Abstract：
Situation awareness (SA) in complex socio-technical systems is considered a key cognitive activity, as control crews are often engaged in simultaneous task processes and are required to monitor and evaluate system parameters, making decisions and projections for the future accordingly. However, measuring SA at the team level is still a challenging area of research within the topic. In our research, we applied verbal protocol analysis as an alternative method to assess nuclear power plant control room crews\' team SA. We conducted a study of 10 control room crews, examining their intrateam communication and its relatedness to team performance. We have found that communication categories related to the second and third levels of team SA increased significantly after the onset of an emergency event. Furthermore, while none of the team communication categories was related to team performance before the emergency event, all of them showed a strong positive correlation with team performance after the emergency situation occurred. Our results underline the importance of adequate verbalization of key information within the team, so as to support the rapid and accurate development of team SA during emergency situations.
摘要：
复杂社会技术系统中的情境意识(SA)被认为是一种关键的认知活动，由于控制人员通常同时进行任务过程，并且需要监视和评估系统参数，对未来做出相应的决策和预测。然而,在团队层面测量SA仍然是该主题内具有挑战性的研究领域。在我们的研究中,我们将口头协议分析作为评估核电厂控制室机组SA团队的替代方法。我们对10名控制室人员进行了研究，检查他们的内部沟通及其与团队绩效的相关性。我们发现，在紧急事件发生后，与SA团队的二级和三级相关的沟通类别显着增加。此外，虽然没有团队沟通类别与紧急事件前的团队表现有关，紧急情况发生后，所有这些都与团队绩效呈较强的正相关。我们的结果强调了团队内部关键信息充分口头表达的重要性，以便在紧急情况下支持团队SA的快速准确发展。
