Abstract

In this study, the differential effects of focal and ambient visual demand on driving were investigated. Subjects participated in a dual-task experiment in which they performed a driving simulation task and a focal or ambient side-task. It was predicted that the focal side-task would cause a significant deterioration in the maintenance of longitudinal control but not lateral control, while there should be no effects of the ambient side-task on driving performance. In general, the results suggest a differentiation in the processing demands of focal and ambient vision.
