目的：成瘾者对药物线索的注意力增强，从而导致药物使用。然而，很少有研究酒精中毒的个体注意的组成过程。在这里，我们研究了戒酒酒精依赖者和饮酒社交者的注意力的两个不同组成部分，即对酒精相关线索的初始定向和对它们的注意力维持。方法：本研究使用了“酒精”版本的视觉探针检测任务，酒精相关或中性图片被短暂呈现（即，50 ms），以评估初始定向，或更长时间（即，500和1，250 ms），以评估attention.Results：只有酒精中毒患者在检测到与酒精相关的图片出现50 ms后立即显示的探针时，比检测到相同的探针替换非酒精相关图片时更快。然而，当图片被呈现500毫秒时，只有社交饮酒者在检测探针取代酒精场景时更快。在持续时间为1,250毫秒的刺激下，没有一组对酒精线索表现出注意力偏向。此外，酒精中毒的严重程度测量的总人数先前的解毒治疗呈正相关的注意力偏差（或“吸引力”）为酒精图片提出了50毫秒。结论：这些结果表明，在最初的视觉定向酒精相关的线索，禁欲患者的注意力脱离这些刺激，从而表明视觉接近-脱离注意力模式。这些发现对复发的影响进行了讨论。
Objective: Addicted people are characterized by enhanced attention for drug cues leading to drug use. However, there is little research on the component processes of attention in individuals with alcoholism. Here, we examine 2 distinct components of attention in abstinent alcohol-dependent individuals and social drinkers of alcohol, that is to say, the initial orienting to alcohol-related cues, and the maintenance of attention to them.Method: The present study used an "alcohol" version of the visual probe detection task with alcohol-related or neutral pictures being presented briefly (i.e., 50 ms), to assess initial orienting, or longer (i.e., 500 and 1,250 ms), to assess the maintenance of attention.Results: Only alcoholic patients were faster in detecting a probe displayed immediately after pictures related to alcohol presented for 50 ms than in detecting the same probe replacing non-alcohol-related pictures. However, when pictures were presented for 500 ms, only social alcohol drinkers were faster in detecting the probe replacing alcohol scenes. At a stimulus of 1,250 ms duration, no group showed attentional bias toward alcohol cues. In addition, the severity of alcoholism measured by the total number of prior detoxification treatments was positively correlated with the attentional bias (or "attraction") for alcohol pictures presented for 50 ms.Conclusions: These results show that, subsequent to initial visual orienting to alcohol-related cues, abstinent patients' attention was disengaged from these stimuli, thus suggesting a visual approach-disengagement attentional pattern. The influence of these findings on relapse was discussed.
