研究表明，患有自闭症谱系障碍 (ASD) 的人利用绩效反馈来调节自己行为的能力可能会降低；然而，目前尚不清楚环境背景的变化在多大程度上影响反馈处理并导致自闭症谱系障碍的症状。我们利用观察性 FRN (oFRN)，一种事件相关电位 (ERP) 组件，在观察针对另一个人的反馈时，假定对反馈处理进行索引，以检查动机和社会需求对 ASD 反馈处理的影响。研究人员收集了 38 名患有自闭症谱系障碍 (ASD) 的青少年和 31 名年龄和智商相似的对照参与者的高密度脑电图记录，同时观察一名同伙执行修改后的埃里克森侧翼任务。参与者被指示计算同盟者的错误，并被告知他们将根据表现获得奖励；同盟者可以为参与者或她自己赚取积分。两组在传统头皮电极波形和使用时空主成分分析确定的波形上都显示出强大的 oFRN 活性。 oFRN 的幅度不能区分群体。比较服用药物和未服用药物的参与者时，结果仍然不显着。 oFRN 幅度、自闭症症状严重程度和焦虑症状之间没有显着相关性。研究结果表明，任务的社会背景和同盟者表现的动机意义并没有限制自闭症谱系障碍的反馈处理。未来的研究需要进一步操纵环境，以确定环境复杂性的增加是否会影响自闭症谱系障碍的反馈处理。 (C) 2014 Elsevier B.V. 保留所有权利。
Research indicates that individuals with autism spectrum disorders (ASD) may have a reduced ability to utilize performance feedback to regulate their behavior; however, it is unclear to what degree alterations in the environmental context affect feedback processing and contribute to the symptoms of ASD. We utilized the observational FRN (oFRN), an event-related potential (ERP) component that putatively indexes feedback processing while observing feedback directed toward another person, to examine the influence of motivational and social demands on feedback processing in ASD. High-density electroencephalogram recordings were collected from 38 youth with ASD and 31 control participants similar on age and IQ while they observed a confederate performing a modified Eriksen Flanker task. Participants were instructed to count the confederate's errors and were told that they would be awarded based on performance; the confederate would either earn points for the participant or herself. Both groups showed robust oFRN activity on traditional scalp-electrode waveforms and waveforms identified using temporospatial principal components analysis. Amplitude of oFRN did not differentiate groups. Results remained non-significant when comparing medicated to non-medicated participants. There were no significant correlations between oFRN amplitudes, autism symptom severity, and anxiety symptoms. Findings suggest that the social context of the task and motivational significance of the confederate's performance did not limit feedback processing in ASD. Future research in which the context is manipulated further is warranted to determine whether increased environmental complexity influences feedback processing in ASD. (C) 2014 Elsevier B.V.
