Abstract

The current study examined the executive function (EF) deficits and their roles in reading in one hundred and four Cantonese-speaking children with typical development, reading disabilities (RD), ADHD, and comorbid ADHD and RD (ADHD + RD). Children's EF and reading skills were measured. Analysis of variance results showed that all children with disorders manifested deficits in verbal and visuospatial short-term and working memory and behavioral inhibition. Moreover, children with ADHD and ADHD + RD also exhibited deficits in inhibition (IC and BI) and cognitive flexibility. These findings demonstrated that the EF deficits in Chinese children with RD, ADHD, and ADHD + RD are similar to those in their counterparts using alphabetic languages. However, children with ADHD + RD displayed more severe deficits in visuospatial working memory compared to children with RD and ADHD, which was inconsistent with that observed in children using alphabetic languages. Regression analysis results showed that verbal short-term memory was a significant predictor for both word reading and reading fluency in children with RD and ADHD + RD. Moreover, behavioral inhibition significantly predicted reading fluency in children with ADHD. These findings also agreed with previous studies. Collectively, the results of the current study showed that the EF deficits and their roles in reading found in Chinese children with RD, ADHD, and ADHD + RD are mainly consistent with children using alphabetic languages. However, more studies are still needed to confirm these findings, especially comparing the severity of working memory among these three disorders.

执行功能是注意力缺陷/多动障碍、阅读障碍以及合并注意力缺陷/多动障碍和阅读障碍的中国儿童单词阅读和阅读流畅性的基础。
本研究调查了 144 名患有典型发育障碍、阅读障碍(RD)、多动症(ADHD)以及合并有多动症和阅读障碍(ADHD + RD)的粤语儿童的执行功能(EF)缺陷及其在阅读中的作用。对儿童的EF和阅读技能进行了测量。方差分析结果显示,所有患有阅读障碍的儿童在言语和视觉空间短期记忆、工作记忆以及行为抑制方面都存在缺陷。此外,ADHD 和 ADHD + RD 儿童在抑制(IC 和 BI)和认知灵活性方面也表现出缺陷。这些研究结果表明,中国RD、ADHD和ADHD + RD儿童的EF缺陷与使用字母语言的儿童相似。然而,与RD和ADHD儿童相比,ADHD + RD儿童在视觉空间工作记忆方面表现出更严重的缺陷,这与在使用字母语言的儿童中观察到的情况不一致。回归分析结果显示,言语短时记忆对RD和ADHD + RD儿童的单词阅读和阅读流畅性有显著的预测作用。此外,行为抑制对多动症儿童的阅读流畅性也有明显的预测作用。这些研究结果也与之前的研究结果一致。总之,本研究结果表明,在中国RD、ADHD和ADHD+RD儿童中发现的EF缺陷及其在阅读中的作用主要与使用字母语言的儿童一致。然而,仍需要更多的研究来证实这些发现,尤其是比较这三种障碍儿童工作记忆的严重程度。

期刊介绍: The purposes of Child Neuropsychology are to: publish research on the neuropsychological effects of disorders which affect brain functioning in children and adolescents, publish research on the neuropsychological dimensions of development in childhood and adolescence and promote the integration of theory, method and research findings in child/developmental neuropsychology. The primary emphasis of Child Neuropsychology is to publish original empirical research. Theoretical and methodological papers and theoretically relevant case studies are welcome. Critical reviews of topics pertinent to child/developmental neuropsychology are encouraged. Emphases of interest include the following: information processing mechanisms; the impact of injury or disease on neuropsychological functioning; behavioral cognitive and pharmacological approaches to treatment/intervention; psychosocial correlates of neuropsychological dysfunction; definitive normative, reliability, and validity studies of psychometric and other procedures used in the neuropsychological assessment of children and adolescents. Articles on both normal and dysfunctional development that are relevant to the aforementioned dimensions are welcome. Multiple approaches (e.g., basic, applied, clinical) and multiple methodologies (e.g., cross-sectional, longitudinal, experimental, multivariate, correlational) are appropriate. Books, media, and software reviews will be published.
