If you look at the first 3 boxes, and if you care to google for more follow up on those terms, go for it.

If you think I'm wrong, that's fine too. I can't devote any more time to this right now.
Biological systems are plastic, but they have inherent limits. I personally believe phoneme categorical perception of previously unheard phonemes in adults to be one of those limits.
