Abstract:

Age-related declines in the ability to select targets in a visual clutter across an extended visual field has been identified as a major cause of higher crash risks among older drivers. An effective measure of target detection in a cluttered driving scene could be useful to inform about an older driver’s decline in attentional abilities and the potential influence on driving safety. This paper describes the development and initial examination of a task, the Drive Aware Task, designed to measure attentional abilities in the context of driving. The authors conducted two experiments to investigate the effectiveness of the task. Their results showed that older drivers’ performance on the Drive Aware Task was associated with performance on a cognitive task measuring attentional visual field, suggesting that the Drive Aware Task is a valid measure of attentional abilities among older drivers. Performance on the task also revealed significant age differences. Compared to younger drivers, older drivers in general performed worse on the Drive Aware Task; however, the size of age differences varied among different task conditions (travelling left, right or straight). Moreover, older drivers’ performance on the Drive Aware Task was consistent with their performance on simulated driving. This evidence demonstrates the effectiveness of the Drive Aware Task. This task can potentially be a useful measure of attentional abilities in the context of driving, such as an assessment tool for cognitive fitness-to-drive among older drivers.
