In order to achieve further insight into the comorbidity of reading disorder (RD) and attention deficit/hyperactivity disorder (ADHD), lexical processing and rapid naming were studied in RD and ADHD. The Dual Route Cascaded model postulates that lexical processing contains two parallel processes: lexical route processing and sublexical route processing. An orthographic decision task and a phonological decision task were used to measure lexical and sublexical route processing, respectively. In addition, a rapid naming task was used to compare 27 children with RD, 18 children with ADHD, 20 children with ADHD+RD, and 29 controls. RD and ADHD shared impairments in accuracy of orthographic and phonological decision making as well as in rapid naming, which suggest that RD and ADHD may be overlapping disorders that share deficits in both lexical route and sublexical route processing. RD was dissociated from ADHD by being slower in both orthographical and phonological decision making that indicates unique deficits in RD on lexical and sublexical speed.
为了进一步深入了解阅读障碍（RD）和注意缺陷多动障碍（ADHD）的共病现象，对 RD 和 ADHD 患者的词汇处理和快速命名能力进行了研究。双通路级联模型假定词汇处理包含两个平行的过程：词汇通路处理和亚词汇通路处理。使用正字法判断任务和语音判断任务分别测量词汇和亚词汇通路处理。此外，还比较了 27 名 RD 儿童、18 名 ADHD 儿童、20 名 ADHD+RD 儿童和 29 名对照组儿童。RD 和 ADHD 在正字法和语音判断任务的准确性以及快速命名方面都存在障碍，这表明 RD 和 ADHD 可能是重叠的障碍，在词汇通路和亚词汇通路处理方面都存在缺陷。RD 在正字法和语音判断任务中的速度较慢，这表明 RD 在词汇和亚词汇速度方面存在独特的缺陷，从而与 ADHD 区分开来。
