Even though eating is frequently driven by overindulgence and reward rather than by energy balance, few studies so far have analyzed decision-making processes and disturbances in feedback processing in women with binge eating disorder (BED). In an experimental study, 17 women with BED (DSM-IV) and 18 overweight healthy controls (HC) were compared in the game of dice task (GDT). This task assesses decision-making under risk with explicit rules for gains and losses. Additionally, differences in dispositional activation of the behavior inhibition and behavior approach system as well as cognitive flexibility were measured. Main results revealed that women with BED make risky decisions significantly more often than HC. Moreover, they show impaired capacities to advantageously utilize feedback processing. Even though these deficits were not related to disease-specific variables, they may be important for the daily decision-making behavior of women with BED, thus being relevant as a maintenance factor for the disorder.
尽管进食常常是由过度放纵和奖励驱动的，而不是由能量平衡驱动的，但到目前为止，很少有研究分析过暴食障碍（BED）女性的决策过程和反馈处理障碍。在一项实验研究中，17 名患有 BED（DSM-IV）的女性和 18 名超重健康对照组（HC）在掷骰子游戏（GDT）中进行了比较。该任务评估了在明确的收益和损失规则下的风险决策。此外，还测量了行为抑制和行为趋近系统的特质性激活以及认知灵活性的差异。主要结果表明，BED 女性比 HC 女性更频繁地做出冒险决策。此外，她们在利用反馈处理方面的能力受损。尽管这些缺陷与特定疾病的变量无关，但它们可能对 BED 女性的日常决策行为很重要，因此作为该障碍的维持因素很重要。
