Study 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.
Primary Outcome
The Treatment Probe is made of the selected treatment stimuli (words) that are consistent with the child's assigned experimental condition, and evaluates production accuracy of the treatment target within the verb stimuli. The treatment targets in these words have a consonant singleton or consonant cluster ("tee" vs. "tree", "sees" vs. "seats"), and are mono- or bi-morphemic contexts ("tease" vs. "sees"). Children are asked to pronounce each word following presentation of a corresponding picture
Interventions
- BEHAVIORAL Phonological treatment
- BEHAVIORAL Morpheme treatment
