DLD is hidden and affects approximately 2 children in every classroom.
The University at Buffalo Language Learning Lab, directed by Dr. Hendricks, is dedicated to research and instruction to better understand language learning among school-age children. Our goal is to improve the identification and treatment of DLD in order to improve outcomes for this critical population.
Developmental Language Disorder (DLD) is a lifelong condition where a person has persistent difficulty using and/or understanding spoken and written language. These challenges aren't explained by any causes such as hearing loss or autism, and DLD is generally considered a 'hidden condition,' as the signs aren't always obvious. Children with DLD have difficulty with talking or understanding language and it can also impact academic performance and social well-being. Fortunately, with the right support, children with DLD can still do well at school--both with their learning and with making friends.
Consequences of untreated DLD include lower educational outcomes (Catts et al., 2002), increased risk for unemployment (Conti-Ramsden & Durkin, 2012), and increased risk for anxiety and depression (Conti-Ramsden & Botting, 2008).
As many as 70% of school-age children with language disorders--including DLD--are not identified or given services to address their difficulties with language comprehension and production (Adlof et al., 2017; Tomblin et al., 1997).
Diagnosis of DLD among children who speak Non-Mainstream American English (NMAE) dialects is particularly problematic, and both under-identification (Seymour, Bland-Stewart, & Green, 1998) and over-identification (Morgan et al., 2015, 2016) are common. These misdiagnoses create a serious problem of potentially misallocated treatment resources. Children who are over-identified utilize clinician resources and may waste time completing unnecessary intervention activities. Further, misdiagnosing language variation as disordered may contribute to the social stigma against the use of NMAE dialects. Children who are under-identified do not receive interventions that would improve their academic progress.
