A Developmental Framework For Linking Phonological And Morpho-syntactic Sequential Pattern Rules In DLD: Production

This study investigates how children with Developmental Language Disorder (DLD) — a condition where children struggle with learning language despite normal intelligence and hearing — process and produce the sound and grammar patterns of English. Some children with DLD also have speech sound disorders (SSD). The research aims to understand how these two language systems interact in development so that more effective therapies can be designed. The study involves children aged 4 to 8 who may have typical development (TD), DLD, DLD with a speech sound disorder, or an isolated speech sound disorder. All children must have normal intelligence, normal hearing, no autism, and speak primarily English. You may be eligible if: - Your child is between 4 and 8 years old - Your child has normal hearing and oral structures - Your child scores above 75 on a non-verbal IQ test - Your child does not have autism - Your child is a monolingual English speaker or dominant English speaker from infancy You may NOT be eligible if: - Your child has a hearing impairment - Your child has an intellectual disability - Your child has autism - Your child has a significant motor impairment - Your child (if in the typical development group) has any history of speech, language, or hearing disorders Talk to your doctor to see if this trial is right for you.
