Vigilance has recently been considered as two dissociated components: executive and arousal vigilance. The goal of the present study was to investigate the brain oscillatory rhythms underlaying the failures in both vigilance components. Participants were 37 young adults (age: M = 25.86; SD = 4.99), who completed two experimental sessions in which they performed the ANTI-Vea, a ~38-minute task that simultaneously measures the executive and arousal vigilance components, while the electroencephalography signal was recorded. Changes in delta (1-4 Hz), theta (4-8 Hz), alpha (8-14 Hz), beta (14-30 Hz) and gamma (30-45 Hz) frequency rhythms were analyzed, overall, and during the time before the appearance of the response stimulus. The association between these oscillatory rhythms and performance in executive vigilance (hits vs. errors and first vs. last blocks) and arousal vigilance (fast vs. slow responses and first vs. last blocks) was investigated. Results show that, while a reduction in alpha power predicts hits in the executive vigilance component, a smaller increase in delta power predicts a faster response in arousal vigilance. The implications of these findings will be discussed.
