Previous evidence suggests that emotion regulation (ER) is strongly involved in reward-related food intake in binge eating disorder (BED). However, the mechanisms that link ER to binge eating in BED are largely unclear. At the same time, fundamental research from other domains has repeatedly shown an improved (reduced) cognitive control under usage of adaptive (maladaptive) ER strategies.The aim of the present project is to investigate whether the effect of ER on binge eating is mediated by its effects on food-related cognitive control. We assume that adaptive ER increases food-related cognitive control and thereby reduces binge episodes in individuals with BED.First, using multiple occasion assessment (EMA) over a period of two weeks we will investigate time-lagged associations between ER skills application, food-related cognitive control (using an established reaction-time paradigm) and subsequent binge episodes in a large BED sample. Second, to test for causal links, we will conduct a laboratory-based experiment, in which we will manipulate ER following a negative mood induction. Food-related cognitive control as well as food intake in a bogus taste test will be the outcome measures.

先前的证据表明，情绪调节（ER）强烈参与奖励相关的食物摄入暴食症（BED）。然而，将ER与BED中的暴食联系起来的机制在很大程度上尚不清楚。与此同时，来自其他领域的基础研究一再表明，在使用适应性（适应不良）ER策略的情况下，认知控制得到改善（减少）。本项目的目的是调查ER对暴饮暴食的影响是否是通过其对食物相关认知控制的影响来介导的。我们假设，自适应ER增加食物相关的认知控制，从而减少暴饮暴食发作的个人BED.First，使用多场合评估（EMA）在一段时间内的两个星期，我们将调查ER技能的应用程序，食物相关的认知控制（使用一个既定的反应时间范式）和随后的暴饮暴食发作之间的时滞关联在一个大的BED样本。其次，为了检验因果关系，我们将进行一个实验室实验，在这个实验中，我们将在消极情绪诱导后操纵ER。食物相关的认知控制以及食物摄入量在假味觉测试将是结果的措施。
