越来越多的人对使用脑电图，特别是事件相关脑电位（ERP）方法来研究人类的奖励过程感兴趣。自从发现反馈相关的消极性（Miltner等人，1997）以及将反馈相关的消极性和最近的奖励积极性与强化学习、中脑多巴胺功能和前扣带皮层（即，Holroyd和Coles，2002）研究人员使用ERP方法来探索人类奖励学习的神经基础。然而，如果不了解在使用企业资源规划和审查这些企业资源规划组成部分时必须考虑到的一些关键方法问题，就不能审查与反馈有关的消极因素和积极的奖励因素。例如，即使是组件名称-反馈相关的消极性-也是研究界争论的来源，因为有些人现在强烈认为该组件应该被命名为奖励积极性（Proudfit，2015）。在这里，10个关键的方法论问题进行了讨论-混淆组件命名，奖励积极性，组件识别，峰值量化和使用不同的波形，频率（N200）和组件污染（P300），反馈时间的影响，行动和任务的可学习性，以及如何学习的结果在反馈相关的负/奖励积极性的幅度变化。这里的希望是不提供一个确定的方法来检查反馈相关的消极/奖励积极性，而是概述了关键问题，必须考虑到当检查这个组件，以帮助研究人员在他们的研究与ERP方法的人类奖励处理。
There is growing interest in using electroencephalography and specifically the event-related brain potential (ERP) methodology to study human reward processing. Since the discovery of the feedback related negativity (Miltner et al., 1997) and the development of theories associating the feedback related negativity and more recently the reward positivity with reinforcement learning, midbrain dopamine function, and the anterior cingulate cortex (i.e., Holroyd and Coles, 2002) researchers have used the ERP methodology to probe the neural basis of reward learning in humans. However, examination of the feedback related negativity and the reward positivity cannot be done without an understanding of some key methodological issues that must be taken into account when using ERPs and examining these ERP components. For example, even the component name - the feedback related negativity - is a source of debate within the research community as some now strongly feel that the component should be named the reward positivity (Proudfit, 2015). Here, ten key methodological issues are discussed - confusion in component naming, the reward positivity, component identification, peak quantification and the use of difference waveforms, frequency (the N200) and component contamination (the P300), the impact of feedback timing, action, and task learnability, and how learning results in changes in the amplitude of the feedback-related negativity/reward positivity. The hope here is to not provide a definitive approach for examining the feedback related negativity/reward positivity, but instead to outline the key issues that must be taken into account when examining this component to assist researchers in their study of human reward processing with the ERP methodology.
