我们进行了文献综述，以检查错误的积极性（Pe），错误相关的电生理脑电位经常与错误的消极性（Ne）相结合观察的功能意义。审查发现许多解离记录的影响Ne和Pe，这表明这些组件反映了不同方面的错误处理。我们发现很少支持所提出的假设，即PE与情感处理错误或与postterror行为适应。一些支持被发现的假设，即PE反映了有意识地认识到一个错误。最后，我们讨论的概念，PE可能反映了P3B相关的动机意义的错误。我们的结论是，需要更多的研究来测试预测的各种PE的假设，更严格的调查的PE的神经发生器可能有助于更好地理解的神经认知过程中所涉及的错误监控。
We conducted a literature review to examine the functional significance of the error positivity (Pe), an error-related electrophysiological brain potential often observed in combination with the error negativity (Ne). The review revealed many dissociations between documented effects on the Ne and Pe, suggesting that these components reflect different aspects of error processing. We found little support for the proposed hypotheses that the Pe is associated with the affective processing of errors or with posterror behavioral adaptation. Some support was found for the hypothesis that the Pe reflects conscious recognition of an error. Finally, we discuss the notion that the Pe may reflect a P3b associated with the motivational significance of the error. We conclude that more research is needed to test predictions of the various Pe hypotheses, and that more rigorous investigation of the neural generators of the Pe may contribute to a better understanding of the neurocognitive processes involved in error monitoring.
