以ＢＤＸＬ－Ⅱ型注意力分配测试仪对某汽车队１７７名驾驶员和１３９名非驾驶员进行了注意力分配检查，并计算每人注意力分配量Ｑ值。结果表明，驾驶员组注意力分配及视、听觉反应速度有随年龄和驾车年数增长而下降的趋势，Ｑ值及视、听觉反应测试得分与对照组相比差异有显著性。 A BDXL-II attention distribution tester was used to examine the attention distribution of 177 drivers and 139 non-drivers in a certain automobile fleet and to calculate the Q value of each individual’s attentional allocation. The results showed that the driver’s attention distribution and auditory and auditory response rate decreased with the increase of age and number of driving years. There was significant difference between Q value, visual acuity and auditory reaction test scores and the control group.
