The ERN-Ne of the event-related potential indicates error monitoring. Even though enlarged ERN-Ne amplitudes have often been related to higher anxiety scores, a recent meta-analysis provided very small effect sizes for the association of trait-anxiety with the ERN-Ne. Conditions modulating this association were investigated in the present study: (1) The generality of the trait-anxiety factor, (2) gender, and (3) experimental conditions, i.e., worry induction and error aversiveness. Participants (48% men) completed a flanker task. Worries were induced before the task by giving participants ( = 61) a bogus feedback claiming their responses were slower than the average responses of participants, whereas other participants ( = 61) got the feedback that they responded as fast as other participants. Aversiveness of errors was varied by playing sinus tones after too slow responses in one part of the task (no-scream condition) and aversive screams after too slow responses in another part (scream condition). Increased ERN-Ne amplitudes of response time errors occurred for individuals higher on trait-anxiety in the condition with induced worries and screams. A multiple group model for women and men indicated that women are more sensitive to conditions altering the association of trait-anxiety with the ERN-Ne.
事件相关电位的ERN-Ne表明错误监测。尽管ERN-Ne波幅增大常常与更高的焦虑得分相关，但最近一项荟萃分析显示特质焦虑与ERN-Ne之间关联的效应量非常小。本研究对调节这种关联的条件进行了调查：（1）特质焦虑因素的普遍性，（2）性别，以及（3）实验条件，即担忧诱导和错误厌恶程度。参与者（48%为男性）完成了一项侧翼任务。在任务前通过给参与者（n = 61）虚假反馈称其反应比其他参与者的平均反应慢来诱导担忧，而其他参与者（n = 61）得到的反馈是他们的反应与其他参与者一样快。在任务的一部分中，对反应过慢播放正弦音（无尖叫条件），在另一部分中对反应过慢播放厌恶的尖叫声（尖叫条件），以此改变错误的厌恶程度。在诱导担忧和尖叫的条件下，特质焦虑程度较高的个体在反应时间错误上出现ERN-Ne波幅增加。针对女性和男性的多组模型表明，女性对改变特质焦虑与ERN-Ne之间关联的条件更敏感。
