DOES BEING DEAF OR BLIND
ENHANCE THE OPPOSITE SENSE?
HYPOTHESIS

I think that being deaf or blind can enhance the opposite sense because of the dependency of other senses from the loss of one.

In the Nature Neuroscience October 12, Edition, there was a neurological study of cats that were born deaf. The researchers found that brain regions that normally assisted in hearing were taken over and used to enhance their vision instead.

A columnist Rich Maloof did research that confirmed that deaf people have better peripheral vision then someone who has perfect vision. Deaf people use their peripheral vision more than anything. They have enhanced peripheral vision by detecting objects in slow motion.

Full deafness correlates with the enhancement of the ability to perceive moving objects, which increases peripheral vision in the retina in our eye. Your retina is the light sensitive layer of the back of your eyeball that covers over half of the interior surface. Their retina also increases their visual attention to the point where it’s no longer advantageous, or the increase of the chances of effectiveness.

Deaf people’s brains will repurpose areas for hearing and allows for more intelligent perception.

A Canadian research team from the University of Montreal’s Auditory Neuroscience Laboratory studied that blind people are better at localizing sound that a seeing person. One of their studies showed that blindness actually might improve their ability to differentiate sound frequencies.

Their brain can interpret auditory signals that come from different people or different instruments. People who are blind can identify harmonicity, which is the harmonic relation between sounds. Harmonicity is one of the most powerful things involved in interpreting auditory surroundings.

Exposure to harmonic tones, with layers of harmonicity helps people who are blind to hear the harmonic tone more clearly.

A study was done where they blindfolded some people and kept some people non-blindfolded. They did a hearing test and the blindfolded people performed better than the non-blindfolded participants.

The blindfolded participants heard the harmonicity of the single tones better and clearer than the participants who weren’t blindfolded due to their sense being taken away.

CONCLUSION

My conclusion would be that both deaf and blind people's opposite senses are enhanced due to the harmonicity and their peripheral vision. For deaf people, their peripheral vision is exceedingly enhanced. For blind people, their auditory signals are improved by the harmonicity of single harmonic tones.
