Abstract

Situation awareness (SA) is a mental state that is instrumental to performance of complex dynamic tasks. SA within teams is thought to be supported by favorable social conditions within the team. The present study was organized in two parts: (a) causal relationships among SA, group cohesion, and autonomic synchrony, the latter being a fundamentally nonlinear process, and (b) the combined impact of the three variables on performance in a dynamic decisions task. Experimental conditions assessed changes in task difficulty, group size, and method of obtaining SA measures. Participants were 136 undergraduates organized into 32 teams of three to five members engaged in two matches of a first-person shooter computer game. They completed self-report measures of cohesion and SA. Synchrony was determined through time series analysis of electrodermal responses using the driver-empath framework. ANOVA results showed that cohesion and SA improved over the two matches, and SA was better in smaller groups during the second match. Synchrony was stronger in larger groups. Granger regression indicated no causal or circular relationship between SA and cohesion. Synchrony had a small positive effect on cohesion during the first match. SA had a strong negative impact on synchrony early on and dissipated afterwards. The best performing teams during the first match were those that: were larger, were measured for SA without pausing the simulation, were less synchronized, showed more accurate SA, and reported stronger cohesion. The study opens new questions concerning the role of synchrony in volatile situations and the role of automated team members operating alongside humans.

团队情境意识、凝聚力和自主同步2:团队层面的影响及其对团队绩效的综合影响。
情境意识(SA)是一种有助于完成复杂动态任务的心理状态。团队内部的SA被认为得到了团队内部有利的社会条件的支持。本研究分为两部分:(a)SA、群体凝聚力和自主同步性之间的因果关系,后者是一个基本上非线性的过程,以及(b)三个变量对动态决策任务中表现的综合影响。实验条件评估了任务难度、小组规模和获得SA测量方法的变化。参与者是136名本科生,分成32个小组,每组3至5人,参加两场第一人称射击电脑游戏。他们完成了内聚力和SA的自我报告测量。通过使用驾驶员移情框架对皮肤电反应进行时间序列分析来确定同步性。方差分析结果显示,在两场比赛中,凝聚力和SA都有所改善,在第二场比赛中,小团体的SA表现更好。较大群体的同步性更强。Granger回归表明SA和内聚力之间没有因果关系或循环关系。Synchrony在第一场比赛中对凝聚力有一个小的积极影响。SA在早期对同步性产生了强烈的负面影响,随后逐渐消散。在第一场比赛中表现最好的球队是那些规模较大、在不暂停模拟的情况下测量SA、同步性较差、SA显示更准确、凝聚力更强的球队。这项研究提出了新的问题,涉及同步在动荡局势中的作用,以及与人类并肩作战的自动化团队成员的作用。
