摘要

背景：注意力缺陷/多动障碍（ADHD）和阅读障碍（RD）经常同时存在。目的：本研究调查了多动症儿童（6-12 岁）对视觉刺激的事件相关电位（ERP）反应，重点研究了 N170 分量，该分量表示对视觉单词的快速、自动和专门处理：20名患有多动症的儿童和20名性别和年龄匹配的发育正常（TD）儿童进行了脑电图任务，并接受了多项单词阅读和与阅读相关的认知技能测试：结果表明：多动症儿童的早期汉字神经特化存在缺陷。与TD儿童相比，ADHD儿童右半球的粗调谐效应不明显，而ADHD组则不存在细调谐效应。此外，多动症儿童对汉字的早期神经特化与正字法加工能力和快速命名速度相关：N170的研究结果表明，多动症儿童对视觉文字的早期处理存在偏差，这表明他们的阅读困难可能源于这些障碍。此外，正字法处理和快速命名可能在多动症儿童的早期汉字特化过程中发挥着重要作用。

Early visual word processing in children with ADHD: An ERP study

Background

Attention-deficit/hyperactivity disorder (ADHD) and reading disability (RD) co-occur frequently. Although reading comprehension difficulties in children with ADHD have been well documented, early visual word processing remains unclear.

Aims

This study investigated event-related potential (ERP) responses to visual stimuli in children with ADHD (6–12 years) by focusing on the N170 component, which signifies rapid, automatic, and specialized processing of visual words.

Procedures

Twenty children with ADHD and twenty typically developing (TD) children matched for sex and age performed an EEG task and underwent several word reading and reading-related cognitive skills tests.

Results

The results revealed deficits in early neural specialization for Chinese characters among children with ADHD. The coarse-tuning effect in the right hemisphere was less pronounced in children with ADHD compared to TD children, and a fine-tuning effect was absent among the ADHD group. Moreover, the early neural specialization for Chinese characters in children with ADHD correlated with orthographic processing ability and rapid naming speed.

Conclusions and implications

The N170 findings indicate deviant early processing of visual words in children with ADHD, suggesting their reading difficulties may stem from these impairments. Furthermore, orthographic processing and rapid naming may play a vital role in the early specialization for Chinese characters among children with ADHD.

期刊介绍： Research In Developmental Disabilities is aimed at publishing original research of an interdisciplinary nature that has a direct bearing on the remediation of problems associated with developmental disabilities. Manuscripts will be solicited throughout the world. Articles will be primarily empirical studies, although an occasional position paper or review will be accepted. The aim of the journal will be to publish articles on all aspects of research with the developmentally disabled, with any methodologically sound approach being acceptable.
