反馈处理是学习的一个重要方面。在人脑中，通常通过测量与事件相关的电位（与反馈相关的负分量）来检查反馈处理。通常，通过直接比较随机试验中的增益和损失反馈来研究与反馈相关的消极成分；然而，这种方法不能控制与意外反馈相关的混淆。在本研究中，我们使用分块设计赌博任务来研究反馈相关的消极性对正反馈和负反馈的敏感性，分别获得和损失。虽然在损失域中似乎没有显着的与反馈相关的负面影响，但结果显示，与接收增益相比，在忽略增益期间与反馈相关的负面影响更大。这些发现进一步支持了奖励积极性假说，该假说宣称，与反馈相关的消极性与在收益而不是损失的情况下对结果的处理有关，无论意外情况如何。
Feedback processing is an important aspect of learning. In the human brain, feedback processing is often examined by measuring an event-related potential, the feedback-related negativity component. Typically, the feedback-related negativity component is investigated by directly comparing gain with loss feedback randomized across trials; however, this method does not control for confounds associated with unexpected feedback. For this study we used a blocked design gambling task to investigate the sensitivity of feedback-related negativity to positive and negative feedback separately for gains and losses. While there appeared to be no significant feedback-related negativity in the loss domain, results revealed an enlarged feedback-related negativity during the omission of gains compared to the reception of gains. These findings further support the reward positivity hypothesis which declares that the feedback-related negativity is associated with the processing of outcomes in the context of gains as opposed to losses, irrespective of unexpectedness.
