A Cross-Sectional Study on Narrative Microstructure in Tamil-Speaking Autistic and Non-Autistic Children.

Area of Science:

• Developmental Psychology
• Linguistics
• Neurodevelopmental Disorders

Background:

• Narrative skills are crucial for decontextualized language use and cognitive development.
• Autistic children often exhibit atypical language development and communication patterns.
• Understanding narrative microstructure aids in assessing language abilities in autistic children.

Purpose of the Study:

• To examine narrative microstructure in Tamil-speaking autistic children and their neurotypical peers.
• To compare narrative abilities between language-level-matched autistic and non-autistic children aged 3-5 years.
• To identify specific linguistic challenges in autistic children's narrative skills.

Main Methods:

• A cross-sectional study involving 38 Tamil-speaking children (3-5 years old) with and without autism.
• Language level matching using standardized tests.
• Analysis of six narrative microstructure parameters (TNW, TNU, MLU-W, MLU-M, NDW, TTR) from story retelling and generation tasks.

Main Results:

• Autistic children consistently scored lower on all narrative microstructure parameters.
• Difficulties in language fluency and the use of shorter, simpler sentences were observed in autistic children.
• Significant differences in narrative complexity were found between the two groups.

Conclusions:

• Narrative assessment is vital for understanding language development in autistic children.
• The findings highlight specific areas of linguistic difficulty in autistic children's narrative skills.
• This research supports targeted interventions to improve narrative abilities in autistic populations.
