Abstract: Abstract Using Electroencephalography (EEG), this study aims at extracting three features from instantaneous mental workload measure and link them to different aspect of the workload construct. An experiment was designed to investigate the effect of two workload inductors (Task difficulty and uncertainty) on extracted features along with a subjective measure of mental workload. Results suggest that both subjective and objective measures of workload are able to capture the effect of task difficulty; however only accumulated load was found to be sensitive to task uncertainty. We discuss that the three EEG measures derived from instantaneous workload can be used as criteria for designing more efficient information systems.
