Collective synchrony refers to the simultaneous occurrence of behavior, cognition, emotion, and/or physiology within teams of three or more persons. It has been suggested that collective synchrony may emanate from the copresence of team members, from their engagement in a shared task, and from coordination enacted in pursuit of a collective goal. In this paper, a regime-switching dynamic factor analytical approach is used to examine interindividual similarities in a particular behavioral measure (i.e., speed) in a collegiate soccer team. First, the analytical approach is presented didactically, including the state space modeling framework in general, followed by the regime-switching dynamic factor model in particular. Next, an empirical application of the approach is presented. Speed similarity (covariation in speed, operationalized in two ways: running cadence and distance covered) during competitive women’s soccer games is examined. A key methodological aspect of the approach is that the collective is the unit of analysis, and individuals vary about collective dynamics and their evolution. Reporting on the results of this study, we show how features of substantive interest, such as the magnitude and prevalence of behavioral similarity, can be parameterized, interpreted, and aggregated. Finally, we highlight several key findings, as well as opportunities for future research, in terms of methodological and substantive aims for advancing the study of collective synchrony.

集体同步是指在三人或三人以上的团队中同时发生行为、认知、情感和/或生理。有人提出，集体同步可能来自团队成员的共同存在、来自他们对共同任务的参与以及为追求集体目标而制定的协调。在本文中，使用一种制度转换动态因素分析方法来检查大学足球队中特定行为测量（即速度）的个体间相似性。首先，分析方法以教学方式呈现，包括一般的状态空间建模框架，特别是状态切换动态因子模型。接下来，介绍了该方法的经验应用。速度相似性（速度的协变，以两种方式操作：在竞争性女子足球比赛期间，跑步节奏和距离）进行了检查。该方法的一个关键方法论方面是集体是分析单位，个人对集体动态及其演变的看法各不相同。在报告本研究的结果时，我们展示了如何对具有实质性兴趣的特征（例如行为相似性的大小和普遍性）进行参数化、解释和汇总。最后，在推进集体同步研究的方法和实质性目标方面，我们强调了几个关键发现以及未来研究的机会。个人对集体动力及其演变的看法各不相同。在报告本研究的结果时，我们展示了如何对具有实质性兴趣的特征（例如行为相似性的大小和普遍性）进行参数化、解释和汇总。最后，在推进集体同步研究的方法和实质性目标方面，我们强调了几个关键发现以及未来研究的机会。个人对集体动力及其演变的看法各不相同。在报告本研究的结果时，我们展示了如何对具有实质性兴趣的特征（例如行为相似性的大小和普遍性）进行参数化、解释和汇总。最后，在推进集体同步研究的方法和实质性目标方面，我们强调了几个关键发现以及未来研究的机会。
