I hate to sound overly critical of everything you say but again: there
are a few inaccuracies here. I think this is the same mistake mr. Wolf
Kirchmeir made in a point earlier.

You cannot learn reflexes. The neural loops that preform the function of
reflexes, AFAIK, have no self-modifying neural pathways.

The learning part is done by the cerebellum. It seems to be part of the
reflex because the cerebellum is (a matter of semantics, but what I'm
saying is the general idea) separate from the conscious mind. The
reflexes actually stay unmodified, but the cerebellum may learn to avoid
them from triggering and control our motor responses accordingly. The
cerebellum is good at predicting what will happen.
