疲劳对交通系统安全具有重大影响；因此，研究与疲劳的心理生理联系可以增强我们对运输行业疲劳的理解和管理。这项研究检查了 35 名随机选择的受试者在驾驶模拟器任务期间发生的心理生理变化。结果表明，疲劳时脑电图发生显着变化。发现 Delta 和 theta 活性在疲劳期间显着增加。驾驶任务后心率明显降低。疲劳任务期间眨眼率也会发生变化。研究表明，特质焦虑、紧张焦虑、疲劳惰性和活力活动减少与疲劳的神经生理学指标（例如 Delta 和 Theta 活动增加）相关。根据未来研究和疲劳对策装置开发的方向讨论了结果。
Fatigue has major implications for transportation system safety; therefore, investigating the psychophysiological links to fatigue could enhance our understanding and management of fatigue in the transport industry. This study examined the psychophysiological changes that occurred during a driver simulator task in 35 randomly selected subjects. Results showed that significant electroencephalographic changes occur during fatigue. Delta and theta activity were found to increase significantly during fatigue. Heart rate was significantly lower after the driving task. Blink rate also changed during the fatigue task. Increased trait anxiety, tension-anxiety, fatigue-inertia and reduced vigor-activity were shown to be associated with neurophysiological indicators of fatigue such as increased delta and theta activity. The results are discussed in light of directions for future studies and for the development of a fatigue Countermeasure device.
