Identifying Developmental Language Disorder in the Context of Dialect
The podcast episode discusses the importance of identifying developmental language disorder (DLD) within the context of a child's dialect. It emphasizes the need to distinguish between dialects and disorders and to avoid misidentifying children who speak a different dialect as having an impairment. The speaker shares her experience of studying African American English and Southern White English dialects in rural Louisiana and highlights the unique features and challenges associated with each dialect. The episode also mentions the use of language probes, such as the sentence recall task and past tense probe, which can assist in diagnosing DLD within specific dialects.
Understanding Dialects as Language Systems
The podcast explores the concept of dialects as unique language systems and emphasizes the importance of understanding and respecting each dialect's rules and variations. It highlights that dialects are products of healthy language development influenced by cultural norms and should not be viewed as deviations from general American English. The episode discusses different methods for studying dialects, including listener judgment, language sample analysis, and quantifying non-mainstream forms. It also addresses the need for clinicians to adopt a dialect-appropriate approach in their assessments and interventions.
Challenges in Identifying DLD in Dialect Speakers
The podcast delves into the challenges faced by clinicians in identifying developmental language disorder (DLD) in dialect speakers. It discusses the difficulty of distinguishing between dialect-appropriate forms and disorder-specific errors and emphasizes the need for a dialect-appropriate scoring system. The speaker shares insights from her research on dialect-specific markers, such as the use of past tense forms, and mentions the importance of considering positive family history when evaluating language difficulties in dialect speakers.
Implications for Clinical Practice and Future Research
The podcast concludes by discussing the practical implications of the disorder within dialect framework in clinical practice. It encourages clinicians to adopt a repertoire approach that supports and expands a child's language skills within their dialect while also promoting functional communication in academic settings. The episode highlights ongoing research on developing and validating language probes specific to dialects, which can aid in the diagnosis and intervention of developmental language disorder in dialect speakers.
