In "The Sight of Touch" 24-year-old Michelle Geronimo was blindfolded and studied Braille for five days so scientists could see whether this radical change in incoming information would promote particular adaptations in her brain. Recently, we asked her some questions about her 100 hours without sight.

Why did you volunteer for this study?

The study gave me the chance to experience what it is like to function in a world without sight. I entered the study to gain a better understanding of the challenges blind individuals face and a better appreciation for my vision. I decided to volunteer without much hesitation at all. What other time would I have an opportunity like this, to be totally blindfolded for a week and in a safe, controlled environment?

I also wanted the opportunity to receive Braille and cane instruction. I have always been fascinated by Braille- a whole other method of communication- so I jumped at the chance to take one-on-one lessons. I was also interested in the cane instruction and other techniques for getting around.

Although I was very glad to receive the $1,170 stipend, I honestly would have volunteered for the study without one. The overall experience and resulting reflections have been compelling enough to make me refer all of my friends to participate as well.

Describe your first day.

I checked in Sunday night, which was a good idea, because then I knew what the room looked like. I was then blindfolded Monday morning. Things were a little hectic because Scientific American Frontiers was there to film with Alan Alda. It was kind of exciting. We'd be sitting there blindfolded together, then learning caning together, and then learning from the Braille instructor. It's kind of a different experience saying, "Yeah I was blindfolded in a study" and, "Oh yeah, I was blind folded with Alan Alda, to boot!".

Once I was back in my room alone, the radio and noises from the hallway seemed magnified. They kind of spooked me that first day. I think being blindfolded and in a strange environment for a week made me feel more vulnerable. I didn't want the radio up very loud at all, because I couldn't hear if someone was walking in the door. I wouldn't be able to distinguish other sounds that were happening around me. I don't know if my hearing was more heightened or if I was just more aware because that's all I had.
