The Essential Educator on Early Visual Language
Research, notes the education blog site, "The Essential Educator," has indicated that the language areas of the brain have no preference for language input and that the most accessible pathway for full access to linguistic information for many deaf children is through the visual channel.
A visual language, the "Essential Educator" notes, such as American Sign Language, is a natural language system, functions independently from spoken language, and has a fully developed grammatical system. Delay in acquiring a first language produces poorer over-all language performance, and without complete access to language during early development, it is difficult for deaf and hard of hearing children’s language acquisition to be on par with that of hearing children.
