The role of personal responsibility in decision-making and its influence on the outcome evaluation process have been investigated relatively rarely in cognitive neuroscience. The present event-related brain potential (ERP) study manipulated the subjective sense of responsibility by modifying outcome controllability in a gambling task. Participants reported a higher sense of responsibility and produced a larger fERN when they were told that the game was 'controllable' compared with when they were told that the game was 'uncontrollable.' In addition, fERN amplitude was correlated with individual self-reports of personal responsibility over the outcomes. These results indicate that self-attribution of responsibility associated with different degrees of controllability affects the outcome evaluation process and fERN amplitude.
在认知神经科学中，个人责任感在决策中的作用及其对结果评估过程的影响相对较少受到研究关注。本事件相关脑电位（ERP）研究通过在赌博任务中改变结果可控性来操纵主观责任感。与被告知游戏“不可控”相比，当参与者被告知游戏“可控”时，他们报告的责任感更高，并且产生的 fERN 更大。此外，fERN 幅度与个人对结果的自我责任感报告相关。这些结果表明，与不同可控程度相关的自我归因责任感会影响结果评估过程和 fERN 幅度。
