The mechanisms of romantic bonding in humans are largely unknown. Recent research suggests that physiological synchrony between partners is associated with bonding. This study combines an experimental approach with a naturalistic dating setup to test whether the individual differences in social and nonsocial synchrony are interdependent, and linked to romantic attractiveness. In a preregistered online experiment with 144 participants, we discover that inducing physiological synchrony between an actor and an actress determines their attractiveness ratings by participants, indicating that synchrony can increase perceived attraction. In a lab-based naturalistic speed-dating experiment, we quantify in 48 participants the individual tendency for social physiological synchrony, nonsocial sensorimotor synchrony, and romantic attractiveness. We discover that the individual propensity to synchronize in social and nonsocial tasks is correlated. Some individuals synchronize better regardless of partners or tasks, and such Super Synchronizers are rated as more attractive. Altogether, this demonstrates that humans prefer romantic partners who can synchronize.
人类浪漫关系形成的机制在很大程度上尚不明确。近期研究表明，伴侣之间的生理同步与关系形成有关。本研究将实验方法与自然主义约会设置相结合，以测试社交同步和非社交同步中的个体差异是否相互依存，并与浪漫吸引力相关联。在一项有144名参与者的预先注册的在线实验中，我们发现诱导一名男演员和一名女演员之间的生理同步会决定参与者对他们的吸引力评分，这表明同步可以增加感知到的吸引力。在一项基于实验室的自然主义速配实验中，我们对48名参与者的社交生理同步、非社交感觉运动同步和浪漫吸引力的个体倾向进行了量化。我们发现，个体在社交和非社交任务中同步的倾向是相关的。有些人无论伴侣或任务如何都能更好地同步，而这些超级同步者被认为更具吸引力。总之，这表明人类更喜欢能够同步的浪漫伴侣。
