The difference between the audiovisual incongruent condition and the audiovisual congruent condition is known as cross-modal conflict, which is an important behavioral index to measure the conflict control function. Previous studies have found conflict control deficits in children with attention-deficit/hyperactivity disorder (ADHD), but it is not clear whether and how cross-modal conflict occurs in children with ADHD at different processing levels. The current study adopted the cross-modal matching paradigm to recruit 25 children with ADHD (19 boys and 6 girls) and 24 TD children (17 boys and 7 girls), aiming to investigate the cross-modal conflict effect at the perception and response levels of children with ADHD. The results showed that both groups of children showed significant cross-modal conflict, and there was no significant difference between the ADHD and TD groups in the number of error trials and mean response time. However, the cross-modal conflict effect caused by auditory distractors was different between the ADHD and TD groups; the TD group had stronger auditory conflict at the response level, whereas the ADHD group had weaker auditory conflict. This indicates that the ADHD group had a deficit of auditory conflict at the response level.
视听不一致条件与视听一致条件之间的差异被称为跨模态冲突，这是衡量冲突控制功能的一个重要行为指标。先前的研究发现注意缺陷多动障碍（ADHD）儿童存在冲突控制缺陷，但尚不清楚ADHD儿童在不同加工水平上是否以及如何发生跨模态冲突。本研究采用跨模态匹配范式招募了25名ADHD儿童（19名男孩和6名女孩）和24名发育正常（TD）儿童（17名男孩和7名女孩），旨在研究ADHD儿童在感知和反应水平上的跨模态冲突效应。结果表明，两组儿童均表现出显著的跨模态冲突，ADHD组和TD组在错误试验次数和平均反应时间上无显著差异。然而，ADHD组和TD组由听觉干扰物引起的跨模态冲突效应不同；TD组在反应水平上有更强的听觉冲突，而ADHD组的听觉冲突较弱。这表明ADHD组在反应水平上存在听觉冲突缺陷。
