This study examines the relation between the error-related negativity (ERN) and post-error behavior over time in healthy young adults (N=61). Event-related brain potentials were collected during two sessions of an identical flanker task. Results indicated changes in ERN and post-error accuracy were related across task sessions, with more negative ERN associated with greater improvements in post-error accuracy. This relationship was independent of any cross-sectional relationships between overall task performance, individual difference factors, including personality and self-efficacy, and indices of self-regulatory action monitoring. These results indicate that the relation between ERN and post-error accuracy remains intact and consistent regardless of variation in this set of individual difference factors previously associated with both of these indices of self-regulatory action monitoring, providing support for the strength, robustness, and persistence of this relationship in the process of adaptively controlling behavior to enhance task performance.
本研究考察了健康年轻成年人（N=61）在一段时间内错误相关负波（ERN）与错误后行为之间的关系。在两个相同的侧抑制任务的会话中采集了事件相关脑电位。结果表明，ERN 和错误后准确性的变化在任务会话之间是相关的，更负的 ERN 与错误后准确性的更大提高相关。这种关系独立于总体任务表现、包括个性和自我效能在内的个体差异因素以及自我调节行动监测的指标之间的任何横断面关系。这些结果表明，ERN 与错误后准确性之间的关系保持不变且一致，无论先前与这两个自我调节行动监测指标相关的个体差异因素的变化如何，为在适应性控制行为以提高任务表现的过程中这种关系的强度、稳健性和持久性提供了支持。
