焦虑与过度活跃的行动监控过程有关，这是通过错误相关消极性（ERN）来衡量的。然而，担心是不相关的错误相关的行为调整，这通常是用来推断增加认知控制以下错误。我们假设，过度活跃的行动监测和未改善的错误后调整之间的这种脱节是由于减少功能整合的内侧和外侧前额叶区域之间的生成过程中的ERN，理解有一个重要的作用，在调解控制处理。为了验证这一点，我们研究了ERN振幅和通道间相位同步提取的头皮记录脑电图数据在错误处理过程中，在77名本科生谁执行了侧卫任务。相关分析和路径分析结果表明，焦虑既与扩大的ERN有关，也与减少的相位同步有关。虽然没有直接相关的错误后的行为调整，结果还显示，担心是间接相关的错误后的调整，通过其与减少相位同步。因此，忧虑似乎会影响行动监控系统的多个组成部分。它不仅与错误的初始反应有关，而且与认知控制过程中网络之间的信息传输有关。
Worry is reliably associated with overactive action-monitoring processes as measured by the error-related negativity (ERN). However, worry is not associated with error-related behavioral adjustments which are typically used to infer increased cognitive control following errors. We hypothesized that this disconnect between overactive action monitoring and unimproved post-error adjustments in worriers is the result of reduced functional integration between medial and lateral prefrontal regions during generation of the ERN, understood to have an important role in mediating controlled processing. To test this, we examined ERN amplitude and interchannel phase synchrony extracted from scalp-recorded electroencephalographic data during error processing in 77 undergraduates who performed a Flankers task. Correlational and path analytic results demonstrated that worry was related to both an enlarged ERN and reduced phase synchrony. Although not directly related to post-error behavioral adjustments, results also revealed that worry was indirectly related to poor post-error adjustments through its association with reduced phase synchrony. Therefore, worry seems to affect multiple components of the action-monitoring system. It is related not just with the initial response to the error, but also with the transmission of information between networks involved in cognitive control processes.
