Summary

The broad aim of this clinical study is to assess the hypothesis that morphological and phonological deficits are linked by a broader deficit in sequential pattern learning. This hypothesis applies to learning in general, but is especially critical as an avenue for developing earlier assessments and more powerful interventions for children with developmental language disorder (DLD; also known as specific language impairment). Other populations, such as at-risk toddlers, may also benefit from this new approach.

Conditions

  • Developmental Language Disorder
  • Speech Sound Disorder
  • Specific Language Impairment

Interventions

OTHER

Sensitivity to phonological rules

Assess whether children with developmental language disorder (DLD) are sensitive to different phonological patterns that are predicted to align with development of morphosyntax or the lexicon; children with speech sound disorder (SSD) are not predicted to be sensitive to the same phonological patterns.

OTHER

Sensitivity to semantic category cues.

Assess whether all children, including those with DLD, show improved learning of OR rules when a semantic category cue is used.
