决策后悔中作为与不作为效应的事件相关电位研究

ERP Study of Action and Inaction in Decision-Making Regret

为了对作为、不作为效应的神经机制进行更加全面的研究,对FRN情绪反应假设进行进一步探索,对作为、不作为后悔与FRN之间关系更进一步的了解,本研究拟从错误决策引发后悔的角度探讨可能与后悔具有关联的ERP波.本研究采用运气轮博弈范式对作为、不作为后悔进行研究,通过记录与分析给予个体的反馈刺激所诱发的ERPs,了解作为、不作为决策后悔下的ERPs.研究结果表明,决策结果的正确与错误显著影响了FRN、P300,但作为类别的ERPs却受到了决策结果的影响.当决策结果为正确的时候,作为类别在FRN和P300上并无差异;仅在决策结果为错误的情况下,作为类别在FRN和P300上才存在差异.简言之,作为、不作为效应对FRN和P300有影响.

As a more comprehensive study of the neural mechanisms of the action effect, further exploration of the FRN emotional reaction hypothesis, understanding the relationship between the action effect and FRN, this study is to he raised from the ERP wave which may be associated with regret. In this work, paradigm wheel-of-fortune was used to study the action effect. The study of ERPs in decision-making was by way of recording and analyzing ERPs induced by feedback stimuli. The author found out that the right and wrong of decision-making affected significantly FRN and P300. ERPs of action effect were influenced by the results of decision-making. When the results were right, there is no difference between action effect in FRN and P300. When the results were wrong, there were differences between them. In a word, action effect and inaction effect can influence both FRN and P300.
