The aim of the present study was to examine the relationship between response inhibition and working memory in 8-12-year-old children with attention-deficit/hyperactivity disorder (ADHD; n = 19), reading disorder (RD; n = 17), ADHD + RD (n = 21), and control children (n = 19). For the first time a within-task methodology was used to study the combined effect of both executive functions on a common measure of task performance in two often comorbid childhood disorders, ADHD and RD. We found evidence of an interaction between both domains, suggesting that they rely on a common pool of resources. In addition, we found that children with ADHD or RD were not more seriously affected by the combined load of both executive functions than children without ADHD or RD.
本研究旨在探讨 8-12 岁患有注意力缺陷多动障碍（ADHD；n=19）、阅读障碍（RD；n=17）、ADHD+RD（n=21）和对照组儿童（n=19）的个体反应抑制与工作记忆之间的关系。本研究首次使用一种任务内方法研究了两种常见的儿童共患病（ADHD 和 RD）中两种执行功能的综合效应对任务表现的共同影响。我们发现这两个领域之间存在相互作用的证据，表明它们依赖于共同的资源池。此外，我们发现，与没有 ADHD 或 RD 的儿童相比，患有 ADHD 或 RD 的儿童并没有受到两种执行功能综合负荷的更严重影响。
