在许多物种中，有越来越多的证据表明条件依赖型配偶选择，也就是说，个体的偏好随着选择者的条件而变化。例如，在人类中，面孔/身体更有吸引力的人，以及社会性取向较高的人，对异性面孔/身体中有吸引力的特征表现出更强的偏好。然而，以前的研究往往只使用相对简单、孤立的方法来衡量评分者的吸引力。在这里，我们使用3D身体扫描技术来检验评分者对异性身体中有吸引力的特征的偏好程度与评分者的体型、自我吸引力和社会性之间的关系。对于118名评分者和80个刺激模型，我们使用3D扫描仪提取与吸引力相关的身体尺寸(男性腰胸比[WCR]、女性腰臀比[WHR]和身高指数[VHI])，并测量评分者的自我吸引力和社会性。不出所料，WHR和VHI是女性身体吸引力的重要预测因子，而WCR和VHI是男性身体吸引力的重要预测因素。结果表明，男性评分员的社会性得分与女性身体对迷人(低)VHI和迷人(低)腰臀比的偏好程度呈正相关。此外，男性评分员的自我吸引力与女性身体对低VHI的偏好程度呈正相关。女性条件依赖偏好的唯一证据是，女性评分者有吸引力的VHI与男性身体对有吸引力的(低)WCR的偏好之间存在正相关。在评分者的体型和对迷人的异性身体特征的偏好的强度之间，没有观察到任何性别之间的其他显著关联。这些结果表明，在男性评分者中，评分者自我感觉到的吸引力和社会性是对迷人的异性体型偏好强度的重要预测因素，而评分者的身体特征--女性评分者的VHI除外--可能不能很好地预测两种性别的这些偏好。
There is accumulating evidence of condition-dependent mate choice in many species, that is, individual preferences varying in strength according to the condition of the chooser. In humans, for example, people with more attractive faces/bodies, and who are higher in sociosexuality, exhibit stronger preferences for attractive traits in opposite-sex faces/bodies. However, previous studies have tended to use only relatively simple, isolated measures of rater attractiveness. Here we use 3D body scanning technology to examine associations between strength of rater preferences for attractive traits in opposite-sex bodies, and raters' body shape, self-perceived attractiveness, and sociosexuality. For 118 raters and 80 stimuli models, we used a 3D scanner to extract body measurements associated with attractiveness (male waist-chest ratio [WCR], female waist-hip ratio [WHR], and volume-height index [VHI] in both sexes) and also measured rater self-perceived attractiveness and sociosexuality. As expected, WHR and VHI were important predictors of female body attractiveness, while WCR and VHI were important predictors of male body attractiveness. Results indicated that male rater sociosexuality scores were positively associated with strength of preference for attractive (low) VHI and attractive (low) WHR in female bodies. Moreover, male rater self-perceived attractiveness was positively associated with strength of preference for low VHI in female bodies. The only evidence of condition-dependent preferences in females was a positive association between attractive VHI in female raters and preferences for attractive (low) WCR in male bodies. No other significant associations were observed in either sex between aspects of rater body shape and strength of preferences for attractive opposite-sex body traits. These results suggest that among male raters, rater self-perceived attractiveness and sociosexuality are important predictors of preference strength for attractive opposite-sex body shapes, and that rater body traits -with the exception of VHI in female raters-may not be good predictors of these preferences in either sex.
