I am a student and I am doing a research paper for a sensation and perception psychology class and was wondering if anyone knew about a certian medical condition involving the ability of people to actually be able to 'see sound'. I saw a medical incredible show on the discovery health channel about a year ago and did not write down the name of the condition. If anyone has any information on this disorder, its name, or any possible places to look for it, I would greatly appreciate it.

Thankyou
