摘要: 反馈负波(feedback related negativity, FRN)是由代表行为错误或失去金钱等负性反馈刺激诱发的一种脑电波成分,出现在刺激呈现后250~300ms左右,偶极子源定位发现这一成分产生于前扣带回附近。对于FRN的功能意义的解释主要有强化学习理论和情绪动机假说,前者认为FRN反映的是神经系统对反馈刺激的认知加工过程,而后者认为FRN反映的是对情绪动机意义的评价过程。两种理论框架下还有一些目前研究仍待解决的问题,可能是未来研究的方向

Abstract: The feedback related negativity (FRN) is an ERP component elicited by feedback stimuli that indicate response errors or monetary losses. This component appeared at about 250-300ms interval after feedback onset and was shown to be generated in anterior cingulate cortex by resource analysis. There are two theories that account for the functional significance of FRN: the reinforcement learning theorists believe that FRN reflects the cognitive processing of the feedback stimulus, whereas the affective-motivational hypothesis argues that FRN mirrors the neural evaluation of emotional and motivational meaning in the feedback stimuli. Despite in-depth insights provided by previous studies into our understanding of FRN, there are still some important questions to be answered, which might be the direction of future studies

Key words: FRN, reinforcement learning theory, affective-motivational hypothesis, Anterior Cingulate Cortex, ERP
