Physiological synchronization of autonomic arousal between people is thought to be an important component of work team dynamics, therapist-client relationships, and other interpersonal dynamics. This article examines concepts and mathematical models of synchronization that could be relevant to work teams. Before it is possible to deploy nonlinear modeling, however, it is necessary to develop a strategy for determining appropriate lag lengths. If a measurement at time 2 is a function of itself at time 1 and a coupling effect from another source, what is the appropriate amount of real time that should be allowed to elapse between the two measurements in order to observe the coupling effect? This study examined four strategies for doing so. In the experiment, 78 undergraduates worked in pairs to perform a vigilance dual task for 90 min while galvanic skin responses (GSR) were recorded. Lags based on mutual entropy and the natural rate criteria produced corroborating results, whereas strategies based on a critical decline in the linear autocorrelation (max r/e) and Theiler's W did not produce usable results for this situation. Some connections were uncovered between linear autocorrelation strength and lag based on mutual entropy with performance on the tasks and subjective ratings of workload.
人们之间自主唤醒的生理同步被认为是工作团队动态、治疗师与客户关系以及其他人际动态的重要组成部分。本文探讨了可能与工作团队相关的同步概念和数学模型。然而，在能够部署非线性建模之前，有必要制定一种确定适当滞后长度的策略。如果时间2的测量值是其自身在时间1的值以及来自另一个源的耦合效应的函数，那么为了观察耦合效应，两次测量之间应该允许经过多长的实际时间才合适？本研究考察了四种这样做的策略。在实验中，78名本科生两人一组进行90分钟的警觉性双重任务，同时记录皮肤电反应（GSR）。基于互熵和自然率标准的滞后产生了相互印证的结果，而基于线性自相关的临界下降（最大r/e）和泰勒W的策略在这种情况下没有产生可用的结果。在线性自相关强度和基于互熵的滞后与任务表现和工作量主观评分之间发现了一些联系。
