This experimental study investigated approach behavior toward opposite-sex others of similar versus dissimilar physical attractiveness. Furthermore, it tested the moderating effects of sex. Single participants interacted with confederates of high and low attractiveness. Observers rated their behavior in terms of relational investment (i.e., behavioral efforts related to the improvement of interaction fluency, communication of positive interpersonal affect, and positive self-presentation). As expected, men displayed more relational investment behavior if their own physical attractiveness was similar to that of the confederate. For women, no effects of attractiveness similarity on relational investment behavior were found. Results are discussed in the light of positive assortative mating, preferences for physically attractive mates, and sex differences in attraction-related interpersonal behaviors.
这项实验研究调查了对具有相似或不同身体吸引力的异性的接近行为。此外，它还测试了性别的调节作用。单身参与者与具有高吸引力和低吸引力的同伴进行互动。观察者根据关系投入（即与提高互动流畅性、传递积极人际情感和积极自我展示相关的行为努力）对他们的行为进行评分。正如预期的那样，如果男性自身的身体吸引力与同伴相似，他们会表现出更多的关系投入行为。对于女性，未发现吸引力相似性对关系投入行为有影响。根据积极的选型交配、对身体有吸引力的配偶的偏好以及与吸引力相关的人际行为中的性别差异对结果进行了讨论。
