Relatively little is known about the relation between subthreshold error corrections and post-error behavioral compensations. The present study utilized lateralized beta power, which has been shown to index response preparation, to examine subthreshold error corrections in a task known to produce response conflict, the Simon task. We found that even when an overt correction is not made, greater activation of the corrective response, indexed by beta suppression ipsilateral to the initial responding hand, predicted post-error speeding, and enhanced post-error accuracy at the single-trial level. This provides support for the notion that response conflict associated with errors can be adaptive, and suggests that subthreshold corrections should be taken into account to fully understand error-monitoring processes. Furthermore, we expand on previous findings that demonstrate that post-error slowing and post-error accuracy can be dissociated, as well as findings that suggest that frontal midline theta oscillations and the error-related negativity (ERN) are dissociable neurocognitive processes.

亚阈值误差校正预测自适应误差后补偿

关于亚阈值误差校正和误差后行为补偿之间的关系知之甚少。本研究利用已被证明可以索引响应准备的横向 beta 功率来检查已知会产生响应冲突的任务（西蒙任务）中的亚阈值误差校正。我们发现，即使没有进行明显的纠正，纠正反应的更大激活，由与初始反应手同侧的 beta 抑制索引，预测错误后的速度，并在单次试验级别提高错误后的准确性。这为与错误相关的响应冲突可以是自适应的概念提供了支持，并建议应考虑亚阈值更正以充分理解错误监控过程。此外，
