Abstract
- • Differences in hazard reaction time and ERP performance of young novice drivers with different sleep states were compared. • Sleep-deprived drivers performed significantly worse in the no-hazard situation regarding response accuracy and N1 latency. • N2 amplitude is a good indicator that responds to different types of hazards. The present study aimed to explore the effects of sleep deprivation on young novice drivers' cognitive neural processing of different hazard types. A 2 (sleep deprivation group, control group) × 3 (no hazard, covert hazard, overt hazard) mixed experimental design was used. Twenty-eight young drivers were sleep-deprived (no sleep within the past 24 h), while 28 drivers were in the control group (maintaining a normal schedule throughout the week). Eighty pictures containing a covert hazard (20 pictures), overt hazard (20 pictures) and no hazard (40 pictures) were presented. Participants were asked to press the keyboard quickly if they detected a hazard situation. The reaction time, accuracy, and changes in the N1 (100–150 ms) and N2 (250–350 ms) components of event-related potentials (ERP) measured using electroencephalography (EEG) were obtained. Compared to the control group, the response accuracy of sleep-deprived drivers was higher in the cover-hazard situation and their N1 latency was longer in the no-hazard situation. Compared to the no-hazard and overt-hazard situations, the participants' reaction times and N2 amplitudes were significantly greater, and the response accuracy was significantly lower in the covert-hazard situation. Hazard perception is compromised when drivers are sleep-deprived, especially when they are confronted with covert hazard situations. The findings help understand the negative effects of sleep deprivation in the early stage of young novice drivers' hazard perception. [ABSTRACT FROM AUTHOR]
