酗酒会扰乱核心的执行功能，包括工作记忆(WM)--维护和操纵与目标相关的信息的能力。当像WM这样的执行功能被削弱时，饮酒行为就会失控，并受到更强的自动冲动的引导。这项研究调查了训练WM是否恢复了对饮酒行为的控制。48名问题饮酒者在至少25天的25次会议中进行了WM培训任务或控制任务。训练前后分别测量白质和饮酒行为。训练后1个月以上，WM改善WM，减少饮酒量。此外，通过改善WM训练对酒精使用的间接影响被参与者的自动冲动水平所缓和：在对酒精具有相对较强的自动偏好的参与者中，WM增加减少了酒精消耗量。这些发现与理论框架一致，并表明训练WM可能是一种通过增加对饮酒自动冲动的控制来减少饮酒的有效策略。
Alcohol abuse disrupts core executive functions, including working memory (WM)-the ability to maintain and manipulate goal-relevant information. When executive functions like WM are weakened, drinking behavior gets out of control and is guided more strongly by automatic impulses. This study investigated whether training WM restores control over drinking behavior. Forty-eight problem drinkers performed WM training tasks or control tasks during 25 sessions over at least 25 days. Before and after training, we measured WM and drinking behavior. Training WM improved WM and reduced alcohol intake for more than 1 month after the training. Further, the indirect effect of training on alcohol use through improved WM was moderated by participants' levels of automatic impulses: Increased WM reduced alcohol consumption in participants with relatively strong automatic preferences for alcohol. These findings are consistent with the theoretical framework and demonstrate that training WM may be an effective strategy to reduce alcohol use by increasing control over automatic impulses to drink alcohol.
