Those who were born completely deaf and only learned sign language, it is not surprising, they think in sign language. It’s amazing that those who were born completely deaf, but learn to speak through vocal training, will sometimes think not only about the particular sign that they know but sometimes they think in the voice language they studied, with their brains that come up, As the vocal language sounds. First of all, most deaf people think in sign language. Just as the “inner voice” of the listening person is felt in his voice, a completely deaf person sees or, more accurately, feels that they are signing in the head when they “speak” in their heads.

Brain Impact between Deafness and Blindness

sign languageFor those deaf people who are not completely deaf or are wearing devices to allow them to hear a few, they will often experience a more vocal language in their “inner voice” in proportion to how do deaf people think.
Interestingly, deafness is much more serious than blindness regarding the impact it can have on the brain. This is not because the brains of deaf people are different from people’s hearing, regarding mental abilities, etc. Rather, it is because of how holistic is the language of our brain. To be clear, “language” here refers not only to colloquial languages, but also to sign language. It is simply important that the brain has some form of language that it can fully understand, and can turn into an inner voice to guide the thought.

Brain Development and Learning Disabilities

How Do Deaf People ThinkHow do deaf people think and behave? Recent research has shown that language is an integral part of brain functions such as memory, abstract thinking and, excitingly, self-awareness. Language, as shown, is a “device driver,” so to speak, which controls the main “hardware” brain. Thus, deaf people who are not identified as such very young or who live in places where they can not be taught sign language will be largely disabled until they learn a structured language, although in reality there is nothing wrong with their brain. The problem is even more serious than it may seem at first glance because of how important language is in the early stages of brain development. Those completely deaf people who do not learn sign language until later in life often have learning disabilities that remain with them throughout their life, even after they eventually learned a particular sign language.
This is because of how holistic is the way our brains develop and function, which deaf people were once considered mentally retarded and incomprehensible. It can be seen that in this way it may seem that monitoring a person who can not communicate because of the absence of any language and lacks self-awareness. However, in recent history, until the 1970s, it was still believed that deaf people were somehow mentally retarded.

How could this be when they had different sign languages ​​and even vocal training so that their brains could develop and function properly? Well, the problem arose because in the 1880s it was decided that deaf people should not use sign language; Rather, they should be forced to use the spoken language almost exclusively. This seems reasonably reasonable on the surface, since deaf people are fully able to learn the spoken language, and this will allow them to more fully integrate into the world of hearing. The problem with this was only recently discovered, and indeed many of the negative consequences are only clear now.
