Comparison of subjective workload ratings and performance measures of a reference IVIS task

The aim of this study was to establish subjective workload ratings (NASA-TLX) for the ADAM surrogate reference task (SURT) and compare them to ratings of a test battery of real IVIS tasks while participants performed a surrogate of the driving task (Lane Change Task).

Description
Summary:The aim of this study was to establish subjective workload ratings (NASA-TLX) for the ADAM surrogate reference task (SURT) and compare them to ratings of a test battery of real IVIS tasks while participants performed a surrogate of the driving task (Lane Change Task). The results indicated that subjective workload ratings were comparable for both the real and reference tasks, performance measures were significantly correlated with measures of subjective workload and that performance of the secondary reference task declined as task difficulty increased. Reasons for the pattern of results are discussed.
