Chapter 1 Section 2 Interesting "Facial Vision" for the Blind?
Why can blind people feel the existence of walls, can their faces really function as eyes? ? ?
People have long been amazed at the sensory ability of blind people to detect the presence of an obstacle without touching it while walking.When a blind man approaches a wall, he can stop before hitting the wall. At this time, we often hear the blind man say that he feels a wall in front of him. ?
He might also tell you that the sensation is based on a tactile sensation of some kind of vibration acting on his face. ?
For this reason, people call the blind person's sense of obstacles "face vision".The question is, do blind people really rely on their "face" to avoid obstacles? ?

For this question, Darren Bashi, a psychology researcher at Cornell University in the United States, gave an answer.In his article, he described the results of a series of experiments he and his colleagues had done on the "facial vision" of blind people. ?
The experimental process is as follows: the experimenter covers the head of the blind subject with a woolen mask and a hat, exposing the ears of the blind subject, and the blind subject who walks forward can still stop before hitting the wall.Then, the researchers removed the masks and hats of the blind people, and only wrapped the ears of the blind people with wool. Under this experimental condition, the blind people were tested one by one against the wall. ?
So the experimenters came to a conclusion that blind people's "facial vision" is wrong, they rely on hearing to perceive and avoid obstacles. ?
Mind walk?

How do we touch the world?The answer is: feeling.Usually what we refer to as sight, hearing, smell, taste, touch, etc. all belong to the category of sensation. Feeling is a wonderful thing that can neither be seen nor touched, but it is always functioning. ?
Make full use of your senses to experience this wonderful world and enrich your life. ?
