目的探讨驾驶疲劳对于听觉非随意注意的影响。方法采用组间对照，对照组为13名充分休息的出租车司机，驾驶疲劳组为13名连续驾驶10h的出租车司机。采用听觉Oddball范式，以800Hz纯音为标准刺激（概率80％），1000Hz纯音为靶刺激（概率10％），计算机产生的噪声或其他声音为新异刺激（概率10％）。要求被试者对靶刺激进行按键反应。结果对照组新异刺激产生的P3a以额中央区分布为主；与对照组相比，驾驶疲劳组的P3a幅值显著降低。结论驾驶疲劳后听觉非随意注意能力下降。 |

Objective To investigate effects of driving fatigue on auditory involuntary attention, Method Between-groups design was used, The control group included 13 taxi drivers after adequate rest while the fatigue group included 13 taxi drivers who had been driving for 10 h. Auditory oddball pattern was adopted. The standard stimulus was 800 Hz, probability 80%; target stimulus was 1 000 Hz, probability 10%; novel stimulus was sound generated by computer or other sound, probability 10%. Subjects were asked to press the mouse upon hearing the target sound. Result The distribution of P3a was mainly around the frontal-central area of the subjects in control group;the amplitude of P3a was evidently lowered in subjects after driving fatigue, Conclusion The ability of auditory involuntary attention declines after driving fatigue. |
