本研究的目的是研究工作记忆的执行处理的本质，作为注意缺陷多动障碍（ADHD）的核心缺陷，与阅读障碍（RD）相关的缺陷不同。这包括检查语音回路和中央执行的工作记忆过程（Baddeley, 1986），作为区分ADHD和RD的潜在手段。参与者是16名ADHD/RD、16名RD和16名正常对照儿童，他们的性别、年龄和智商相匹配，他们执行的任务利用语音回路功能，语音回路和中央执行功能的组合，以及依赖中央执行功能的任务。分析显示，随着中央执行系统参与任务的增加，ADHD/RD儿童的表现比其他组更差。这是关于控制信息处理、修改和容纳新投入和监督能力的措施。这些发现反映了中央执行在工作记忆中的潜在效用，有助于理解ADHD患者执行处理缺陷的本质。他们还支持这些任务在区分ADHD和RD方面的有效性。
The aim of the current study was to examine the nature of executive processing in working memory as a core deficit in attention deficit hyperactivity disorder (ADHD) as distinct from deficits associated with reading disability (RD). This involved examination of the working memory processes of the phonological loop and central executive (Baddeley, 1986) as a potential means of differentiating ADHD from RD. The participants were 16 ADHD/RD, 16 RD and 16 normal control children, matched for sex, age and IQ, who performed tasks tapping phonological loop function, a combination of phonological loop and central executive functioning, and tasks relying on central executive functioning. Analysis revealed that as the involvement of the central executive in tasks increased, ADHD/RD children performed worse than the other groups. This was on measures of controlled information processing, modifying and accommodating new input and supervisory capacity. These findings reflect the potential utility of the central executive in working memory in understanding the nature of executive processing deficits in ADHD. They also support the efficacy of these tasks in discriminating ADHD from RD.
