(1) Trust your body,
(2) Silence your mind! and
(3) Don’t be judgmental!
Actually, that is not a bad analogy for EHIEP work either. Haptic pronunciation work begins with body awareness and training. The multiple modality framework does not "silence" the mind exactly, but it certainly channels attention well. The third is the more interesting. Haptic anchoring, by its very nature, focuses on the felt sense of the target sound, not (simply, again) on incoming "sounds" through the ears. (In some exercises we ask the learner to stand up close to a mirror to get more auditory "backwash;" other times, not.) It is not uncommon for learners to be able to produce a changed vowel quality reasonably well, for example, even before they can "hear" or recognize it.
Believe it! Just try it! Trust me . . . (in reverse order, of course!)
