卡车驾驶员视觉选择性注意研究

A STUDY OF TRUCK DRIVERS’ VISUAL SELECTIVE ATTENTION

采用注意力测验量表，对２８０名男性卡车驾驶员的视觉选择性注意进行了测量。研究发现：事故组与安全组卡车驾驶员的完成时间、漏划数和平均每秒正确删数有很显著差异，错划数有显著差异；事故多发组与安全组卡车驾驶员的完成时间和平均每秒删数有很显著差异，错划数有显著差异；年龄对卡车驾驶员的视觉选择性注意有显著影响，随着年龄的增加，卡车驾驶员完成视觉选择性注意作业的时间增长，漏划数和错划数增多，平均每秒正确删数减少，而４０－５０岁则是卡车驾驶员视觉选择性注意速度和准确性下降的转折点。

The Visual Selective Attention Scale was adopted to measure the visual selective attention(VSA ) OF 280 male truck drivers. The results were as follows: 1) The difference of completing time,ornissions, errors and number of correct deletion per second between safe and accident truck drivers was significant: 2) The difference of the three items between accident repeaters and safe drivers was significant. Accident drivers had longer completing time, more omissions, more errors and smaller number of correct deletions per second than safe drivers; 3)Age had a significant impact on drivers' VSA.Increase in age led to more inefficient performance of VSA:longer completing time I more omissions, more errors and smaller number of correct deletions per second. The age of 40--50 was the turning point for speed and accuracy decline of VSA.
