Abstract
The aim of this study was to understand how visual and auditory dual tasks impact upon the driving behavior of young and old participants. The effect of a secondary task on measures of driving performance including the recognition of road signs, detection and avoidance of large low contrast road hazards, judgment of cone gaps, and time to complete the course was assessed for young and older participants as they drove around a 5 km closed road driving course. The secondary task required participants to verbally report the sums of pairs of numbers presented either through a computer speaker (auditorially) or via a dashboard mounted monitor (visually) while driving. The results show that drivers reported fewer road signs, increased their time to complete the road course, and misjudged cone gaps more frequently under the dual-task (visual and auditory) conditions compared to the single task condition and these effects were greater for the older participants.
