The error-related negativity (ERN), a well-established neural marker of anxiety, reflects enhanced attention to internal threat signals. While attention to threat plays a crucial role in the development and maintenance of anxiety, it is unclear how attentional control influences the ERN-anxiety association. To address this, 37 youths (M = 10.89 years) completed self-report measures of attentional control and anxiety symptoms. To obtain ERN amplitude, youth completed a flanker task while simultaneous EEG was collected. Attentional control, specifically attentional shifting rather than focusing, moderated the relation between ERN amplitude and anxiety. Youth who displayed smaller neural responses to making an error and higher ability to shift attention experienced lower levels of anxiety, relative to those who exhibited larger neural responses to making an error or lower attention-shifting ability. These findings highlight that response magnitude to internal threat and ability to flexibly shift attention may jointly contribute to anxiety in youth.
错误相关负波（ERN）是焦虑的一种成熟的神经标志物，反映了对内部威胁信号的增强注意力。虽然对威胁的注意力在焦虑的发展和维持中起着至关重要的作用，但目前尚不清楚注意力控制如何影响 ERN-焦虑的关联。为了解决这个问题，37 名年轻人（M=10.89 岁）完成了注意力控制和焦虑症状的自我报告测量。为了获得 ERN 幅度，年轻人在完成侧抑制任务的同时同步采集 EEG。注意力控制，特别是注意力转移，而不是集中注意力，调节了 ERN 幅度与焦虑之间的关系。与表现出对犯错的神经反应较大或注意力转移能力较低的年轻人相比，对犯错的神经反应较小且注意力转移能力较高的年轻人焦虑程度较低。这些发现强调了对内部威胁的反应幅度和灵活转移注意力的能力可能共同导致年轻人的焦虑。
