Abstract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10 h的出租车司机.采用听觉Oddball范式,以800 Hz纯音为标准刺激(概率80%),1 000 Hz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.
Other AbstractEvent-related potentials(ERPs) index has been used to investigate the character of auditory automatic information-processing after hours' continuous driving.Auditory intensity mismatch negativity(MMN) was recorded and analyzed from 12 taxi drivers after enough rest as control group and 15 taxi drivers having been driving for 10 hours as fatigue group by using Neuroscan EEG/ERPs system.Results indicated that 10 hours' continuous driving resulted in significant enlargement of MMN amplitude compared with control group,exhibiting left frontal region predominant effect.Latency of the right brain region were significantly prolonged.These findings suggest that subjects after 10 hours' continuous driving may process excessively with auditory stimuli change and lack the ability of processing useful information.Conclusion: Automatic process of unrelated information can be strengthened after driving fatigue,which will increase the risk of driving.
