行为的机会，而不会影响对随意性行为的兴趣或道德接受度。自评吸引力与性行为和社会性取向呈正相关，但与社会性取向的相关性完全基于吸引力客观测量指标之外的残差因素。还讨论了性行为的其他预测因素在影响滥交性行为的兴趣、机会和社会成本方面的不同作用。
