Prolonged cognitive effort can be considered one of the core determinants of mental fatigue
and may negatively affect the efficacy and efficiency of cognitive performance. Metacognition …

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 …

The end-spurt effect, where performance declines with time-on-task and then increases
toward the end of a task, has garnered little attention in the vigilance literature. Researchers …

Performance on the psychomotor vigilance test (PVT; Dinges & Powell, 1985)—a common
index of sustained attention—is affected by the opposing forces of fatigue and sustained …

Recently, the gamma band (γ; 70-100 Hz) has been implicated in sustained attention decay
across a vigil consistent with computational models of fatigue. Frontal γ indexing centrally …

Research has shown multiscale entropy, brain signal behavior across time scales, to reliably
increase at lower time scales with time-on-task fatigue. However, multiscale entropy has not …

Abstract The Predatory Imminence Continuum Theory proposes that defensive behaviors
depend on the proximity of a threat. While the neural mechanisms underlying this proposal …

We used Granger prediction (GP) to assay fatigue effects in a 3-stimulus oddball task
requiring context-sensitive proactive control to evaluate top-down frontal-parietal and bottom …

The identification of a single neuroelectrophysiological measure of differential performance
across time in a fatigued state remains elusive, especially where a single marker would …

Bridges are an integral component of infrastructure in the United States. Current inspection
practices are expensive, lack quality, and pose safety risks to inspectors. A solution to many …
