Syntax in Spanish-speaking children with Williams syndrome

Area of Science:

• Linguistics
• Developmental Psychology
• Genetics

Background:

• Williams syndrome (WS) is a genetic disorder associated with cognitive and behavioral differences.
• Individuals with WS often exhibit unique language profiles, necessitating detailed investigation.

Purpose of the Study:

• To assess the syntactic skills of Spanish-speaking children with Williams syndrome.
• To compare their performance against typically developing children matched for chronological and verbal age.

Main Methods:

• Evaluation of syntactic areas including phrase structure, recursion, and bound anaphora.
• Comparison of children with WS to chronological age-matched (CA-TD) and verbal age-matched (VA-TD) typically developing peers.

Main Results:

• Children with WS performed significantly worse than CA-TD peers across all tasks.
• Performance of children with WS was similar to VA-TD peers, indicating age-related language development patterns.
• Deficits were pronounced in sentences with cross-serial dependencies, syntactic constraints, and knowledge of functional words like nonreflexive pronouns.

Conclusions:

• Syntactic skill deficits in children with WS are evident, particularly in complex grammatical structures.
• Findings suggest potential processing bottlenecks or computational constraints underlying these language impairments in Williams syndrome.
