目的：
我们调查了参与酗酒的大学生的决策和逆转学习缺陷，以及它们之间的关系。
研究方法：
总共有30名学生参与了暴饮暴食，31名学生参与了非暴饮暴食。酗酒是根据饮酒的数量、频率和速度来定义的。决策和逆向学习分别采用爱荷华州赌博任务（IGT）和逆向学习任务进行测量。
结果如下：
与非狂饮组相比，狂饮组的IGT总净得分显著降低。此外，狂饮组在IGT的第三和第四块中获得了显著较低的块净分数，并且比非狂饮组更频繁地从副牌B（不利）中选择牌。在反向学习任务中，酗酒组在反向学习阶段的正确率显著低于非酗酒组，但在偶然学习阶段的正确率没有显著差异。此外，IGT和反向学习任务的性能之间的关联，观察到在狂饮组，而不是在非狂饮。
结论：
这些结果表明，参与BD的大学生在决策和逆转学习方面存在障碍。难以逆转先前学到的结果可能会导致重复不再有利的选择。
Objectives:
We investigated deficits in decision-making and reversal learning, and the relationship between them in college students who engaged in binge drinking.
Methods:
In total, 30 students involved in binge drinking and 31 non-binge drinking participated. Binge drinking was defined on the basis of the quantity, frequency and speed of alcohol consumption. Decision-making and reversal learning were measured using the Iowa gambling task (IGT) and a reversal-learning task, respectively.
Results:
The binge drinking group obtained significantly lower total net scores on the IGT versus the non-binge drinking group. Additionally, the binge drinking group obtained significantly lower block net scores in the third and fourth blocks of the IGT, and selected cards from deck B (disadvantageous) more frequently than did the non-binge drinking group. In the reversal-learning task, the binge drinking group had significantly lower accuracy than the non-binge drinking group in the reversal-learning stage but not in the contingency-learning stage. Moreover, associations between performance on the IGT and the reversal-learning task were observed in the binge drinking group but not in the non-binge drinking.
Conclusion:
These results indicate that college students participating in BD had impairments in decision-making and reversal learning. Difficulties with reversing previously learned outcomes might lead to repetition of choices that are no longer advantageous.
