Summary

Some children with developmental language disorders experience more disfluencies, linked to advanced vocabulary and age. These fluency issues may stem from language development or speaking capacity mismatches.

Area of Science:

  • Speech and Language Pathology
  • Developmental Psychology
  • Linguistics

Background:

  • Developmental language disorders (DLD) affect language acquisition in children.
  • Disfluencies, such as stuttering, can co-occur with DLD.
  • Understanding the relationship between DLD and disfluencies is crucial for intervention.

Purpose of the Study:

  • To investigate if a subset of children with DLD exhibit higher disfluency rates.
  • To explore if language deficits correlate with fluency differences in children with DLD.
  • To identify factors contributing to fluency breakdown in children with DLD.

Main Methods:

  • Analysis of spontaneous language samples from 60 preschool children with DLD.
  • Quantification of disfluency frequency and type.

  • Comparison of demographic, intelligence, and language variables between disfluent and non-disfluent groups.

    • Main Results:

    • A subset of 10 children showed significantly higher disfluency rates.
    • Children with more disfluencies were older and had higher vocabulary scores.
    • No significant differences were found in other language or intelligence measures.

    Conclusions:

    • Certain children with DLD are at higher risk for fluency issues.
    • Lexical and syntactic dyssynchronies or demand-capacity mismatches may underlie fluency breakdown.
    • Findings support neuropsycholinguistic and Demands and Capacities models of disfluency.
