In this report, we examined the impact of rest breaks and goal switches on the vigilance
decrement—the change in performance with time-on-task—and subjective stress and …

The dominant theory amongst vigilance researchers is resource theory. From this theoretical
perspective the increase in lapses with time on task, the vigilance decrement, is due to the …

The vigilance decrement has been described as a slowing in reaction times or an increase
in error rates as an effect of time-on-task during tedious monitoring tasks. This decrement …

We examined the impact task interruptions have on visuospatial vigilance in two
experiments. In the first experiment participants were randomly assigned to one of three …

In the experiments presented here, we examined the impact of intervening tasks on the
vigilance decrement. In Experiment 1 participants either (a) continuously performed a …

The vigilance decrement is a decline in signal detection rate that occurs over time on a
sustained-attention task. The effect has typically been ascribed to conservative shifts of …

Objective: We examined the impact task interruptions of differing qualitative and quantitative
load have on visuospatial vigilance sensitivity. Background: The vigilance decrement and …

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 …

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 …

Previous research has shown opposite effects of dual tasking on the vigilance decrement
phenomenon. We examined the executive (ie, detecting infrequent critical signals) and …
