Vigilant attention is a major component of a wide range of cognitive performance tasks.
Vigilant attention is impaired by sleep deprivation and restored after rest breaks and (more …

Sustained attention is one of the basic abilities of humans to maintain concentration on
relevant information while ignoring irrelevant information over extended periods. The …

Objective The purpose of this study was to compare a psychomotor vigilance task developed
for use on touchscreen devices with the original PVT-192 in conditions of acute sleep loss …

Fatigue is a critically important aspect of crew endurance in submarine operations, with
continuously high fatigue being associated with increased risk of human error and long-term …

Cognitive fatigue emerges in wide-ranging tasks and domains, but traditional vigilance tasks
provide a well-studied context in which to explore the mechanisms underlying it. Though a …

The vigilance decrement in sustained attention tasks is a prevalent example of cognitive
fatigue in the literature. A critical challenge for current theories is to account for differences in …

Abstract Study Objectives The time-on-task (TOT) effect and total sleep deprivation (TSD)
have similar effects on neurobehavioral functioning, including increased performance …

Introduction There is a need to develop a comprehensive account of time-on-task fatigue
effects on performance (ie, the vigilance decrement) to increase predictive accuracy. We …

Sustained attention is an essential behavior in life, but often leads to performance
decrements with time. Computational accounts of sustained attention suggest this is due to …

Objective Patients with chronic excessive daytime sleepiness (EDS) complain of substantial
attention deficits. However, their underlying neuronal dysfunction is largely unknown …
