What does a born blind person see?
A person who is born blind has dreams but doesn’t see images. Dreams could include sounds, tactile information, odors, flavors, and feelings. On the other hand, if a person has sight and then loses it, dreams may include images. People who have impaired vision (legally blind) do see in their dreams.
Can people born blind visualize things?
Yes, blind people do indeed dream in visual images. For people who were born with eyesight and then later went blind, it is not surprising that they experience visual sensations while dreaming. Therefore, people who are blind since birth still technically have the ability to experience visual sensations in the brain.
How do born blind people see the world?
Blind people perceive the world by using other senses, and even master the technique of echolocation for sight. A 20/200 vision means we would need to stand 20 feet away from an object to see it as clearly as a person with 20/20 vision could see it from 200 feet.
Will blind see dreams?
People who were born blind have no understanding of how to see in their waking lives, so they can’t see in their dreams. But most blind people lose their sight later in life and can dream visually. Danish research in 2014 found that as time passes, a blind person is less likely to dream in pictures.
How do blind people learn about color?
Color is a surface property of an object, but there’s no way for me to tell a blind person what that sensory experience is, because it’s a purely visual experience. So the way they learn about red is the way you and I learn about quarks, or about concepts like justice or virtue — through a verbal description or use in verbal contexts.”
How do blind people build Pictures?
Gabias, like many blind people, builds pictures using his sense of touch, and by listening to the echoes of clicks of his tongue and taps of his cane as these sounds bounce off objects in his surroundings, a technique called echolocation. “There’s plenty of imagery that goes on all the time in blind people,” he told Life’s Little Mysteries.
Do congenitally blind people see red?
“We found that, in the congenitally blind, the neural responses for red were in the same areas as the neural responses for justice,” he said.
Can blind people understand quarks?
With no way to directly experience what something like quarks actually are, Caramazza said, people lean heavily on language to understand or describe them — using words like “strange” and “charm” to describe quarks’ “flavors.” And the same, he said, is true for blind people seeking to understand color.
