本研究采用视觉搜索任务，对注意缺陷多动障碍(ADHD)和发育性阅读障碍(DD)共病儿童、单纯ADHD儿童和典型发育期儿童进行视觉搜索，以探讨ADHD和DD共病的发病机制。在任务过程中，参与者从每个实验中的五个角色中搜索目标角色。干扰因素包括拼写相似的字符、同音字、不相关的字符和不同颜色的字符(即红色)。结果显示，在所有类型的牵引器中，临床组的首次注视持续时间均长于对照组。与单纯ADHD儿童和健康对照组相比，ADHD合并DD儿童在凝视时长和总观看时间上也更容易受到红色特征的影响。讨论了共病(ADHD+DD)在发病机制中的意义。这些结果可能有助于ADHD合并DD的诊断和治疗。
In this study, a visual search task was conducted on children with comorbid attention deficit/hyperactivity disorder (ADHD) and developmental dyslexia (DD), children with pure ADHD, and typically developing children to explore the pathogenesis of comorbidity between ADHD and DD. Participants searched for the target character from five characters in each trial during the task. The distractors included orthographically similar characters, homophones, unrelated characters, and characters of a different color (i.e., red). Results showed that the clinical groups produced longer first fixation duration than the control group in all types of distractors. Children with ADHD comorbid DD were also more susceptible to characters with the distracting red color in gaze duration and total viewing time than were children with pure ADHD and healthy controls. The implication of comorbidity (ADHD + DD) on the pathogenesis was discussed. These results may be helpful for the diagnosis and treatment of ADHD with comorbid DD.
