A Developmental Study of Lexico‐Phonological Distance in Vocabulary Learning: Evidence From Typically Developing and Learning‐Disabled Arabic‐Speaking Children
Developmental study examines vocabulary acquisition challenges in typically developing and learning-disabled Arabic-speaking children, highlighting phonological processing issues.
Key Points
This study investigates how lexico-phonological distance affects vocabulary learning in Arabic among children with and without learning disabilities.
Examined 299 Arabic-speaking children from Grades 1-6, including those with learning disabilities.
Analyzed performance across receptive and expressive vocabulary tasks based on word type.
Evaluated the interaction of group performance (typically developing vs. learning-disabled) with word type.
Children performed best on identical words and worst on unique words, with cognates in between.
The vocabulary gap increased for unique words among learning-disabled children, indicating difficulties in phonological processing.
Expressive vocabulary tasks were more affected by lexico-phonological distance compared to receptive vocabulary.
