Abstract:
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.
