We examine whether math anxiety is related to altered response monitoring in an arithmetic task. Response-locked event-related brain potentials (ERPs) were evaluated in 23 highly (HMA) and 23 low math-anxious (LMA) individuals while they performed an arithmetic verification task. We focused on two widely studied ERPs elicited during error processing: error-related negativity (ERN) and error positivity (Pe). Correct-related negativity (CRN), an ERP elicited after a correct response, was also studied. The expected ERN following errors was found, but groups did not differ in its amplitude. Importantly, LMA individuals showed less negative CRN and more positive Pe amplitudes than their more anxious peers, suggesting more certainty regarding response accuracy and better adaptive behavioral adjustment after committing errors in an arithmetic task in the LMA group. The worse control over response performance and less awareness of correct responses in the HMA group might reduce their ability to 'learn from errors'.
我们研究了数学焦虑是否与算术任务中反应监测的改变有关。在23名高数学焦虑（HMA）个体和23名低数学焦虑（LMA）个体执行算术验证任务时，对反应锁定的事件相关脑电位（ERP）进行了评估。我们重点关注在错误处理过程中诱发的两种广泛研究的ERP：错误相关负波（ERN）和错误正波（Pe）。还研究了正确反应后诱发的ERP——正确相关负波（CRN）。发现了错误后预期的ERN，但两组在其波幅上没有差异。重要的是，与焦虑程度较高的同龄人相比，LMA个体的CRN负波较小，Pe波幅更正，这表明LMA组在算术任务中犯错后对反应准确性更有把握，且行为适应性调整更好。HMA组对反应表现的控制较差，对正确反应的意识较低，这可能会降低他们“从错误中学习”的能力。
