酒精线索暴露对引发渴望的影响已经得到了很好的证明，许多理论模型断言，渴望是一个临床上重要的结构，对酒精寻求行为的动机和维持至关重要。此外，一些理论提出了渴望和注意力之间的关系，例如线索诱导的渴望增加会使注意力偏向酒精线索，这反过来又会使渴望持续下去。本研究探讨了在何种程度上酒精线索诱导渴望和偏见的注意力对未成年大学生饮酒者的酒精线索。39名大学本科饮酒者（年龄18-20岁）完成了一项受试者内设计，包括线索反应和视觉探测任务，以评估体内酒精线索暴露对渴望和注意力偏差的影响。参与者表示更大的主观渴望饮酒后，在体内线索暴露于一种常用的啤酒相比，水的曝光。此外，酒精线索曝光后，参与者表现出更大的注意力偏向酒精线索所测量的视觉探测任务。除了线索暴露对渴望和注意力偏差的影响外，受试者内不同时段的渴望差异轻微地预测了受试者内注意力偏差的差异。理论和实践的影响进行了讨论。
The effect of alcohol cue exposure on eliciting craving has been well documented and numerous theoretical models assert that craving is a clinically significant construct central to the motivation and maintenance of alcohol-seeking behavior. Furthermore, some theories propose a relationship between craving and attention, such that cue-induced increases in craving bias attention towards alcohol cues, which in turn perpetuates craving. This study examined the extent to which alcohol cues induce craving and bias attention towards alcohol cues among underage college student drinkers. Thirty-nine undergraduate college drinkers (ages 18–20) completed a within-subjects design that included cue reactivity and visual probe tasks to assess in vivo alcohol cue exposure effects on craving and attentional bias. Participants expressed greater subjective craving to drink alcohol following in vivo cue exposure to a commonly consumed beer compared to water exposure. Furthermore, following alcohol cue exposure, participants exhibited greater attentional biases towards alcohol cues as measured by a visual probe task. In addition to the cue exposure effects on craving and attentional bias, within-subject differences in craving across sessions marginally predicted within-subject differences in attentional bias. Implications for both theory and practice are discussed.
