摘　　要：酒精饮料作为世界六大饮料之一,深受大众喜爱。适量地饮用酒精饮料可以缓解焦虑,产生愉悦体验。但酒精的摄入对认知控制的具体影响方式尚不清晰。研究采用AXCPT任务,考察酒精对认知控制方式的影响。实验中两组被试在实验处理前后分别完成两次实验任务,进而对比两次完成任务的情况。结果显示,实验组的被试饮酒之后各类试次的反应时显著缩短,正确率显著降低,AY序列的正确率降低尤为显著。控制组的被试在实验处理之后,其正确率与实验处理前没有显著差异。这表明酒精能够影响个体的认知控制方式和持续性注意,使个体的认知控制在饮用酒精之后,更加倾向于主动性控制。Bevarage with alcohol,one of the six bavarages,is very popular.Proper drinking of bavarage with alcohol can reduce anxiety and produce pleasure experience.This study pays attention to the cognitive control strategy of participants after drinking.In the study,participants were engaged in a task that is called AX-CPT（AX-continuous performance test）to study the effects of alcohol on cognitive control strategy.Thirty-four participants were examined with this task before and after the experiment processing.The results suggested that,individuals have the less reaction time and the more error rate after the experiment processing,especially in the AY trials.It shows that,primarily,practice effect does exist;importantly,it is alcohol that makes the reaction of the AY trials so awful.In conclusion,alcohol has an impact on cognitive control strategy,thus it affects the continuous attention.The specific performance is that drinking alcohol makes the individuals significantly tend to proactive control.
