Explain why there is a common misconception that people who are blind develop an "extra sense."

What will be an ideal response?


Some persons who are blind have the ability to detect physical obstructions in the environment. They often seem able to sense an object in their path. This skill has come to be known as obstacle sense. It does not mean they actually have an extra sense; rather, some people who are blind have come to be able to detect subtle changes in the pitches of high-frequency echoes as they move towards an object. This is a result of the Doppler effect that says the pitch of a sound rises as a person moves toward its source. Extraneous noise can render obstacle sense useless. People who are blind do not automatically develop better acuity in other senses, but they do make better use of sensations they obtain.
