Models posit problematic binge-watching to involve a vicious circle of low motivation for alternative activities, low sensitivity for the consequences of neglected goals, and low self-control. As such, simultaneously impaired feedback and inhibitory functioning might contribute to binge-watching. We tested the hypothesis that blunted feedback-related brain activity is coupled with attenuated inhibitory brain activity in binge-watchers. High (n = 32) and non-binge-watchers (n = 31) performed go/nogo (inhibition) and stop signal (stopping) tasks and a flanker paradigm with performance feedback during electroencephalography. We examined how neural correlates of inhibition and stopping were associated with outcome processing in each group. We assessed the temporospatial relationship using a single-trial regression approach. High binge-watchers, but not non-binge-watchers, who differentiated less between gains and losses at the neural level (feedback-P3b) also recruited less brain activity during both inhibition and stopping (inhibition-P3 and stopping-P3). Exploratory analyses suggested that these relationships were most prominent in high binge-watchers with high loss of control over watching. Main effects of the group in performance or EEG did not emerge. These results suggest a potentially problematic interaction between outcome and inhibitory functions in binge-watchers. Insensitivity to behavioral consequences along with inhibitory impairments may also confer a long-term risk for compulsive watching. Our multi-modal approach may be particularly suited to detect such an underlying risk marker.

运动抑制受损和结果处理受损的皮层电相关性与高度暴饮暴食有关

模型假设有问题的暴饮暴食涉及一个恶性循环，即替代活动的动机低、对被忽视目标的后果的敏感性低以及自我控制能力低。因此，同时受损的反馈和抑制功能可能会导致暴饮暴食。我们测试了这样一个假设，即与反馈相关的大脑活动迟钝与狂欢观察者的抑制性大脑活动减弱相结合。高（n  = 32）和非暴饮暴食者（n = 31) 执行 go/nogo (抑制) 和停止信号 (stopping) 任务以及在脑电图期间具有性能反馈的侧卫范例。我们检查了抑制和停止的神经相关性如何与每组的结果处理相关联。我们使用单试验回归方法评估了时空关系。高狂欢观察者，但不是非狂欢观察者，他们在神经水平（反馈-P3b）的收益和损失之间的差异较小，在抑制和停止期间（抑制-P3和停止-P3）也招募了较少的大脑活动。探索性分析表明，这些关系在高度暴饮暴食的观看者中最为突出，并且对观看的控制权丧失很大。该组在表现或脑电图方面的主要影响没有出现。这些结果表明，暴饮暴食者的结果和抑制功能之间存在潜在的问题相互作用。对行为后果的不敏感以及抑制性损伤也可能导致强迫观看的长期风险。我们的多模式方法可能特别适合检测这种潜在的风险标记。
