This chapter reviews research on the development of American Sign Language, mostly in deaf children with deaf parents. It examines what we know about early aspects of development, including babbling, phonological development, early lexical development, gestures and pointing. Morphological development is described for verb agreement, the acquisition of classifiers, and facial grammar. It reviews the development of syntax and spatial mapping. The development of manually-coded English (MCE) systems is also examined, including lexical, grammatical, and morphological development in young children with a hearing loss.
