Individual Differences in Vigilance and Performance During Continuous/Sustained Operations
Abstract
Military operations are often characterized by prolonged periods of wakefulness; irregular rest-activity patterns; long haul flights. These situations are unnatural. Severe sleep debt can accumulate, leading to dangerous levels of sleepiness and decreases of performance. Although sleep deprivation, time of day and time on task are considered among the most important causal factors of daytime sleepiness, the levels of vigilance may still significantly vary according to individual differences. Verifying whether and to what extent some stable individual differences are associated to specific variations of vigilance and performance may be important in orienting the best criteria for the selection of personnel involved in prolonged activity for many hours or unusual hours, and/or monotonous activity.
