Samenvatting
This paper describes research aimed to test the role of general attentional resources in driving performance against two criteria for resource-limitation which are said to be more rigorous than dual-task interference alone. The main performance measure in the driving simulator was heading error, the driver's mean deviation from the direction of the road. The results suggest that caution is necessary in trying to use measurements of cognitive load as a guide to dual-task interference. The data suggest that auditory systems may be more difficult to combine with driving than are visual systems. Drivers may be able to acquire the skill of combined auditory and visual encoding with relatively little practice.
