模拟应急条件下的反应时研究

The Reaction Times under the Condition of Simulating Air Critical Situation on the Ground.

本研究用模拟任务负荷和紧张情绪负荷法分别测定了１０８名健康男性（其中５６名飞行员）和９名航空试验用锻炼员对应急信号做出反应并完成应急操纵动作所用的时间（ＲＴ＋ＭＴ），在平静无负荷状态下测定了４５名健康男性对声、光信号的反应时间ＰＲＴ。结果表明，飞行员组的（ＲＴ＋ＭＴ）在训练前后分别平均为１．７２５５和１．２７３５，对声、光信号的ＰＲＴ平均值分别为０．２７２５（声）、０．３１２ｓ（红）、０．３０３ｓ（绿）、０．３０２ｓ（蓝）；飞行员组与普通被试组无显著差异；紧张因素的影响未达显著程度；训练因素能显著提高反应能力。

The times of reacting to air critical signals and completing air critical operations(RT+ MT)were determined by the methods of simulating task-load and stress-load on the ground.108 healthy men(of whom 56 were Air Force pilots ) and 9 trainees for aviation medicine tests served as subjects. In addition to this, the times to sound and light signals were measured in 45 healthy male subjects in usual state. The results showed that,before and after training, the mean values of (RT+MT) of the Air Force pilots were 1.725s and 1. 273s respectively. The mean values of PRT to sound and light signals were successively 0.272s(sound),0.312s(red),0.303s(green)and 0.302s (blue).There was no significant difference between the groups of pilots and ordinary healthy men.The effect of stress was not significant.However,training can increase the reacting ability significantly.
