模拟飞行条件下双重任务时飞行员心理生理参数的变化特点

测量了50名健康飞行员和13名康复疗养飞行员，在模拟飞行条件下双重任务时的心理生理反应。结果发现，模拟飞行各阶段心率变化趋势与实际飞行基本一致，但变化幅度较低。双重任务时，反映情绪性变化的心率、呼吸率及肺通气量明显增加，与思维活动有关的眨眼率增加。心理运动反应速度与飞行操纵质量相互影响，其程度有个体差异。同时在该负荷环境下，发现5例心律失常的无症状飞行员。结果提示，模拟飞行双重任务条件可以造成飞行员心理生理负荷，并可能有助于发现一些潜在性病症。

Changes in psychophysiological indices in pilots during dual task flight on a simulator

Psychophysiological response of 50 healthy pilots and 13 pilots in vacation were mea-sured under dual task condition on a simulator. The results showed that physiological responses of pilotsin simulated flight were consistent with those in real flight on the same segment except the difference instrength. The heart rate,respiration rate,and pulmonary ventilation volume associated with emotion laswell as the blink rate related with thinking process were increased in the dual task simulation. The psy-chological choice reaction speed and the flight performence effected each other,but the degrees of influ-ence were different among individuals. Five arrhythmia cordis were induced in pilots who used to behealthy by load of the dual task on simulator,but did not bring out by exercise load. The results sug-gested that the dual task on simulator can cause workload on pilot and may be beneficial in finding outlatent diseases in pilots.
