Abstract:In an attempt to understand the specific mechanism by which distractions (such as cell - phone use) can interfere with driving, this work tested the idea that driving performance depends on available space within visual short - term memory. Across trials, different amounts of available vis ual memory were created by the use of a concurrent visual change - detection task. The results showed the typical decrease in memory performance with higher memory loads, but no significant change in driving performance, other than an overall, non - specific, dual - task deficit. These findings suggest that driving does not depend on the fixed - capacity memory system that is assessed by standard, visual short - term memory tasks.
