It might make a lot of sense actually. It could serve to speed up instinctive responses to stimuli which have been encountered before, i.e. whipping your finger away from a hot surface.

I think I understand what you're getting at, but the example you gave is not a learned act, it's a reflex action. It bypasses your brain entirely, you generally recognize the pain after you reflexively withdraw your hand.

Reflexes can be, and are frequently, modulated by parts of the nervous system more inclined to learning.
