Throughout training and team performance, teams may be assessed based on their communication patterns to identify which behaviors contributed to the team’s performance; however, this process of establishing meaning in communication is burdensome and time consuming despite the low monetary cost. A current topic in team research is developing covert measures, which are easier to analyze in real-time, to identify team processes as they occur during team performance; however, little is known about how overt and covert measures of team process relate to one another. In this study, we investigated the relationship between overt (communication) and covert (neural) measures of team process by manipulating the interaction partner (participant or experimenter) team members worked with and the type of task (decision-making or action-based) teams performed to assess their effects on team neural synchronization (measured as neurodynamic entropy) and communication (measured as both flow and content). The results indicated that the type of task affected how the teams structured their communication but had unpredictable effects on the neural synchronization of the team when averaged across the task session. The interaction partner did not affect team neural synchronization when averaged. However, there were significant relationships when communication and neural processes were examined over time between the neurodynamic entropy and the communication flow time series due to both the type of task and the interaction partner. Specifically, significant relationships across time were observed when participants were interacting with the other participant, during the second task trial, and across different regions of the cortex depending on the type of task being performed. The findings from the time series analyses suggest that factors that are previously known to affect communication (interaction partner and task type) also structure the relationship between team communication and neural synchronization—cross-level effects—but only when examined across time. Future research should consider these factors when developing new conceptualizations of team process measurement for measuring team performance over time.

使用通信来调节团队中的神经同步

在整个培训和团队绩效期间，可以根据团队的沟通模式对团队进行评估，以确定哪些行为对团队绩效有所贡献；然而，尽管货币成本很低，但这种在沟通中建立意义的过程是繁重和耗时的。团队研究的当前主题是开发更易于实时分析的隐蔽措施，以识别团队绩效期间发生的团队流程；然而，人们对团队过程的公开和隐蔽措施之间的相互关系知之甚少。在这项研究中，我们通过操纵互动合作伙伴（参与者或实验者）团队成员一起工作以及执行的任务类型（决策或基于行动的）团队来评估团队过程的公开（沟通）和隐蔽（神经）措施之间的关系它们对团队神经同步（以神经动力学熵衡量）和交流（以流量和内容衡量）的影响。结果表明，任务类型影响团队如何构建他们的沟通，但在任务会话中平均时对团队的神经同步有不可预测的影响。平均时，互动伙伴不影响团队神经同步。然而，由于任务类型和交互伙伴，当随着时间的推移检查神经动力学熵和通信流时间序列之间的通信和神经过程时，存在显着的关系。具体而言，当参与者与其他参与者互动时，在第二个任务试验期间，以及根据正在执行的任务类型，跨越皮层的不同区域时，观察到了跨时间的显着关系。时间序列分析的结果表明，以前已知的影响沟通的因素（互动伙伴和任务类型）也构建了团队沟通和神经同步之间的关系——跨层次效应——但只有在跨时间检查时才会如此。
