| Abstract |
The feasibility of using event-related brain potentials (ERPs) to measure dynamic changes in mental workload was examined. Subjects performed two tasks, monitoring and mental arithmetic, both separately and together. An analysis was made of performance, subjective workload ratings and average ERP data as measured from recordings of electroencephalographic activity. The data are discussed with respect to real-time assessment of mental workload. Results provide tentative support for the use of ERPs as measures of momentary fluctuations in mental workload. |
