主体间的相互作用是人类活动的核心。这就是为什么缺乏协调往往是错过目标的原因，而不是个人失败的原因。虽然有不同的主观和客观的措施来评估所需的心理努力的水平，而受试者面临的情况是越来越困难，即心理工作量，定义一个客观的衡量标准的基础上，团队成员是如何互动，如果不是那么简单。在这项研究中，行为，主观和同步脑电图数据收集的夫妇参与合作任务，以描述任务难度和团队协调之间的关系，在意义上的互动，旨在合作执行任务。多脑连接分析提供了关于整个交互系统的信息。结果表明，任务难度对脑网络的平均局部特性有影响。特别是，强度变化显着的任务难度和聚类系数强烈相关的工作量本身。特别是，较高的工作量对应于较低的聚类值在中央和顶叶脑区。这种结果被解释为当受试者的活动由于高工作量倾向而不太协调时，网络的组织效率较低。
Subjects’ interaction is the core of most human activities. This is the reason why a lack of coordination is often the cause of missing goals, more than individual failure. While there are different subjective and objective measures to assess the level of mental effort required by subjects while facing a situation that is getting harder, that is, mental workload, to define an objective measure based on how and if team members are interacting is not so straightforward. In this study, behavioral, subjective and synchronized electroencephalographic data were collected from couples involved in a cooperative task to describe the relationship between task difficulty and team coordination, in the sense of interaction aimed at cooperatively performing the assignment. Multiple-brain connectivity analysis provided information about the whole interacting system. The results showed that averaged local properties of a brain network were affected by task difficulty. In particular, strength changed significantly with task difficulty and clustering coefficients strongly correlated with the workload itself. In particular, a higher workload corresponded to lower clustering values over the central and parietal brain areas. Such results has been interpreted as less efficient organization of the network when the subjects’ activities, due to high workload tendencies, were less coordinated.
