错误相关负电位（ERN）及其理论解释

错误动作发生后，在个体额叶中部可观察到一个明显的负相电位偏移，这称为“错误相关负电位”（error related negativity，ERN）。有研究者提出了“强化学习理论”，认为ERN反映了当前行为结果与预期之间的差异。与此不同的是“冲突监控理论”，认为ERN与反应冲突有关。还有研究者提出了“失匹配理论”，强调实际反应的神经表征（错误反应）与当前任务所要求的反应表征的差异产生了ERN。在阐述ERN的理论解释基础上，对三者之间的关系进行了分析与整合。

Error Related Negativity(ERN)and Its Theoretic Interpretations

A negativity deflection is found after an error,which is called the error-related negativity(ERN).Based on the relationship between ERN and error detection,the reinforcement learning theory was put forward to interpret the undergoing mechanism,suggesting that the ERN is associated with the arrival of a negative reward prediction.However,it is also found that ERN seems to appear not only following an error,but also under the condition of a correct response.To account for the relationship between ERN and the ...
