Error-related negativity (ERN), an electroencephalogram (EEG) component following an erroneous response, has been associated with the subjective motivational relevance of error commission. A smaller EEG event, the correct response negativity (CRN), occurs after a correct response. It is unclear why correct behavior evokes a neural response similar to error commission. CRN might reflect suboptimal performance: in tasks where speed is motivationally relevant (i.e., incentivized), a correct but slow response may be experienced as a minor error. The literature is mixed on the relationship between CRN and response time (RT), possibly due to different motivational structures, tasks, or individual traits. We examined ERN and CRN in a go/no-go task where correctness and speed were encouraged using a points-based feedback system. A key individual trait, regulatory focus, describes a person's tendency to seek gains (promotion focus) and avoid losses (prevention focus). Trait regulatory focus was measured, and participants were randomly assigned to one of three conditions: points gain, points loss, and informative-only feedback. Participants committed too few errors to reliably model ERN effects. CRN amplitude related to RT in all feedback conditions, with slower responses having larger CRN. Participants with stronger promotion focus had a more exaggerated RT/CRN relationship in the point gain condition, suggesting that regulatory fit influences the motivational relevance of speed and thus the negative subjective experience and CRN for slower responses. These findings are consistent with the claim that CRN reflects RT when RT is motivationally relevant and that the CRN/RT relationship reflects the degree of subjective motivational relevance.

正确的反应消极性可能反映了速度奖励任务中监管配合下反应时间的主观价值


错误相关消极性（ERN）是错误反应后的脑电图（EEG）成分，与错误行为的主观动机相关性相关。较小的脑电图事件，即正确反应阴性（CRN），发生在正确反应之后。目前还不清楚为什么正确的行为会引起类似于犯错的神经反应。 CRN 可能反映次优性能：在速度与动机相关（即，激励）的任务中，正确但缓慢的响应可能会被视为小错误。关于 CRN 和响应时间 (RT) 之间关系的文献褒贬不一，这可能是由于不同的动机结构、任务或个人特征所致。我们在进行/不进行任务中检查了 ERN 和 CRN，其中使用基于点的反馈系统鼓励正确性和速度。一个关键的个人特征，即监管焦点，描述了一个人寻求收益（促进焦点）和避免损失（预防焦点）的倾向。对特质监管重点进行了测量，参与者被随机分配到以下三种情况之一：得分增加、得分损失和仅供参考的反馈。参与者犯的错误太少，无法可靠地模拟 ERN 效应。在所有反馈条件下，CRN 幅度与 RT 相关，响应越慢，CRN 越大。具有较强促销重点的参与者在得分条件下具有更夸张的 RT/CRN 关系，这表明监管契合度影响速度的动机相关性，从而影响较慢反应的负面主观体验和 CRN。这些发现与以下说法一致：当 RT 与动机相关时，CRN 反映 RT，并且 CRN/RT 关系反映主观动机相关程度。
