错误相关负波（error-related negativity，ERN）是由错误行为和错误操作反馈刺激诱发的事件相关脑电位。在这项研究中，作者报告了两个实验，在这些实验中，参与者试图通过试错来学习在反应选项之间进行选择，使用反馈刺激来指示货币收益和损失。结果表明，ERN的幅度是由相对于可能的结果范围的诱发结果的价值，而不是由结果的客观价值。这一结果是根据最近的理论进行讨论的，该理论认为ERN反映了与用于强化学习的神经系统相关的奖励预测误差信号。
The error-related negativity (ERN) is an event-related brain potential elicited by error commission and by presentation of feedback stimuli indicating incorrect performance. In this study, the authors report two experiments in which participants tried to learn to select between response options by trial and error, using feedback stimuli indicating monetary gains and losses. The results demonstrate that the amplitude of the ERN is determined by the value of the eliciting outcome relative to the range of outcomes possible, rather than by the objective value of the outcome. This result is discussed in terms of a recent theory that holds that the ERN reflects a reward prediction error signal associated with a neural system for reinforcement learning.
