奖励已被证明可以改善与注意缺陷多动障碍（ADHD）有关的行为和认知过程，但这些改善发生的信息处理机制仍不清楚。我们研究了基于表现的奖励对ADHD儿童和典型发展控制的主要任务刺激，错误和反馈处理相关的ERP的影响。参与者完成了一项侧翼任务，其中包含有和没有基于绩效的奖励的区块。ADHD儿童表现出与处理侧翼刺激（P3）和错误（ERN，Pe）相关的ERP振幅降低，但在反馈处理（FRN）方面没有差异。对于ADHD儿童，奖励在各组中类似地增强了侧翼相关的P3振幅，并且错误相关的Pe振幅存在差异。这些研究结果表明，奖励可以通过增强对相关刺激的处理和增加错误评估来改善ADHD儿童的认知缺陷。
Rewards have been shown to improve behavior and cognitive processes implicated in attention‐deficit hyperactivity disorder (ADHD), but the information‐processing mechanisms by which these improvements occur remain unclear. We examined the effect of performance‐based rewards on ERPs related to processing of the primary task stimuli, errors, and feedback in children with ADHD and typically developing controls. Participants completed a flanker task containing blocks with and without performance‐based rewards. Children with ADHD showed reduced amplitude of ERPs associated with processing of the flanker stimuli (P3) and errors (ERN, Pe), but did not differ in feedback‐processing (FRN). Rewards enhanced flanker‐related P3 amplitude similarly across groups and error‐related Pe amplitude differentially for children with ADHD. These findings suggest that rewards may improve cognitive deficits in children with ADHD through enhanced processing of relevant stimuli and increased error evaluation.
