本研究考察了健康老年人和极轻度和轻度阿尔茨海默型痴呆（DAT）个体的视觉注意测量与驾驶表现之间的关系。受试者进行道路驾驶评估和三个视觉注意任务（视觉搜索、视觉监测和有用视野）。结果表明，视觉搜索错误率和反应时间是驾驶表现的最佳预测因子。此外，视觉搜索性能可以预测驾驶性能，远远超过简单的痴呆严重程度和几种传统的心理测试。结果表明，一般认知状态可能有助于识别不安全驾驶的“危险”个体。然而，选择性注意的措施可能有助于更好地区分安全与不安全的驾驶员，特别是在DAT人群中。
The present study examined the relationship between visual attention measures and driving performance in healthy older adults and individuals with very mild and mild dementia of the Alzheimer type (DAT). Subjects were administered an on-road driving assessment and three visual attention tasks (visual search, visual monitoring, and useful field of view). The results indicated that error rate and reaction time during visual search were the best predictors of driving performance. Furthermore, visual search performance was predictive of driving performance above and beyond simple dementia severity and several traditional psychometric tests. The results suggest that general cognitive status may be useful for identifying individuals "at risk" for unsafe driving. However, measures of selective attention may serve to better differentiate safe versus unsafe drivers, especially in the DAT population.
