The processing of feedback is essential for learning, error detection, and correction. However, the underlying mechanisms of the feedback's characteristics, such as its reliability, valence, and expectations in the processing of error information, are not completely clear. The two degrees of feedback reliability, reliable feedback and unreliable feedback, respectively, were established by manipulating the feedback valence. The time course of event-related potentials (ERP) during the arrow flanker tasks was used to investigate the effects of feedback reliability and responses on brain activity. Three ERP components, the error-related negativity (ERN), feedback-related negativity (FRN), and P3, respectively, were measured. The impacts of feedback reliability and responses on ERN, FRN, and P3 had a different profile. Specifically, ERN and P3 are associated with the responses but not the feedback reliability, while FRN is associated with feedback reliability and feedback expectations but not the responses. The ERN, FRN, and P3 reflect distinct cognitive processes in the processing of error information.
反馈的处理对于学习、错误检测和纠正至关重要。然而，反馈特征的潜在机制，如可靠性、效价和对错误信息处理的期望，尚不完全清楚。通过操纵反馈效价，分别建立了两种反馈可靠性，即可靠反馈和不可靠反馈。使用事件相关电位（ERP）的时间历程来研究反馈可靠性和反应对大脑活动的影响。分别测量了三个 ERP 成分，即错误相关负波（ERN）、反馈相关负波（FRN）和 P3。反馈可靠性和反应对 ERN、FRN 和 P3 的影响具有不同的特征。具体来说，ERN 和 P3 与反应有关，而与反馈可靠性无关，而 FRN 与反馈可靠性和反馈期望有关，而与反应无关。ERN、FRN 和 P3 反映了错误信息处理中不同的认知过程。
