When I first picked up this book and began reading, echolocation really caught my attention. I was a little confused about it at first but then I read about the study done in the laboratory of Karl Dallenbach at Cornell University. Since the participants, at first, believed that it was the facial vision that was preventing them from making contact, I believed that as well. It seemed very legitimate and possible. When I read that the participants collided with the wall every time after they took off their shoes and put headphones on so they couldn't hear, I was very shocked. I can definitely understand that hearing would help a person figure out their surroundings, but I did not think it would be one of the only senses. I never realized how important sense of sound really is. I know it is necessary for survival, but reading about this study made me realize how important it is for other things as well.


  1. It is amazing how important some things that we take for granted are. I have difficulties trying to perceive what it would be like to experience the world the ways others do. I am thankful and grateful for having all of my senses. It is like the old saying, " you should not criticize someone, until you have walked a mile in their moccasins". or the man who always complained about not having any shoes, until he met a man with no feet.

  2. I feel so happy to have all of my senses. People with the obstacles they have like no sight or no hearing is a hard, but manageable disability. Definitely feel this chapter properly showed how important these senses are to us every day
