反馈错误相关负性（fERN）是由反馈刺激引起的人类事件相关大脑电位（ERP）的组成部分。最近的理论认为，fERN 索引了与自适应模式相关的奖励预测误差信号。行为的阳离子。在这里，我们展示了参与修改后的时间估计任务的参与者记录的行为和 ERP 数据。正如理论预测的那样，我们的结果表明，fERN 幅度反映了奖励预测误差信号，并且该误差信号的大小与参与者之间任务绩效的变化相关。
The feedback error-related negativity (fERN) is a component of the human event-related brain potential (ERP) elicited by feedback stimuli. A recent theory holds that the fERN indexes a reward prediction error signal associated with the adaptive modi. cation of behavior. Here we present behavioral and ERP data recorded from participants engaged in a modified time estimation task. As predicted by the theory, our results indicate that fERN amplitude reflects a reward prediction error signal and that the size of this error signal is correlated across participants with changes in task performance.
