对酒精的注意偏向是一种有据可查的效应，饮酒者将更多的视觉注意力分配给酒精相关的刺激，而不是非食欲的中性刺激。最近的一些研究表明，急性饮酒暂时减少了对酒精线索的注意偏差，可能是因为酒精消费满足了饮酒的动机。然而，这种效应的特异性还没有被测试，因此还不清楚酒精后注意力偏差的减少是否特异于酒精相关的刺激，或者是否对其他食欲刺激（例如食物）的注意力也减少了。这项研究测试了急性酒精管理选择性地减少对酒精相关线索的注意力偏差的程度，而不是在一组23名健康的年轻人中，他们报告每周饮酒约两次。使用视觉点探测任务，在2个主动剂量的酒精后，对酒精相关和食物相关线索的注意偏向进行了测试。30 g/kg和。65 g/kg，和安慰剂。结果表明，注意偏向，测量固定时间刺激的视觉探测任务，酒精线索下降的剂量依赖性方式，而注意偏向食物线索不受剂量的影响。有证据表明，酒精消费特别减少注意力偏差酒精相关的刺激，而其他食欲刺激的偏见保持不变。酒精消费减少注意力偏差，特别是酒精线索的证据，进一步的可信度满足理论和效用的注意力偏差作为一个指标的急性和短暂的变化，个人的动机使用酒精。（PsycInfo数据库记录（c）2023阿帕，保留所有权利）
Attentional bias to alcohol is a well-documented effect whereby drinkers allocate greater visual attention toward alcohol-related stimuli rather than nonappetitive, neutral stimuli. Some recent research has shown that acute administration of alcohol temporarily reduces attentional bias to alcohol cues, possibly because alcohol consumption satiates the motivation to drink. However, the specificity of this effect has not been tested, and so it is unclear whether reduced attentional bias following alcohol is specific to alcohol-related stimuli or whether attention to other appetitive stimuli is also reduced (eg, food). This study tested the degree to which acute alcohol administration selectively reduced attentional bias to alcohol-related but not to food-related cues in a group of 23 healthy young adults who reported consuming alcohol roughly twice per week. Attentional bias to alcohol-related and food-related cues was tested using visual dot probe tasks following 2 active doses of alcohol,. 30 g/kg and. 65 g/kg, and a placebo. Results showed that attentional bias, measured as fixation time to stimuli on the visual probe tasks, to alcohol cues declined in a dose-dependent manner, whereas attentional bias to food cues was unaffected by the doses. The evidence suggests that alcohol consumption specifically reduces attentional bias to alcohol-related stimuli whereas bias to other appetitive stimuli remains intact. Evidence that alcohol consumption reduces attentional bias specifically to alcohol cues lends further credibility to the satiation theory and to the utility of attentional bias as an indicator of acute and transient changes in an individual’s motivation to use alcohol.(PsycInfo Database Record (c) 2023 APA, all rights reserved)
