Grammatical morpheme analysis can accurately identify children with specific language impairment (SLI). The verb morpheme composite shows high sensitivity and specificity, suggesting its potential as a clinical marker for SLI.

Area of Science:

  • Linguistics
  • Developmental Psychology
  • Speech-Language Pathology

Background:

  • Specific language impairment (SLI) affects grammatical morpheme production in preschool children.
  • Accurate classification of SLI is crucial for timely intervention.
  • Existing diagnostic tools may benefit from refined linguistic markers.

Purpose of the Study:

  • To determine if grammatical morpheme production can classify preschool children with SLI.
  • To evaluate the diagnostic utility of specific morpheme composites and mean length of utterance (MLU).
  • To identify potential clinical markers for SLI.

Main Methods:

  • Discriminant function analysis was used to classify children.
  • Three variables were analyzed: finite verb morpheme composite, noun morpheme composite, and MLU in morphemes.

  • The study included preschool-age children with SLI and typically developing controls across two samples.

    • Main Results:

    • Discriminant analysis achieved high accuracy in distinguishing children with SLI from controls.
    • The verb morpheme composite demonstrated high sensitivity (>85%) and perfect specificity (100%).
    • Classification accuracy varied slightly across the three variables.

    Conclusions:

    • Grammatical morpheme production, particularly verb morphology, is a promising indicator for classifying SLI in preschoolers.
    • The verb morpheme composite shows potential as a reliable clinical marker for SLI.
    • These findings support the continued relevance of verb morphology deficits in SLI into school-age years.
