A "reptilian brain" approach to pronunciation teaching (What Haskel says neuroscience says!)

Clker.com
Fun, superficial, slightly funky 2015 blogpost by Haskel at Neurosciencemarketing.com on marketing, appealing to the "Reptilian brain". "Appeal to neuroscience" (what was formally called "brain research") has now become one of the favorite foils of both educators and comedians. A recently discovered "bug" in the use of fMRIs may cast some additional, welcome doubt on that, in fact.  No matter what you want to "sell" . . . there seems to be some neuroscientist's often pseudo-scientific research study to back you up.

Haskel identifies 7 findings of neuroscience that suggest how to market anything (even your pronunciation teaching, I assume!) as long as you aim your pitch right at your students' "reptilian brains": pain, selfishness, contrast, tangibility, beginning and endings, visual metaphors, and "strike an emotional chord".
 
A. Pain - "All native speakers hate you because of your pronunciation or accent! Shed it!"
B. Selfishness - "Your accent is your identity, your inner Komodo. Next time somebody criticizes it, just tell them to be more multicultural and get over it!"
C. Contrast - "Have a good snake as a model: Justin Trudeau, David Cameron, Vladimir Putin or Barack Obama--take your pick."
D. Tangibility - "You do these tongue twisters long enough, they'll fix anything--including your lizard-like sun-tanned appearance."
E. Beginning and end - "Imagine your pronunciation now and how it will sound at the end of this course. Fill your mind with new sounds . . . Channel your inner cameleon (See C!)"
F. Visual metaphor - "Watch this CT-scan of me pronouncing 'th' several times tonight, especially my darting tongue." 
G. Strike an emotional chord - "All those notes in the book and in research about how hard it is to change your pronunciation are just a crock! You can do this!"

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!

"Couch potato" pronunciation learning

So what if some students, for whatever reason, cannot or decide not to participate in your choral drills or (from a haptic perspective) "move" along with the model on the video or mirror your movements as you try to correct a mispronunciation? According to Science writer, Paul, that may not be as much of a problem as you might think. Apparently, your more passive learners, "couch potatoes" are capable of getting it, too--with a few conditions attached. Research cited by Paul suggests that it is helpful if they have previously been at least exposed to the movement pattern, even better if they have actually been through it physically in some manner. In addition, if they know what to expect or know what is coming, they may pick up more as well. (In one experiment just lying still during an fMRI, so their brain activity could be monitored, as they thought about a coming test on what they were to about to watch, showed both increased activity in related motor areas and enhanced retention of movement patterns later.) But then this final challenge to the more "unmoved":

"Lastly, Grafton of UC-Santa Barbara notes that as valuable as watching others can be, multiple studies have shown that “the benefit from learning by observing is never as strong as advantages derived from physical practice.' With apologies to the couch potatoes out there, sometimes you just need to get up and dance."

Of course, the irony here is that EHIEP uses video clips (the virtual breeding ground of couch potatoes) as the basis of instruction. Turns out that, if done right, the "medium" can indeed still be experienced as the  "massage," (and not just the message) as well!
