PNAS:现代约会情境下的伸展性与成功
美国加州大学伯克利分校一项研究提出，伸展的身体姿势可能让人们在快速约会情况下更具浪漫吸引力。近几十年来，科研人员在识别长期关系中的与浪漫吸引力有关的非言语行为方面取得了进展。然而，人们对于在最初的浪漫相遇中增加吸引力的非言语展示相对了解较少。Tanya Vacharkulksemsuk及其同事检验了开放的、扩张的姿势，诸如伸展的肢体或伸长的躯干，是否能增加一个人在快速和网上约会情况下对可能的浪漫伙伴的吸引力。对异性夫妇的144次快速约会的视频的分析揭示出，伸展的身体姿势让获得一个高的吸引力评分和让约会伙伴同意进行第二次的传统约会的可能性几乎加倍。类似地，对网上约会档案的将近3000次响应的分析表明，当人们展示开放的、伸展的姿势而不是封闭的、收缩的姿势的时候，人们获得了更多的“同意”的回应。伸展的姿势吸引可能的伴侣的一个方式是传达优势地位与开放性——这些特征与获取资源以及愿意分享这些资源有关。这组作者说，这些发现提示，个体可以利用微妙但是强有力的非言语展示，从而在现代的快速约会情况下给人带来一种积极的第一印象并约会成功。

Dominant, open nonverbal displays are attractive at zero-acquaintance
原文摘要：
Across two field studies of romantic attraction, we demonstrate that postural expansiveness makes humans more romantically appealing. In a field study (n = 144 speed-dates), we coded nonverbal behaviors associated with liking, love, and dominance. Postural expansiveness—expanding the body in physical spAce—was most predictive of attraction, with each one-unit increase in coded behavior from the video recordings nearly doubling a person’s odds of getting a “yes” response from one’s speed-dating partner. In a subsequent field experiment (n = 3,000), we tested the causality of postural expansion (vs. contraction) on attraction using a popular global Positioning System-based online-dating application. Mate-seekers rapidly flipped through photographs of potential sexual/date partners, selecting those they desired to meet for a date. Mate-seekers were significantly more likely to select partners displaying an expansive (vs. contractive) nonverbal posture. Mediation analyses demonstrate one plausible mechanism through which expansiveness is appealing: Expansiveness makes the dating candidate appear more dominant. In a dating world in which success sometimes is determined by a split-second decision rendered after a brief interaction or exposure to a static photograph, single persons have very little time to make a good impression. Our research suggests that a nonverbal dominance display increases a person’s chances of being selected as a potential mate.
