患有ADHD的儿童患上阅读障碍(RD)的风险很高，尽管原因尚不清楚。ADHD相关的损害，包括处理速度，可能会使共发生的RD诊断的临床评估复杂化。我们提出了一种新的测量方法来(I)评估阅读发展和(Ii)提供一种分类读者的替代方法，这可能有助于研究ADHD的RD的病因。具体地说，由于语音解码和单词识别技能都是阅读流利性的重要前兆，我们提出了一种新的量化方法，在考虑了感知、运动反应或处理速度的差异后，对这两种技能进行了比较。40名男孩(14名对照组，15名ADHD，11名ADHD/+RD)完成了一项词汇判断任务，测试解码，另一项评估单词识别。使用漂移扩散方法对反应时间数据进行建模，以估计潜在的阅读技能。使用这些阅读技能估计，我们计算了小说阅读倾向指数，并将参与者分为三个阅读组(解码者、平衡读者和视听者)。这些群体的阅读和认知表现与理论预测一致，并为小说阅读倾向指数分类提供了外部效度。我们的发现展示了一种潜在的基于个人发展的阅读倾向的读者分类工具。
Children with ADHD are at high risk of developing a Reading Disability (RD), though the reasons remain unclear. ADHD-associated impairments, including processing speed, can complicate clinical evaluation for a co-occurring RD diagnosis. We propose a novel metric to (i) assess reading development and (ii) provide an alternative method to classifying readers that may aid investigations for etiologies of RD in ADHD. Specifically, as both phonological decoding and word recognition skills are important precursors of reading fluency, we propose a new quantitative method comparing these skills after accounting for variations in perception, motor response, or processing speeds. Forty boys (14 control, 15 ADHD, 11 ADHD/+RD) completed a lexical decision task testing decoding and another assessing word recognition. Response time data was modeled using a Drift Diffusion approach to estimate the underlying reading skills. Using these reading skill estimates, we calculated a novel Reading Tendency Index and classified participants into three reading groups (Decoders, Balanced Readers, and Sight Readers). The reading and cognitive performance of these groups were consistent with theoretical predictions and subsequently provided external validity for the novel Reading Tendency Index classification. Our findings demonstrate a potential classification tool for readers based on individual’s developed, reading tendencies.
