This study examines changes in the error-related negativity (ERN/Ne) related to motivational incentives and personality traits. ERPs were gathered while adults completed a four-choice letter task during four motivational conditions. Monetary incentives for finger and hand accuracy were altered across motivation conditions to either be equal or favor one type of accuracy over the other in a 3:1 ratio. Larger ERN/Ne amplitudes were predicted with increased incentives, with personality moderating this effect. Results were as expected: Individuals higher on conscientiousness displayed smaller motivation-related changes in the ERN/Ne. Similarly, those low on neuroticism had smaller effects, with the effect of Conscientiousness absent after accounting for Neuroticism. These results emphasize an emotional/evaluative function for the ERN/Ne, and suggest that the ability to selectively invest in error monitoring is moderated by underlying personality.
本研究考察了与动机激励和人格特质相关的错误相关负波（ERN/Ne）的变化。在四种动机条件下，成年人完成一项四选一字母任务时收集了事件相关电位（ERP）。在不同动机条件下，对手指和手部准确性的金钱激励会有所改变，要么相等，要么以3:1的比例偏向一种准确性。预计随着激励增加，ERN/Ne波幅会增大，人格会调节这种效应。结果符合预期：尽责性较高的个体在ERN/Ne中与动机相关的变化较小。同样，神经质得分较低的个体影响较小，在考虑神经质因素后，尽责性的影响消失。这些结果强调了ERN/Ne的情绪/评估功能，并表明选择性投入错误监测的能力受到潜在人格的调节。
