摘要: Individuals need feedback from the context to determine success of their actions. In present study, explicit process judgement (explicit response correctness) was examined by recording ERPs. A systematic mismatch between expected information and observed (incorrect feedback) linked subject's performance used. Thirteen subjects participated in they were required detect correct vs. incorrect with an response. The experimental procedure included three main tasks: (spatial decisional task); system's (external feedback); external (feedback monitoring). FRN (feedback-related negativity) ERP effect a higher amplitude revealed case monitoring for feedback. Moreover, as shown cortical source analysis (LORETA), erroneous produced significant increased right prefrontal area. This negative deflection may be viewed specific marker conscious functions. Considering distribution this effect, whereas anterior portion cingulate cortex could represent more automatic cognitive processing mismatching, dorsolateral area would intervene reconfigure subjective expectations when violation is consciously detected. Generally, system explain significance mechanism necessity restore incoherent information.
