The Vigilance Decrement Reflects Limitations
Robertson, Manly, Andrade, Baddeley, and Yiend (1997) proposed that the decline in performance efficiency over time in vigilance tasks (the vigilance decrement) is characterized by "mindlessness" or a withdrawal of attentional effort from the monitoring assignment. We assessed that proposal using measures of perceived mental workload (NASA-TLX) and stress (Dundee Stress State Questionnaire). Tw...
متن کاملAdaptive measurement of vigilance decrement.
Research investigated the utility of an alternative technique for the study of vigilance performance. The usual approalch has been to study how well subjects responded to a signal of given difficulty; this technique altered the difficulty of the task to ensure a fixed level of performance. A computer-based, self-adjusting program presented background stimuli--a pair of dots 4.25 inches apart di...
متن کاملChewing gum moderates the vigilance decrement.
We examine the impact of chewing gum on a Bakan-type vigilance task that requires the continual updating of short-term order memory. Forty participants completed a 30-min auditory Bakan-task either with, or without, the requirement to chew gum. Self-rated measures of mood were taken both pre- and post-task. As expected, the vigilance task produced a time-dependent performance decrement indexed ...
متن کاملThe role of memory representation in the vigilance decrement.
Working memory load is critically important for the overall level of performance on vigilance tasks. However, its role in a key aspect of vigilance-sensitivity decrement over time-is unclear. We used a dual-task procedure in which either a spatial or a nonspatial working memory task was performed simultaneously with a spatial vigilance task for 20 min. Sensitivity in the vigilance task declined...
متن کاملRelationship of Event-Related Potentials to the Vigilance Decrement
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 variety of experimental methodologies have been used to investigate cognitive fatigue in vigilance, relatively little research has utilized electroencephalography (EEG), specifically event-related potentials (ERPs)...
