The Effect of Drinking on Driver's Visuospatial Working Memory 2001-01-0044
Working Memory (WM) span is highly associated with complex cognitive tasks. Since driving is a complex cognitive task, it is suggested that working memory is highly associated with it. To verify this hypothesis, We designed five tasks, namely, two memory span tasks: visuospatial WM task and visuospatial memory task; and three reaction time tasks: simple reaction time, select reaction time and successive reaction time. By testing, we proved that: (1) Drinking had a great effect on driver's visuospatial WM, and the effect was mainly on information processing. (2) Driving is a complex cognitive manipulation activity. WM was a critical factor to predict complex cognitive manipulation activities. Therefore, we can use visuospatial WM as an important factor in driver selection and the evaluation of driving performance.
