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.
