Humans are social animals whose well-being is shaped by the ability to attract and connect with one another, often through brief interactions. In addition to physical features, a choreography of movements, physical reactions and subtle expressions may help promote attraction. Here, we measured the physiological dynamics between pairs of participants during real-life dating interactions outside the laboratory. Participants wore eye-tracking glasses with embedded cameras and devices to measure physiological signals including heart rate and skin conductance. We found that overt signals such as smiles, laughter, eye gaze or the mimicry of those signals were not significantly associated with attraction. Instead, attraction was predicted by synchrony in heart rate and skin conductance between partners, which are covert, unconscious and difficult to regulate. Our findings suggest that interacting partners' attraction increases and decreases as their subconscious arousal levels rise and fall in synchrony.
人类是社会性动物，其幸福感往往通过吸引他人并与之建立联系的能力塑造而成，这种联系通常通过短暂互动来实现。除了身体特征外，一系列的动作编排、身体反应和微妙表情可能有助于增进吸引力。在此，我们在实验室外的现实约会互动中测量了参与者两两之间的生理动态变化。参与者佩戴了嵌入摄像头和测量心率及皮肤电导率等生理信号设备的眼动追踪眼镜。我们发现，诸如微笑、大笑、目光接触或对这些信号的模仿等公开信号与吸引力并无显著关联。相反，伴侣之间心率和皮肤电导率的同步性才是预测吸引力的因素，这些都是隐蔽的、无意识的且难以控制的。我们的研究结果表明，随着潜意识唤醒水平同步上升和下降，互动伴侣之间的吸引力也会相应增加或减少。
