理论基础：对药物相关线索的注意偏差有相当大的理论兴趣。然而，对这种注意偏差的组成过程的研究却很少。目的：我们研究了重度和轻度社交饮酒者对酒精相关线索的初始导向和注意力的维持。方法：本研究采用视觉探测任务来调查酒精相关线索的视觉定向偏差。我们改变了酒精相关图片的呈现时间（200,500或2000毫秒），以调查注意力偏差是在初始定向还是在注意力维持中起作用。结果：与轻度社交饮酒者相比，重度社交饮酒者对较长时间（500和2000 ms）呈现的酒精图片有注意偏倚，而对较短时间（200 ms）呈现的酒精图片没有注意偏倚。主观酒精渴望与2000 ms酒精图片的注意偏倚指数相关。结论：这些结果表明，重度社交饮酒者对酒精相关线索的视觉导向偏差主要发生在与注意力维持有关的过程中。
Rationale: There has been considerable theoretical interest in attentional biases for drug-related cues. However, there is little research on the component processes of such attentional biases. Objectives: We examined initial orienting to, and the maintenance of attention on, alcohol-related cues in heavy and light social drinkers. Methods: The present study used a visual probe task to investigate biases in visual orienting to alcohol-related cues. We varied the presentation duration of alcohol-related pictures (200, 500 or 2000 ms) to investigate whether attentional biases operated in initial orienting or the maintenance of attention. Results: In comparison with light social drinkers, heavy social drinkers had an attentional bias for alcohol pictures which were presented at the longer exposure durations (500 and 2000 ms), but not at the shorter duration of 200 ms. Subjective alcohol craving was correlated with the attentional bias index for alcohol pictures presented for 2000 ms. Conclusions: These results suggest that biases in visual orienting to alcohol-related cues in heavy social drinkers operate mainly in the processes involved in the maintenance of attention.
