Abstract

Understanding the operator's cognitive workload is crucial for efficiency and safety in human–machine systems. This study investigated how cognitive workload modulates cardiac autonomic regulation during a standardized military simulator flight. Military student pilots completed simulated flight tasks in a Hawk flight simulator. Continuous electrocardiography was recorded to analyze time and frequency domain heart rate variability (HRV). After the simulation, a flight instructor used a standardized method to evaluate student pilot's individual cognitive workload from video-recorded flight simulator data. Results indicated that HRV was able to differentiate flight phases that induced varying levels of cognitive workload; an increasing level of cognitive workload caused significant decreases in many HRV variables, mainly reflecting parasympathetic deactivation of cardiac autonomic regulation. In conclusion, autonomic physiological responses can be used to examine reactions to increased cognitive workload during simulated military flights. HRV could be beneficial in assessing individual responses to cognitive workload and pilot performance during simulator training.

模拟军事飞行中与认知工作量有关的心脏自律神经反应

了解操作员的认知工作量对人机系统的效率和安全至关重要。本研究调查了认知工作量如何调节标准化军事模拟器飞行过程中的心脏自主神经调节。军事学生飞行员在 Hawk 飞行模拟器中完成了模拟飞行任务。连续心电图记录分析了时域和频域心率变异性（HRV）。模拟飞行结束后，飞行教官使用标准化方法，通过飞行模拟器视频记录数据评估学生飞行员的个人认知工作量。结果表明，心率变异能够区分引起不同程度认知工作量的飞行阶段；认知工作量的增加导致许多心率变异变量显著下降，这主要反映了副交感神经对心脏自主神经调节的失活。总之，在模拟军事飞行中，自律神经生理反应可用于检查对认知工作量增加的反应。心率变异有助于评估个人对认知工作量的反应以及模拟器训练期间飞行员的表现。
