| 摘要： | In this experiment, 32 licensed drivers (16 young, 16 old) drove on an expressway. On each trial (96 per subject), 1 to 3 traffic messages containing 6 to 14 items were presented. (l-94 eastbound at Southfield freeway, continuing construction, right lane blocked, 3 mile backup.). Imagining they were driving from Ann Arbor to Detroit on l-94, subjects identified messages relevant to that route and recalled them. Messages were either of good or poor audio quality (to simulate poor reception). |
