背景资料：行动监控，评估自己的行动的适当性的过程，据报道是非典型的自闭症谱系障碍（ASD）的个体。方法：我们检查了11名ASD儿童和12名典型发展（TD）儿童的行动监控特征，分析了刺激锁定和反应锁定的事件相关电位成分（即，N2;错误相关负波;结果：ASD儿童的N2波幅比TD儿童小。与TD儿童相比，ASD儿童的部分错误反应（在反应执行之前对应于不适当的手侧的肌电活动）的ERN幅度也更大。此外，部分错误反应的ERN振幅与社会反应量表的自闭症行为相关。ASD儿童和TD儿童的Pe振幅无显著差异。结论：ASD儿童的动作监测在反应执行前后存在显著差异。我们假设，ASD的细节为重点的处理风格减少了响应执行前的动作监测的要求，然而，自闭症的习性引起过度关注响应执行后的微不足道的错误。
Background: Action monitoring, the process for evaluating the appropriateness of one’s own actions, is reported to be atypical in individuals with autism spectrum disorder (ASD).Method: We examined the characteristics of action monitoring in 11 children with ASD and 12 children with typical development (TD), analyzing stimulus-locked and response-locked event-related potential components (i.e., N2; error-related negativity, ERN; and error positivity, Pe) related to execution of a flanker task.Results: We found a smaller N2 amplitude in children with ASD than in those with TD. Children with ASD also had a larger amplitude of ERN for partial error responses (electromyographic activity corresponding to the inappropriate hand side before response execution) than did children with TD. Additionally, the ERN amplitude for the partial error response was correlated with the Autistic Mannerisms of the Social Responsiveness Scale. There were no significant differences in Pe amplitudes between children with ASD and those with TD.Conclusion: The results suggest that action monitoring in children with ASD is significantly different both before and after response execution. We hypothesized that the detail-focused processing style of ASD reduces the demands of action monitoring before response execution; however, autistic mannerisms evoke excessive concern regarding trivial mistakes after response execution.
