What do you understand by Deaf?

What Language do Deaf People think in? Deaf means the person who is unable to hear completely or partially by birth. In case, if one loses hearing capability after meeting an accident, he is not considered the target in this article.

There are more than 30 million children in the world who are suffering from hearing loss.

Chomsky LAD:

Noam Chomsky is a renowned linguist and gave a theory of LAD (language acquisition device) in 1960. He claimed that every inborn has a built-in organ in the brain that is responsible for language acquisition. Though the theory was criticized by many counterparts and critics.

Language of Deaf People to think:   

Normally, when an infant hears a sound from his mother, he relates sound to the object and saves it like an image in the mind. His speaking power seems on the foundation of what he hears. He associates the different sounds with the objects or concepts in the form of an image in his memory. Later he tries to convert that sound image into the form of words.

As deaf people are unable to hear, so they don’t make images of the words, rather they use their own sign language in the brain. They keep on making sign language in the brain and associate things, objects, or concepts to a separate sign language. This topic is studied under the domain of Semiotics.  

Kinesics is the Language of Deaf People:

Deaf people, if they are not blind, use kinesics and save all the gestures, emotions, body language, and facial expressions as input and make pictures or signs in their brain and set certain beliefs according to the situation they are coming across.

Weeping is the language when there is no language.

An inborn has no language, so he weeps for having a feed, then mother-infant di-ad works slowly and gradually. The brain works like a computer and saves images, impressions, and signs in the memory.

Interaction in the Society:  

When a deaf react whether he is an infant, he keeps on making his beliefs by receiving the response against his reaction. Then he thinks based on his beliefs and tries to make things favorable.

How does the brain of deaf people think?

It has been believed that there are certain portions in the brain that are responsible to receive and process the language. The temporal lobe and the left hemisphere are the visible part of the brain which are supposed as affected areas in case of deafness. Research shows that sounds, written language, and spoken language are monitored by the temporal lobe.

Translation of thoughts and concepts into words is a complex phenomenon of the brain and this function takes place in the left hemisphere of the brain. Unfortunately, if an inborn is deaf, these two areas of the brain affect badly but it does not mean that these two areas are non-functional. You can say that these two areas become non-functional for speech-language but not for sign language. Moreover, we can say that the in-born deaf uses sign language to think critically. They have their own beliefs which you can judge by their behavior in society.

A lot of experiments have been made to check the response of the brain during perception and production of sign language in auditory impaired persons that is quite similar in those who can hear sounds.
