Summary

Phonological disorder (PD) and specific language impairment (SLI) directly impact a child's ability to communicate and are among the most prevalent developmental disorders. The proposed experiments manipulate the complexity of treatment targets to identify the most efficacious treatment approaches for English- and Spanish-speaking children aged 3 to 6 years who present with these disorders. This research will reveal the nature of interactions between sound and structure in language for these children and will have significant implications for a unique approach to target selection when treating persistent phonological and grammatical difficulties in children with PD, SLI, or both.

Conditions

  • Language Development Disorders
  • Speech Sound Disorder

Interventions

BEHAVIORAL

Phonological treatment

The clinician will provide models, verbal and/or tactile cues, and/or conversational recasts of speech sound targets following the methodology of Gierut and colleagues. Up to 100 productions will be targeted per 1-hour session.

BEHAVIORAL

Morpheme treatment

The clinician will provide models, verbal and/or tactile cues, and/or conversational recasts of targeted morphemes following the methodology of Plante and colleagues. A minimum of 50 productions will be targeted per 1-hour session.
