摘　　要：15名被试在摄入酒精BAL≤ 0 .5‰前后的四个时段内接受一套简单的运算操作任务 ,近 2 / 3被试的认知 -操作能力显示受酒精影响发生变异 :酒后 30分钟操作时间延滞 ,至 6 0分钟更具显著性 ;同时 ,操作错误亦大幅上升 ,但变化趋势不同于操作时间。酒精干扰呈现认知“近视”与“远视”的迹象。subjects took part in a series of arithmetic operation tasks during four testing sessions of no drinking and drinking (BAL<=0.5 0/00). There were some variations of alcohol effect associated with the operation in nearly 2/3 of the participants: Their operation timing delayed evidently in 30 minutes after drinking, and in the 60 minute session the variances of timing reached a remarkably high level; their operation errors rose greatly though not synchronizing with the error. There were indications of 'alcohol myopia' or 'alcohol hyperopia'.
