People performing actions together have a natural tendency to synchronize their behavior. Consistently, people doing a task together build internal representations not only of their actions and goals, but also of the other people performing the task. However, little is known about which are the behavioral mechanisms and the psychological factors affecting the subjective sensation of synchrony, or "connecting" with someone else. In this work, we sought to find which factors induce the subjective sensation of synchrony, combining motion capture data and psychological measures. Our results show that the subjective sensation of synchrony is affected by performance quality together with task category, and time. Psychological factors such as empathy and negative subjective affects also correlate with the subjective sensation of synchrony. However, when people estimate synchrony as seen from a third person perspective, their psychological factors do not affect the accuracy of the estimation. We suggest that to feel this sensation it is necessary to, first, have a good joint performance and, second, to assume the existence of an attention monitoring mechanism that reports that the attention of both participants (self and other) is focused on the task.
共同执行动作的人有一种自然的倾向，会使他们的行为同步。同样地，一起完成一项任务的人不仅会构建关于自己的行为和目标的内部表征，还会构建关于执行该任务的其他人的内部表征。然而，对于影响同步的主观感受，即与他人“建立联系”的行为机制和心理因素，我们却知之甚少。在这项研究中，我们试图通过结合动作捕捉数据和心理测量方法，找出哪些因素会引发同步的主观感受。我们的研究结果表明，同步的主观感受受到表现质量、任务类别以及时间的影响。诸如同理心和负面主观情绪等心理因素也与同步的主观感受相关。然而，当人们从第三人称视角估计同步情况时，他们的心理因素并不会影响估计的准确性。我们认为，要产生这种感受，首先要有良好的协同表现，其次要假定存在一种注意力监测机制，该机制会报告双方参与者（自我和他人）的注意力都集中在任务上。
