摘要： 前注意是指在注意之前对事物进行该不该注意分析的心理过程, 它对人适应不断变化的环境具有很重要的作用。近年来一些研究者用失匹配负波(Mismatch Negtivity, MMN)作为前注意加工的ERP指标探讨了酒精对人前注意加工的影响, 结果发现：1)急性摄入超过0.3g/kg的酒精, 人的MMN波幅会显著减小, 波峰潜伏期显著延长; 2)长期慢性摄入酒精, 人的MMN不仅表现为波幅减小和波峰潜伏期延迟, 而且在戒断酒精之后, MMN又会逐渐恢复正常; 3)有酒精成瘾家族史的子代的MMN没发现异常。这些研究结果说明酒精的急性和慢性摄入会损害人的前注意加工, 但尚未发现这种损害会影响到下一代的证据。

Abstract: Pre-attention is the mental process of determining whether or not to attend a stimulus before focusing on it. It is very important for human being to adapt to the environment full of changes. Recently, researchers have examined the effect of alcohol on pre-attention through MMN studies. These results show that: a. The amplitude of MMN decreases significantly and its peak latency delays significantly after drinking a dose more than 0.3g/kg alcohol; b. As to the condition of chronic drinking (eg. chronic alcoholism), the amplitude of MMN decreases and its peak latency delays. However, MMN recovers gradually after absent from alcohol; c. MMN of children from alcoholism families shows no difference from children from normal families. These results indicate that acute and chronic alcohol drinking impair pre-attentive processing. However, there is hardly any evidence showing that it will impair pre-attentive processing of the next generation.
