Abstract:The role of C1 and P1 component as the early event-related potential that emerges from the striate cortex at 60ms to 150ms after stimulus onset has not widely studied for vigilance state monitoring. In this study, we developed a new radar-like display that consists of a white and red moving triangle that appears in the upper and lower visual display as a target and non-target stimulus. The task performance was measured with signal detection theory and reaction time, the electroencephalography data that was recorded during the task was analyzed with Event-Related Lateralization’s. Statistical results showed that the vigilance decrement occurred as the effect of the block in d-prime, beta and reaction time. However, the modulation of ERLs activity in three different time windows (60-90ms, 90-120ms, and 120-150) were not affected by the block. There was no significant effect of the stimuli position, and there was no interaction effect between the block and the stimuli. Therefore, further studies with improved methods and optimized stimuli are required before C1 and P1 component can be used for real-time vigilance state monitoring.
