Successful interaction requires complex coordination of body movements. Previous research has suggested a functional role for coordination and especially synchronization (i.e., time-locked movement across individuals) in different types of human interaction contexts. Although such coordination has been shown to be nearly ubiquitous in human interaction, less is known about its function. One proposal is that synchrony supports and facilitates communication (Topics Cogn Sci 1:305-319, 2009). However, questions still remain about what the properties of coordination for optimizing communication might look like. In the present study, dyads worked together to construct towers from uncooked spaghetti and marshmallows. Using cross-recurrence quantification analysis, we found that dyads with loosely coupled gross body movements performed better, supporting recent work suggesting that simple synchrony may not be the key to effective performance (Riley et al. 2011). We also found evidence that leader-follower dynamics-when sensitive to the specific role structure of the interaction-impact task performance. We discuss our results with respect to the functional role of coordination in human interaction.
成功的互动需要身体动作的复杂协调。先前的研究表明，协调，尤其是同步（即个体之间的时间锁定运动）在不同类型的人际互动情境中具有功能性作用。尽管这种协调在人际互动中几乎无处不在，但其功能却鲜为人知。一种观点认为，同步支持并促进交流（《认知科学专题》1:305 - 319，2009年）。然而，关于优化交流的协调属性可能是什么样子，仍然存在问题。在本研究中，两人一组合作，用生意大利面和棉花糖搭建塔楼。通过交叉递归量化分析，我们发现身体总体动作耦合松散的两人组表现更好，这支持了最近的研究成果，即简单同步可能不是有效表现的关键（莱利等人，2011年）。我们还发现有证据表明，领导者 - 跟随者动态关系——当对互动的特定角色结构敏感时——会影响任务表现。我们将结合协调在人际互动中的功能作用来讨论我们的研究结果。
