Abstract
The effect of experimentally induced cognitive fatigue on divided spatial attention was assessed on a convenience sample of 30 participants, who participated in a dual attention/observation task. Participants were randomly assigned to an “Observer” (Obs) or a “Stimulus Provider” (SP) group. Both groups completed a computerised attention task. The SP group received audio cues to look left, middle or right. The Obs group were asked to note the time and direction they observed the SP group move their head while completing the task. Mental fatigue was induced by the experimental duration (two 25 minute trials). It was hypoFinal Year Projected that as mental fatigue increased, a greater number of errors in one or both of the cognitive tasks would occur, with a corresponding decrease in reaction times. Analysis of these results and their implications in the understanding of the role fatigue in dual-tasking will be discussed with regard to theory and application.
