Abstract

As an index of task workload, the possible advantages of the event-related brain potential (ERP) over traditional secondary task techniques and psychophysiological measures are described and previous efforts to validate the use of ERPs in this context are discussed. A series of six experiments is then reported in which the effects of tracking difficulty and display-monitoring load manipulations on secondary-task reaction time and ERP measures are compared. The results are interpreted within the framework of a "multiple reservoir" conception of processing resources and task workload.
