@LostInParadise Unless I’m confused, you’re missing something. We’re not talking about what colors frequencies are perceived as, we’re talking about depriving the subject of an entire chunk of the frequency spectrum. Do you really think that it’s impossible for there to be an intuitive awareness (conscious or not) that there is something missing? Even if the missing chunk is on the end of the perceivable spectrum and the subject doesn’t have the benefit of having the beginning and the end of the pattern, you don’t think that there can be an instinctive expectation to see the full spectrum that might trigger the intuition?
by the way, if I have a point, shame on you for being all like “this is my final comment” :P
edit: I’ve read up on colorblindness, and I see your point more clearly. But, I still suspect that it is possible for an unconscious awareness of the spectrum of light humans see in might reveal itself in someone who is deprived of a length of that spectrum. I think people just adapt so quickly to whatever senses they have, there isn’t much sensitivity to it. But, if an experiment like this were done and the subject was exposed to even scaling in light frequency, but for one missing unit, I think it might cause an awareness.
