Do blind people have a more sensitive sense of hearing and touch?

Summary: The brains of those who are born blind make new connections in the absence of visual information, resulting in enhanced, compensatory abilities such as a heightened sense of hearing, smell and touch, as well as cognitive functions (such as memory and language) according to a new study.

Why are the sense of touch and smell highly developed in blind people?

These connections, which are not present in normally-sighted individuals, cause an enhancement in non-visual abilities such as heightened sense of hearing, smell and touch — as well as cognitive functions such as memory and language. …

Is a blind person’s sense of hearing or smell enhanced or a blind person just doing more with the same information than a sighted person?

A new study from the University of Montreal found that blind people have no keener sense of smell than the sighted. Vision loss simply makes blind people pay more attention to how they perceive smells, the researchers said.

What are the organs that help us sense vision hearing smell and touch?

The sense organs are the body organs by which humans are able to see, smell, hear, taste, and touch or feel. The five sense organs are the eyes (for seeing), nose (for smelling), ears (for hearing), tongue (for tasting), and skin (for touching or feeling).

Do the blind hear better?

The research teams found that in the blind participants, the auditory cortex more accurately represented the frequency of each sound. “Our study shows that the brains of blind individuals are better able to represent frequencies,” Chang said.

How good is a blind person’s hearing?

How well a person can hear largely depends on how intact these hair cells are. Once lost, they don’t grow back – and this is no different for blind people. So blind people can’t physically hear better than others. Yet blind people often outperform sighted people in hearing tasks such as locating the source of sounds.

Do humans have 5 senses?

It doesn’t take much reflection to figure out that humans possess more than the five “classical” senses of sight, hearing, taste, smell, and touch. Because when you start counting sense organs, you get to six right away: the eyes, ears, nose, tongue, skin, and the vestibular system.

Do blind people have superhuman hearing?

The researchers found that blind participants showed enhanced activity in the visual region of the brain when they located sounds, indicating that they had sharpened their auditory-spatial abilities by relying on spatial hearing to navigate their environment.
