New treatment option for Developmental Language Disorder
Official title A Developmental Framework For Linking Phonological And Morpho-syntactic Sequential Pattern Rules In DLD: Production
ClinicalTrials.gov ID: NCT04558541
What this study is testing
- What it's testing
- 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).

Who can take part
Ages 4 to 8. Healthy volunteers may be eligible.
You may be able to join if
- Because clinical precision is required, 4- to 8-year-olds will complete a large test battery.
- All children (TD, DLD, DLD + SSD, SSD) will score above 75 on the Nonverbal Scale of the Kaufman Assessment Battery for Children (KABC-II), which is...
- Hearing will be within normal limits
- Oral structures will be within normal limits (Robbins \& Klee, 1987).
- The Childhood Autism Rating Scale (Schopler et al., 2010) and parent report, will be used to rule out autism. Children with DLD will meet standard...
You likely can't join if
- for all participants:
- Hearing impairment
- Intellectual impairment
- Autism
- Significant motor impairment. Typical participants will be excluded if they show: -Histories of developmental, speech, language, or hearing disorders.

- The Childhood Autism Rating Scale (Schopler et al., 2010) and parent report, will be used to rule out autism. Children with DLD will meet standard criteria.
- Children with DLD will score below the cutoff of 87 on the Structured Photographic Expressive Language Test-P2 (SPELT-P2; Dawson et al., 2005) that has demonstrated high diagnostic accuracy for DLD.
- Children with DLD will perform below 80% in their spontaneous production of finite verb morphemes.
- Performance on a nonword repetition task will also support DLD status. Scores below 70% for total phonemes correct across all nonword lengths are greater than 1 SD below the mean for typical children.
- Speech production skills will be measured via the Goldman-Fristoe Test of Articulation-3 (GFTA-3; Goldman \& Fristoe, 2015) and the inconsistency subtest of the Diagnostic Evaluation of Articulation and Phonology (DEAP...

- Because of the emphasis on English phonological and morpho-syntactic patterns, all participants will be monolingual English learners or report dominant exposure to English from infancy. Exposure to other languages will...
