Résumé
To assess the effects of workload pressures, participants interacted with a modified version of air trafficcontrol simulated tasks requiring different levels of cognitive resources. Changes in mental workloadbetween the levels were evaluated multidimensionally using a subjective rating, performance in asecondary task, and other behavioural indices. Saccadic movements were measured using a video-basedeye tracking system. The Wickens multiple resource model is used as a theoretical reference framework.Saccadic peak velocity decreases with increasing cognitive load, in agreement with subjective test scoresand performance data. That saccadic peak velocity is sensitive to variations in mental workload duringecologically valid tasks is demonstrated.
