Multisensory integration is a fundamental form of sensory processing that is involved in many everyday tasks. Those with Attention-Deficit/Hyperactivity Disorder (ADHD) have characteristic alterations to various brain regions that may influence multisensory processing. The overall aim of this work was to assess how adults with ADHD process audiovisual multisensory stimuli during a complex response time task. The paradigm used was a two-alternative forced-choice discrimination task paired with continuous 64-electrode electroencephalography, allowing for the measurement of response time and accuracy to auditory, visual, and audiovisual multisensory conditions. Analysis revealed that those with ADHD (n=10) respond faster than neurotypical controls (n=12) when presented with auditory, visual, and audiovisual multisensory conditions, while also having race model violation in early response latency quantiles. Adults with ADHD also had more prominent multisensory processing over parietal-occipital brain regions at early post-stimulus latencies, indicating that altered brain structure may have important outcomes for audiovisual multisensory processing. The present study is the first to assess how those with ADHD respond to multisensory conditions during a complex response time task, and demonstrates that adults with ADHD have unique multisensory processing when assessing both behavioral response time measures and neurological measures.

患有注意力缺陷/多动障碍的年轻人的视听多感官处理

多感觉整合是一种基本的感觉处理形式，涉及许多日常任务。那些患有注意力缺陷/多动障碍 (ADHD) 的人对可能影响多感官处理的各个大脑区域有特征性的改变。这项工作的总体目标是评估患有 ADHD 的成年人在复杂的响应时间任务中如何处理视听多感官刺激。使用的范式是与连续 64 电极脑电图配对的两种替代强制选择辨别任务，允许测量对听觉、视觉和视听多感官条件的响应时间和准确性。分析表明，当出现听觉、视觉和视听多感官条件时，患有 ADHD 的人（n=10）比神经典型的对照组（n=12）反应更快，同时在早期响应延迟分位数中也存在种族模型违规。在刺激后的早期潜伏期，患有 ADHD 的成年人在顶枕叶大脑区域也有更突出的多感觉处理，这表明改变的大脑结构可能对视听多感觉处理有重要的影响。本研究首次评估 ADHD 患者在复杂的响应时间任务中如何对多感觉条件做出反应，并证明 ADHD 成人在评估行为响应时间测量和神经系统测量时具有独特的多感觉处理。表明改变的大脑结构可能对视听多感官处理产生重要影响。本研究首次评估 ADHD 患者在复杂的响应时间任务中如何对多感觉条件做出反应，并证明 ADHD 成人在评估行为响应时间测量和神经系统测量时具有独特的多感觉处理。表明改变的大脑结构可能对视听多感官处理产生重要影响。本研究首次评估 ADHD 患者在复杂的响应时间任务中如何对多感觉条件做出反应，并证明 ADHD 成人在评估行为响应时间测量和神经系统测量时具有独特的多感觉处理。
