Previous research has demonstrated that alcohol impairs information processing. However, it is unknown whether this impairment is on all stages of information processing, or on the early, rather than on the later, stages of information processing. Thus, the aim of the present study was to examine the effects of orally administered alcohol on both the early and the later stages of information processing. The present study assessed inspection time (IT), simple reaction time, choice reaction time and cognitive ability (Wechsler Adult Intelligence Scale - Revised) in 16 adult participants in both alcohol and placebo conditions. IT (a measure of the early stages of information processing) was used as a predictor variable in a linear regression to examine whether a disruption of the early stages of information processing accounted for changes in total information processing after alcohol administration. Results indicated that alcohol significantly slowed total information processing, independently of the early stages of information processing.
先前的研究表明，酒精会损害信息处理能力。然而，尚不清楚这种损害是发生在信息处理的所有阶段，还是仅发生在信息处理的早期阶段而非后期阶段。因此，本研究的目的是检验口服酒精对信息处理早期和后期阶段的影响。本研究评估了16名成年参与者在饮酒和服用安慰剂两种情况下的检查时间（IT）、简单反应时间、选择反应时间和认知能力（韦氏成人智力量表修订版）。IT（信息处理早期阶段的一种测量指标）被用作线性回归中的预测变量，以检验信息处理早期阶段的中断是否导致饮酒后总信息处理能力的变化。结果表明，酒精显著减慢了总信息处理速度，且与信息处理的早期阶段无关。
