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

What this Trial Is About

Researchers are exploring how difficulties with learning sequences of sounds and grammar are connected in children with developmental language disorder (DLD), also called specific language impairment. This study focuses on three types of language patterns—Single Feature, OR/Disjunction, and Family Resemblance/Prototype—and investigates how children with DLD, speech sound disorder (SSD), and typical development respond to these patterns. The goal is to better understand the underlying causes of DLD and improve early diagnosis and treatment options. The study also considers whether adding meaning cues can help children learn language patterns more effectively. The study involves children aged 4 to 8 who will be randomly assigned to different groups to test sensitivity to these phonological patterns and the effect of semantic category cues. Participants will practice naming new words that match or do not match these patterns while researchers measure how accurately and consistently they produce sounds. Groups include children with DLD (with or without SSD), children with SSD alone, and typically developing children. The study also evaluates whether semantic cues improve learning of challenging patterns. Children will complete extensive testing including language assessments, hearing and oral structure checks, and autism screening to confirm eligibility. During sessions, researchers will measure speech accuracy, variability in articulation and acoustics, and response to semantic cues. These measures help track how well children learn and generalize language patterns. The study lasts about 30 minutes per assessment and aims to provide insights that support new intervention strategies for children with DLD and related speech disorders.
