Orthographic-phonological mapping impairments in Chinese children with developmental dyslexia: insights from an ERP investigation.
Ann Dyslexia
December 2024
Jiangsu Key Laboratory of Language and Cognitive Neuroscience, Xuzhou, China.
In the realm of logographic writing systems, such as Chinese characters, orthographic transparency fundamentally differs from alphabetic languages, posing unique challenges for individuals with developmental dyslexia (DD). This study employed event-related potentials (ERPs) and a masked priming paradigm to investigate how Chinese children with DD compared to typically developing (TD) children in their utilization of orthographic-phonological mapping rules during the processing of pseudocharacters. The findings revealed noteworthy distinctions between TD and DD children.

Department of Linguistics, The University of Kansas, Lawrence, Kansas, United States of America.
Article Synopsis
- The Phonological Mismatch Negativity (PMN) is a brain response indicating how the brain processes phonological (speech sound) information, particularly when there's a violation of expected phonemes.
- In a study, participants listened to three-syllable words and three-note tunes, focusing either on the language or music, and were tested for their reactions when the first sounds mismatched what they expected.
- Results showed the PMN only occurred with phoneme mismatches and not with musical mismatches, suggesting it might be specifically sensitive to language, but further investigation is needed to clarify its relationship with other brain responses like the N400.
Overreliance on Sublexical Phonological Processing in Visual Word Recognition for Third-Grade Mandarin-Speaking Dyslexic Children.
Dyslexia
February 2025
Jing Hengyi School of Education, Hangzhou Normal University, Hangzhou, China.
Article Synopsis
- Developmental dyslexic (DD) children face difficulties with sublexical orthographic, phonological, and semantic processing, affecting their ability to recognize words visually.
- A study involving 50 DD and 47 typically developing (TD) third graders assessed their responses to different types of pseudo characters related to semantic and phonetic factors.
- Results indicated that DD children rely more on phonetic processing compared to TD children, suggesting that sublexical phonological processing plays a significant role in how DD children recognize words.
Phonological Awareness and Word Decoding Skills in the Early Readers of Kannada.
Indian J Psychol Med
June 2024
Dept. of Audiology and Speech-Language Pathology, Kasturba Medical College Mangalore, Manipal Academy of Higher Education, Karnataka, Manipal, 576 104, India.
Background: Phonological awareness has been recognized as a significant predictor of word-decoding skills in alphabetical languages. These languages differ in phonology, orthography, and how they are mapped for word decoding. However, the literature has debated its role in orthographically consistent languages.

Philosophy and Social Science Laboratory of Reading and Development in Children and Adolescents (South China Normal University), Ministry of Education, 55 West of Zhongshan Avenue, 510631 Guangzhou, China.
Article Synopsis
- Previous research primarily focused on cognitive control in bilinguals but not on specific brain regions that process phonological information during language production.
- Using representational similarity analysis, the study examined phonological representations in both native and second languages within single and mixed-language contexts.
- Findings revealed that bilinguals show more brain activation and worse performance in mixed contexts, with dominant language (L1) phonological representations prominently found in language processing areas during L2 production, supporting the nonselective processing hypothesis.
