Performance In Vigilance Tasks Is Related To Both State And Contextual Motivation

Abstract

Vigilance, or sustained attention, is the ability to maintain attention to stimuli over a prolonged period of time. Synonymous with the study of sustained attention is the vigilance decrement, which is a decline in performance as a function of time on task. In the present study, we examined the effects of state motivation (i.e., motivation measured immediately prior to the task) and context-based motivation (i.e., motivation that stems from task instructions) on vigilance performance in a sensory-based vigilance task. Forty-three participants completed a 24-minute vigilance task, as well as measures of stress and workload. The results indicated that those higher in state intrinsic motivation and motivating instructions outperformed their peers in terms of hits and false alarms. We conclude that motivation may help facilitate vigilant attention.
