All formal language is based on vision or hearing
From before birth we are all exposed – maybe bombarded is a better word – with auditory and visual information that we call “language”. It’s natural for us as adults to interact with and communicate with our children from the very first moments of life. Adults are often the primary carriers of this information and are the teachers of what we know as “language”. Each generation passes it along to the next.
In our culture, we tend to think of the developmental journey of learning language and communication in the context of “speaking and writing English” (or another language spoken in the home) or, if the person is deaf, we might consider American Sign Language (ASL). Language is passed down from one person to the next. Throughout the world, with all of our different cultures and languages, the process repeats itself. We learn language from people who are already fluent in that language. We are influenced by the culture that surrounds us. What happens though, if the person cannot perceive or access the language or cultural identifiers around them?
For the person who is deafblind, who has only ever accessed information tactually and perceives the world tactually, access to language that is meaningful is going to be very difficult. How can they learn tactile communication if there aren’t people around them who are already fluent in tactile communication? Does a formal tactile language truly exist? One that is not derived from concepts based on vision or hearing?
