有很多证据表明，人类和其他物种一样，在做出择偶决定时会受到社会信息的影响。目睹竞争对手对异性表现出兴趣，往往会导致两性的人类观察者随后将该人评为更具吸引力的潜在伴侣。然而，这是如何发生的还不清楚。我们调查这种效应是否是特定的个人见证或将推广到其他潜在的配偶与共享的特征，即人类是否表现出基于特质或只是基于个人的择偶复制。我们发现，虽然这种泛化确实发生在某些特征上，但它似乎取决于年龄，而且很明显，它不会发生在（内部）面部特征上。我们讨论了可能的解释年龄特异性和线索特异性的信息效益和人们如何参加不熟悉的面孔。
There is much evidence that humans, as other species, are affected by social information when making mate-choice decisions. Witnessing a rival show interest in a member of the opposite sex tends to lead human observers of both sexes to thereafter rate that person as more appealing as a potential mate. However, how this occurs is not well understood. We investigate whether this effect is specific to the individual witnessed or will generalize to other potential mates with shared characteristics-that is, whether humans exhibit trait-based or just individual-based mate-choice copying. We found that whereas this kind of generalization did occur with some traits, it appeared to depend on age, and conspicuously, it did not occur with (inner) facial traits. We discuss possible explanations for the age specificity and cue specificity in terms of informational benefits and how people attend to unfamiliar faces.
