Effortless learning of the iPA vowel "matrix" of English?

Could be, according to 2011 research by Watanabe at ATR Laboratories in Kyoto and colleagues at Boston University, as summarized by Science Daily--using fMRI technology in the form of neurofeedback tied to carefully scaffolded visual images. Mirroring what appears to go on in real time, in the experiment it was evident that " . . . pictures gradually build up inside a person's brain, appearing first as lines, edges, shapes, colors and motion in early visual areas. The brain then fills in greater detail to make a red ball appear as a red ball, for example."

This is an intriguing idea, something of a "bellwether" of things to come in the field, using fMRI-based technology joined with multiple-modality features to facilitate acquisition of components of complex behavioral patterns. The application of that approach to articulatory training alone, assembling a sound, in effect, one parameter at a time, just the way it is done by expert practitioners--should be relatively straightforward.

The EHIEP vowel matrix resembles the standard IPA matrix on the right, except that it is positioned in mirror image and includes only the vowels of English. In training learners to work within it, we do a strikingly similar build up to that identified in the study, lines < edges < shapes < motion (which is different for each vowel.) Each quadrant is then given a colour that corresponds to something of the phonaesthetic quality of the vowels positioned there. Once the "matrix" is kinaesthetically presented and practiced, it is then gradually, haptically anchored as the vowels are presented and practiced using distinct pedagogical movement patterns terminating in some form of "Guy or Girl touch" for each as the sound is articulated.

Out of the box? Not for long, my friends!

Better pronunciation? Better sleep on it!

The basic visual, pedagogical "tool" of HICP work--and the EHIEP system--is a 3 by 3 matrix enveloping the visual field in front of the learner. Vowels, stress assignment, rhythm and intonation are anchored in various ways in that conceptual space. It is, for vowels, for example, a mirror image of the standard IPA matrix. In part because learners use the "matrix" so extensively in learning and practicing target pronunciation, it is not uncommon to hear reports of them dreaming related to the experience. In a rather remarkable 2010 experiment, summarized by Science Magazine, Wamsley, Stickgold and colleagues at Harvard School of Medicine had subjects work with a maze problem--before taking a nap! Those who reported dreams related to it while asleep--performed significantly better on the problem after they woke up. Hmm . . . I have generally recommended that students do their practice in the morning before work, for any number of reasons, including just time management and having a fresher  mind and body to work with. I may reconsider, or at least begin something of an informal experiment, asking some students to practice daily after morning coffee, as usual, and the rest, just before falling asleep. Sounds promising. We'll see what happens. Until we get some "dreamy" data, however . . . better just sleep on it!
