Robertson, Manly, Andrade, Baddeley, and Yiend (1997) have proposed that detection
failures in vigilance tasks result from a 'mindless' withdrawal of attentional effort from the …

Robertson, Manly, Andrade, Baddeley, and Yiend (1997) proposed that the decline in
performance efficiency over time in vigilance tasks (the vigilance decrement) is …

The longer we are required to monitor for rare but critical events, the accuracy and speed
with which we detect such events tend to suffer (the 'vigilance decrement') with more difficult …

It is well known that when human observers must monitor for rare but critical events,
probability of detection tends to wane over time, a phenomenon known as the “vigilance …

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 …

Many vigilance tasks require discrimination of infrequent signal events from frequent
nonsignals. During performance on these tasks signal detections often decline. But this does …

Vigilance, or the ability to sustain attention for extended periods of time, has been of interest
to the human factors and ergonomics community for 70 years. During this time, several …

Vigilance or sustained attention/vigilant attention refers to the ability of observers to maintain
their focus of attention and remain alert to stimuli over prolonged periods. A variety of …

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 …

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 …
