The synchronization of autonomic arousal levels within dyads and larger teams has become a potentially important variable in the explanation of team performance and group processes. Synchronization research with groups of three or more members has been challenging because of limited means for quantifying relationships that are more extensive than dyads. This article presents an empirical investigation of group performance and participation using a new synchronization coefficient that is grounded in nonlinear dynamical systems theory. We introduce the concept of a driver, a person with whom the group tends to synchronize the most, and an empath, a person who is most synchronized with other team members. Fifty-five undergraduate research participants, who were organized into 11 groups of three or four participants, played six emergency response simulations against an opponent while generating electrodermal data. Results showed that greater physiological synchronization resulted from better team performance and greater par-ticipation levels. Synchronization was higher for groups of four team members compared to three. Synchronization was also observed between the opponent and team members. Further opportunities for using the synchronization coefficient in group process research are discussed.
二元组及更大团队中自主唤醒水平的同步，已成为解释团队绩效和群体过程的一个潜在重要变量。由于量化三人或三人以上群体关系的手段有限，这类群体的同步研究颇具挑战性，因为这类关系比二元组更为广泛。本文采用基于非线性动力系统理论的新同步系数，对群体绩效和参与情况进行实证研究。我们引入了“驱动者”这一概念，即群体最倾向于与之同步的人，以及“共情者”，即与其他团队成员同步性最高的人。55名本科研究参与者被分成11个由三四名参与者组成的小组，在与对手进行六次应急响应模拟时生成了皮肤电数据。结果表明，更好的团队绩效和更高的参与水平带来了更强的生理同步性。与三人组相比，四人团队的同步性更高。在对手和团队成员之间也观察到了同步性。本文还讨论了在群体过程研究中使用同步系数的更多机会。
