Narrative Microstructure and Macrostructure Skills of Persian-Speaking Children with Autism Spectrum Disorder

Area of Science:

• Developmental Psychology
• Linguistics
• Neurodevelopmental Disorders

Background:

• Narrative production skills in children with autism spectrum disorder (ASD) yield inconsistent findings.
• This study investigates if narrative deficits in ASD stem from underlying language difficulties.

Purpose of the Study:

• To compare narrative skills of children with ASD to chronological age-matched (CAM) and language-matched (LM) peers.
• To determine if language impairments, rather than ASD itself, explain narrative production differences.

Main Methods:

• Spoken narratives from 16 children with ASD, 16 CAM, and 16 LM peers were analyzed.
• Statistical analyses included Kruskal-Wallis and ANOVA to compare narrative variables (e.g., NTC, NSG, SI, NTW, ATL).

Main Results:

• Microstructure: Children with ASD showed similar productivity and syntactic complexity to LM peers, but lower than CAM peers.
• Macrostructure: Children with ASD scored significantly lower than both CAM and LM peers on story grammar elements and overall narrative structure (P < 0.001).

Conclusions:

• Narrative coherence and story grammar are more demanding for children with ASD than basic language productivity or syntactic complexity.
• Deficits in narrative macrostructure appear distinct from language impairments in children with ASD.
