摘　　要：晚正成分能够反映不同效价和不同唤醒度的情绪。作为后悔的一种现象,作为效应是否与晚正成分具有关联是研究关心的问题。采用运气轮博弈的范式,记录与分析被试在"做"与"不做"决策下的ERPs。研究发现,决策结果的正误显著影响了FRN、P300和LPC的波幅大小。作为类别对FRN、P300和LPC波幅的影响受到不同决策结果的影响,在决策正确的条件下,作为类别对FRN、P300和LPC波幅不产生影响,而在决策错误的条件下,作为类别对FRN、P300和LPC波幅产生了显著的影响。结果表明作为效应不仅影响了FRN、P300的波幅,同时也影响了LPC的波幅,将来研究应进一步探明晚正成分与后悔的密切关联。Late positive component （LPC）can reflect emotion on different valence and different arouse. As a phenomenon of regret emotion, whether action effect is related with LPC is our interest. Using wheel - of - fortune paradigm, recording and analyzing the ERPs under the condition of actions and inactions, our research found out that correct decision - makings were significant different with error decision - making on the amplitude of FRN, P300 and LPC. The effect of action effect on the amplitude of FRN, P300 and LPC was impacted by the outcomes of decision - making. Under the condition of correct decision making,the action effect did not influence the am- plitude of FRN, P300 and LPC. Meanwhile, under the condition of error decision making, the action effect did influence the amplitude of FRN,P300 and LPC. These results indicated that action effect was indeed related with LPC. In the future, the study should further explore the relation between LPC and regret.
