Abstract: For the sake of investigating the influence of fatigue on the mental fatigue of drivers, ERP-based experiments were carried out. In the experiments, the mental rotation ability of drivers was determined before and after they fulfilling a 2-hour simulated driving task respectively. Based on the experimental data, the change and variability in behavioral performance (reaction time, accuracy) and ERP component (amplitude and latency of P3) before and after the driving fatigue were analyzed. It was found that driving fatigue decreased the behavior performance significantly (delayed reaction time, decreased accuracy), and the ERP component P3's amplitude decreased and latency delayed significantly in the parietal lobe. The conclusion the authors arrived at is that fatigue influences the allocation of cognitive resources and the speed of information processing of drivers in mental rotation process, resulting in undermining the mental rotation ability.
