Using sound, the patient was able to create a crude image of basic solid shapes. This isn't sight, but this person was able to recognize the dresser in her bedroom.

Yet to lose hearing would be to sacrifice music, which is my main pursuit outside of work. Also, it would be less of a step down for me to lose sight than for many people. I was born with a deformed left eye. A strip down the middle of the retina is missing, and there's a separate, more complicated problem I've never bothered to learn about as well. I used to wear plastic-, then glass-eyes to mask it. The plastic ones were made oversized and have stretched the skin around the socket, and it became painful, but that just gave me the excuse I needed to give up wearing them altogethre. I feel proud to have a problem that isn't and not cover it up, and rarely think about it, and have friends and family completely forget about it.

    It's better to be born that way than to lose an eye for several reasons. Obviously, the pain and anguish of losing an eye. Also the need for people in that situation to redevelop their coordination. The only disadvantage is that if you don't develop parts of your sight while you are young - like me, you don't develop it at all. There will be a limit to which the brains of people given sight mid-life will be able to use them. Stereoscopic vision will be right out (even people with squints that come good can have problems with this, like my father), and they will never develop the coordination that somebody with childhood experience can.

By 1932, there was a book "Space and Sight" that concluded that "every newly sighted adult sooner or later comes to a 'motivation crisis', and that not every patient gets through it." Fortunately for this guy though, this problem seems to be more linked to people who lost their sight early, and then regained it much later, having to radically change their lives down to the tiniest mannerisms. It might have something to do with the time limitation they are putting on him, and the scientists choice of Jans, for his positive attitude.

    (* Okay, as I said what you were talking about would be of no practical use for the deaf *)

    Why not? The spectrograph allows them to "see" speach (and other sounds). Unlike sign language, the other side (speaker) does not have to learn it also.

    I am not understanding your criticism, it appears. Please try to re-word it.

    No. I am a geek. It takes years for me to get social clues.

    Anyhow, some may like it, some may not. For example, being with the family one may not have to worry about that as much.
