Communication breakdowns in normal and language learning-disabled children's conversation and narration.

Summary

Language learning-disabled (LLD) children experience more speech disruptions during narration than conversation. Longer speech units correlate with more breakdowns for all children, especially LLD children.

Area of Science:

  • Speech-Language Pathology
  • Developmental Psychology
  • Linguistics

Background:

  • Communication breakdowns are common in children's speech.
  • Understanding these breakdowns in language learning-disabled (LLD) children is crucial for intervention.
  • Previous research has not fully explored task-specific differences in LLD children's communication breakdowns.

Purpose of the Study:

  • To investigate the frequency and types of communication breakdowns in LLD children.
  • To compare breakdown rates in conversational versus narrative speech tasks.
  • To examine the relationship between communication unit length and breakdowns in LLD children.

Main Methods:

  • Studied 7 LLD children (aged 9:10-11:1) and 14 typically developing peers.
  • Collected speech samples during conversation and narration tasks.

  • Analyzed communication breakdowns (stalls, repairs, abandoned utterances) and mean length of communication unit.

    • Main Results:

    • LLD children showed significantly more communication breakdowns per unit in narration than conversation.
    • Mean length of communication unit was also greater in narration for LLD children.
    • Longer communication units were associated with more breakdowns across all groups and tasks.

    Conclusions:

    • Narrative tasks may elicit more dysfluencies in LLD children's speech compared to conversational tasks.
    • Communication unit length is a factor influencing breakdown frequency.
    • Task demands and utterance length likely contribute to increased speech disfluencies in LLD children.
