Identifying neurocognitive mechanisms involved in individuals experiencing eating disorder (ED) symptoms may be important for preventing EDs and improving rates of recovery. The present pilot study assessed how cognitive functioning may be associated with ED symptoms in college students (N = 41). Cognitive functioning was examined using electroencephalography during an auditory response inhibition task to measure the P3 component of event-related potentials. Multiple regression analysis revealed that longer P3 latencies in the frontal region of the cortex were significantly and linearly associated with greater ED symptoms F(3, 37) = 13.62, p < .001, R2 = 0.525, Adj. R2 = 0.486. These pilot findings build upon prior work in clinical samples in that they indicate that functional brain differences are observable across a wide span of ED symptoms, not just in those with diagnosed ED. The present findings provide support for further exploration of changes in P3 latencies among individuals with ED symptoms to enhance our understanding of neural mechanisms that may pertain to the dimensional aspects of disordered eating attitudes and behaviors.

与认知加工相关的进食障碍症状的维度检查：事件相关电位研究

确定患有饮食失调 (ED) 症状的个体所涉及的神经认知机制对于预防 ED 和提高恢复率可能很重要。本初步研究评估了认知功能如何与大学生（N = 41）的 ED 症状相关联。在听觉反应抑制任务期间使用脑电图检查认知功能，以测量事件相关电位的 P3 成分。多元回归分析显示，皮质额叶区较长的 P3 潜伏期与更严重的 ED 症状显着线性相关 F(3, 37) = 13.62, p < .001, R2 = 0.525, Adj. R2 = 0.486。这些初步研究结果建立在临床样本的先前工作的基础上，因为它们表明在广泛的 ED 症状中可以观察到功能性大脑差异，不仅仅是那些被诊断出 ED 的人。目前的研究结果为进一步探索 ED 症状个体 P3 潜伏期的变化提供了支持，以增强我们对可能与饮食态度和行为紊乱的维度方面有关的神经机制的理解。
