Developmental Language Disorder and the Assessment of Signed Language
In recent years, deaf and/or hard of hearing (D/HH) children with atypical signed language abilities have become the focus of attention by researchers and educators, especially clinicians in programs that focus on bilingual (signed-written/spoken) education. Studies have shown that Deaf children with a language disorder present with a myriad of linguistic challenges, including struggles with fingerspelling comprehension, complex morphology, or lexical processing. This chapter highlights methods commonly used in assessing children suspected of having a developmental signed language disorder. In addition, it outlines issues that are critical for working with D/HH children, such as considering the possible role of co-occurring disabilities (such as attention deficits and autism) and obtaining information and support from parents and educators/clinicians. Finally, the chapter outlines suggestions for researchers and clinicians working together to identify and provide intervention for children suspected of having a developmental signed language disorder.
