焦虑中与威胁相关的注意力中断可能与任务处理过程中认知控制的变化有关。本研究采用N2事件相关脑电位对这一问题进行了研究。有人预测，威胁刺激将选择性地影响N2的特质焦虑升高，减少N2可能反映了一个补偿过程预测更好的注意力表现。EEG记录，而36名参与者完成了一个提示侧翼任务的威胁或非威胁分心。N2振幅更大的不一致与一致的侧翼。以下的威胁，高特质焦虑的参与者表现出减少调制的N2的侧翼类型和更大的N2振幅一致的侧翼。减少N2与更好的注意力表现有关。这项研究是第一个记录N2的情绪调节与威胁偏见及其与焦虑中的注意力干扰的联系。
Threat-related attentional disruptions in anxiety may relate to changes in cognitive control during task processing. The present study examined this question using the N2 event-related brain potential. It was predicted that threat stimuli will selectively influence the N2 for those showing elevated trait anxiety and that reduced N2 may reflect a compensatory process predicting better attention performance. EEG was recorded while 36 participants completed a cued flanker task with threat or nonthreat distracters. N2 amplitudes were greater to incongruent versus congruent flankers. Following threat, high trait anxious participants showed reduced modulation of the N2 by flanker type and greater N2 amplitudes to congruent flankers. Reduced N2 was associated with better attention performance. This study was among the first documenting the emotional modulation of the N2 related to the threat bias and its links with attention interference in anxiety.
