Word Learning in Arabic Diglossia in Children With Typical Language Development and Developmental Language Disorder

Area of Science:

• Linguistics
• Developmental Psychology
• Speech and Language Pathology

Background:

• Word learning relies on phonological and semantic representations.
• Phonological distance from a child's native dialect influences word processing.
• Arabic diglossia presents unique challenges for child language acquisition.

Purpose of the Study:

• Investigate the impact of phonological distance of Modern Standard Arabic (StA) words on word learning in Arabic diglossia.
• Compare word learning in children with typical language development (TLD) and developmental language disorder (DLD).
• Examine if phonological distance affects children with DLD more than those with TLD.

Main Methods:

• Tested 100 children (TLD and DLD) in kindergarten and first grade.
• Utilized word-learning probes with nonwords varying in phonological distance from Spoken Arabic (SpA).
• Compared learning of nonwords with only SpA phonemes versus those including unique StA consonants.

Main Results:

• Children with TLD demonstrated higher word learning scores than those with DLD.
• All children showed lower performance with phonologically distant words.
• An interaction revealed phonological distance hindered TLD children in kindergarten but DLD children in first grade.

Conclusions:

• Phonological distance is a key factor in word learning complexity within Arabic diglossia.
• The effect of phonological distance is multifaceted, interacting with modality, aptitude, and grade level.
• Findings have significant theoretical and clinical implications for understanding child word acquisition.
