Performance in decoding and writing of children with Developmental Language Disorder: preliminary data

Area of Science:

• Child language development
• Neurodevelopmental disorders
• Written language acquisition

Background:

• Developmental Language Disorder (DLD) affects language skills crucial for academic success.
• Understanding DLD's impact on literacy is vital for targeted interventions.
• Written language acquisition involves complex decoding and spelling processes.

Purpose of the Study:

• To assess the decoding and writing performance in children with DLD.
• To identify specific manifestations of DLD in written language tasks.
• To elucidate the process of written language acquisition in DLD.

Main Methods:

• Comparative study involving 80 children (16 with DLD, 64 controls).
• Evaluated word and pseudoword decoding speed and accuracy.
• Analyzed spelling errors in the DLD group.

Main Results:

• Children with DLD demonstrated significantly longer decoding times.
• The DLD group exhibited a lower percentage of correct answers in decoding.
• Arbitrary spelling errors were predominant in children with DLD.

Conclusions:

• Children with DLD face challenges in decoding speed and accuracy compared to peers.
• DLD is associated with specific patterns of spelling errors, particularly in natural orthography.
• Findings underscore the need for specialized support in literacy for children with DLD.
