Mostly visual perception, but we did have a chance to participate in one of the grad student's experiments. He had one of the neurological diseases/conditions, and he was using tape-delayed feedback as an analogue to the sort of signal scramble he experienced all of the time. He hoped to develop means for training those with such disabilities to be able to better cope with their distorted signal reception. I have no clue whether any of that work ever turned out, but it was an interesting idea . . .
