Chinese reading comprehension relies on multiple factors, with morphological awareness and reading fluency being particularly critical, especially for children with dyslexia. Phonological awareness also plays a key role in reading comprehension; however, its specific contribution to Chinese-speaking children with dyslexia remains a subject of debate. This study investigates the differential roles of phonological awareness in children with potential reading disabilities and their typically developing peers when learning Chinese. We utilized functional near-infrared spectroscopy (fNIRS) to examine key differences in the neural mechanisms underlying phonological awareness between two groups. Thirty Chinese-speaking children participated, including eighteen typically developing children (mean age = 9.97 years; average Chinese character recognition percentile = 90.42) and twelve children with potential reading disabilities (mean age = 8.47 years; average Chinese character recognition percentile = 60.00). Neural activation patterns during a Chinese phonological awareness task were compared between these two groups. The findings revealed that typically developing children tended to engage more right-hemispheric brain regions during Chinese phonological awareness tasks, including the right superior temporal gyrus (STG) and dorsal inferior frontal gyrus. In contrast, children with potential reading disabilities showed a greater reliance on left-hemispheric brain regions, such as the left STG and inferior parietal lobe. Moreover, typically developing children were more inclined to activate right-hemispheric regions relative to their counterparts in Chinese. These findings reveal distinct roles of phonological awareness in children with different reading abilities and highlight the significant association between right-hemispheric activation and phonological awareness in Chinese during early-stage language development.
