Abstract Details

2006, MA, University of Cincinnati, Arts and Sciences : Psychology.
The utility of a new measure of perceived mental workload in vigilance, the Multiple Resources Questionnaire (MRQ), was evaluated by comparing it against a standard measure in that area, the NASA-TLX, in sensitivity to the effects of factors theoretically predicted to affect task demand, event asynchrony and search asymmetry (detecting stimulus presence/absence). Contrary to expectation, the former had little impact upon performance but the latter did; detection probability was significantly greater when critical signals for detection were defined by stimulus presence than stimulus absence. This effect was echoed in higher workload scores for absence than presence when workload was measured by the NASA-TLX but not by the MRQ, indicating poorer sensitivity for the new instrument. On the other hand, the MRQ did identify resources utilized in the vigilance task that are not reflected in the standard measure. Therefore, the new scale could be a useful adjunct to the older one.
