个人通常会评估他们的表现和获得的反馈是否匹配。以往的研究表明，反馈消极性（FN）取决于结果概率和反馈效价。然而，不太清楚的是，在何种程度上以前的影响结果概率FN依赖于自我评价的反应正确性。因此，我们研究了结果概率对FN振幅的影响，在一个简单的去/不去的任务，允许自我评价的反应正确性。我们还研究了绩效不相容性和反馈价的影响。在N = 22参与者的样本中，结果概率被操纵的手段precues，反馈效价通过金钱反馈，和性能不兼容的反馈，诱导匹配与不匹配的个人的表现。我们发现，100%的结果概率条件下诱导一个更负的FN以下没有损失比50%的结果概率条件。与100%结果概率条件相比，50%结果概率条件下丢失后的FN更负。性能不兼容的损失导致更负的FN比性能兼容的损失。结果表明，在研究结果概率和期望不匹配对FN的影响时，应考虑反应正确性的自我评价。
Individuals typically evaluate whether their performance and the obtained feedback match. Previous research has shown that feedback negativity (FN) depends on outcome probability and feedback valence. It is, however, less clear to what extent previous effects of outcome probability on FN depend on self-evaluations of response correctness. Therefore, we investigated the effects of outcome probability on FN amplitude in a simple go/no-go task that allowed for the self-evaluation of response correctness. We also investigated effects of performance incompatibility and feedback valence. In a sample of N = 22 participants, outcome probability was manipulated by means of precues, feedback valence by means of monetary feedback, and performance incompatibility by means of feedback that induced a match versus mismatch with individuals' performance. We found that the 100% outcome probability condition induced a more negative FN following no-loss than the 50% outcome probability condition. The FN following loss was more negative in the 50% compared to the 100% outcome probability condition. Performance-incompatible loss resulted in a more negative FN than performance-compatible loss. Our results indicate that the self-evaluation of the correctness of responses should be taken into account when the effects of outcome probability and expectation mismatch on FN are investigated.
