电生理学研究利用事件相关脑电位来研究与环境反馈评估相关的神经过程。特别是，反馈相关负性(FRN)已被证明反映了对金钱损失的评估和对业绩的负反馈。我们进行了两个实验来检验FRN是否对负反馈的大小敏感。在这两个实验中，参与者都进行了简单的赌博任务，在这些任务中，他们可以在每一次试验中获得一系列潜在的结果。在两个实验中，相对于指示金钱收益的反馈，指示不奖励的反馈与FRN相关；然而，在这两个实验中，FRN的大小并不表现出对非奖励大小的敏感性。这些数据表明，FRN反映了基于好的和坏的结果的二进制分类对反馈的早期评估。这些数据是根据当代的FRN理论以及与情绪处理有关的评估过程来讨论的。(C)2005 Elsevier B.V.保留所有权利。
Electrophysiological studies have utilized event-related brain potentials to study neural processes related to the evaluation of environmental feedback. In particular, the feedback-related negativity (FRN) has been shown to reflect the evaluation of monetary losses and negative performance feedback. Two experiments were conducted to examine whether or not the FRN is sensitive to the magnitude of negative feedback. In both experiments, participants performed simple gambling tasks in which they could receive a range of potential outcomes on each trial. Relative to feedback indicating monetary gain, feedback indicating non-rewards was associated with a FRN in both experiments; however, the magnitude of the FRN did not demonstrate sensitivity to the magnitude of non-reward in either experiment. These data suggest that the FRN reflects the early appraisal of feedback based on a binary classification of good versus bad outcomes. These data are discussed in terms of contemporary theories of the FRN, as well as appraisal processes implicated in emotional processing. (c) 2005 Elsevier B.V. All rights reserved.
