The effects of air traffic conflict geometry have been well investigated in prior studies, particularly in the context of the pilot, though little in the context of the air traffic control officer (ATCO). No study to date has investigated the effects of conflict geometry on human factors variables of ATCOs through objective and physiological approaches. This study examines the effects of conflict geometries on ATCO situation awareness, stress level and brain activity during conflict resolution. Fifteen participants were instructed to resolve six different conflict geometries: crossing level, crossing non-level, converging level, converging non-level, overtaking level, and overtaking non-level. The results indicate that converging and crossing conflicts led to lower situation awareness (SA), higher stress level, and higher theta activation at the temporal and parietal lobes. Level conflict led to lower SA. The findings offer two implications, providing insights for the formal guidelines in ATC conflict resolution training and provision of inputs for the conflict resolution aid development.

基于脑电图的空中交通冲突分析：调查冲突解决过程中管制员的态势感知、压力水平和大脑活动

空中交通冲突几何的影响在之前的研究中已经得到了很好的研究，特别是在飞行员的背景下，尽管在空中交通管制官（ATCO）的背景下很少。迄今为止，还没有研究通过客观和生理方法研究冲突几何对 ATCO 人为因素变量的影响。本研究考察了冲突几何对 ATCO 态势感知、压力水平和冲突解决过程中大脑活动的影响。15 名参与者被要求解决六种不同的冲突几何形状：交叉水平、交叉非水平、会聚水平、会聚非水平、超车水平和超车非水平。结果表明，融合和交叉冲突导致较低的态势感知（SA）、较高的压力水平、在颞叶和顶叶有更高的 theta 激活。级别冲突导致较低的 SA。研究结果提供了两个含义，为 ATC 冲突解决培训中的正式指南提供了见解，并为冲突解决援助开发提供了投入。
