Killing pronunciation 12: Memory for new pronunciation: Better heard (or felt) but not seen!

Another in our series of practices that undermine effective pronunciation instruction!
Clker.com

(Maybe) bad news from visual neuroscience: You may have to dump those IPA charts, multi-colored vowel charts, technicolor xrays of the inside of mouth, dancing avatars--and even haptic vowel clocks! Well . . . actually, it may be better to think of those visual gadgets as something you use briefly in introducing sounds, for example, but then dispose of them or conceptually background them as quickly as possible.

New study by Davis et al at University of Connecticut, Making It Harder to “See” Meaning: The More You See Something, the More Its Conceptual Representation Is Susceptible to Visual Interference, summarized by Neurosciencenews.com, suggests that visual schemas of vowel sounds, for example, could be counter productive--unless of course, you close your eyes . . . but then you can't see the chart in front of you, of course. 

Subjects were basically confronted with a task where they had to try and recall a visual image or physical sensation or sound while being presented with visual activity or images in their immediate visual field. The visual "clutter" interfered substantially with their ability to recall the other visual "object" or image, but it did not impact their recall of other sensory "image" (auditory, tactile or kinesthetic) representation, such as non-visual concepts like volume or heat, or energy, etc.

We have had blogposts in the past that looked at research where it was discovered that it is more difficult to "change the channel," such that if a student is mispronouncing a sound, many times just trying to repeat the correct sound instead, with out introducing a new sensual or movement-set to accompany the new sound is not effective. In other words, an "object" in one sensory modality is difficult to just "replace," you must work around it, in effect, attaching other sensory information to it (cf multi-modal or multi-sensory instruction.)

So, according to the research, what is the problem with a vowel chart? Basically this: the target sound may be primarily accessed through the visual image, depending on the learner's cognitive preferences. I only "know" or suspect that from years of tutoring and asking students to "talk aloud" me through their strategies for remembering pronunciation of new words. It is overwhelming by way of the orthographic representation, the "letter" itself, or its place in a vowel chart or listing of some kind. (Check that out yourself with your students.)

So . .  what's the problem? If your "trail of bread crumbs" back to a new sound in memory is through a visual image of some kind, then if you have any clutter in your visual field that is the least distracting as you try to recall the sound, you are going to be much less efficient, to put it mildly. That doesn't mean you can't teach using charts, etc., but you'd better be engaging more of the multisensory system when you do or your learners' access to those sounds may be very inefficient, at best--or downgrade their importance in your method appropriately. 

In our haptic work we have known for a decade that our learners are very susceptible to being distracted by things going on in their visual field that pull their attention away from experiencing the body movement and "vibrations" in targeted parts of their bodies. Good to see "new-ol' science" is catching up with us!

I've got a feeling Davis et al are on to something there! I've also got a feeling that there are a few of you out there who may "see" some issues here that you are going to have to respond to!!!

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

Image: Wikipedia
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!

IPA (Intra-personal physical alphabet) basics for pronunciation teaching






Had a fascinating discussion with an ESL teacher recently who maintained that knowing basic IPA for English (international phonetic alphabet) was irrelevant--for him! Asked how students are to get the pronunciation of a new word, his response was simply ("All they have to do is consult . . . ": online audio from a learner dictionary or DVD.  (For some student populations, we could probably find some common ground there!) In phonics teaching there are probably hundreds of "body alphabet" schemas and dances. (I kind of like this one!) Where he actually had it right, I think, was with use of IPA with learners--when it is not used systematically in integrated instruction. If learners cannot accurately relate the symbol to the sound, (if it is not anchored well, in EHIEP terms) it is worse than pointless--at least those sounds that are especially problematic for a learner. As noted in several earlier posts, effective use of the dictionary for anchoring pronunciation, meaning and usage is generally essential to efficient learning beyond basic functional (primarily oral) usage, which requires at least orientation to a limited set of dictionary phonetic symbols. EHIEP work begins with physically anchoring of the vowel system, first lax (what we refer to as "rough" vowels) and then tense+off glide and diphthongs (what we refer to as "dynamic" vowels), something of an "Intra-personal, physical phonetic alphabet!" The best analogy is sign language. Here is a brief Youtube clip of me doing a  the "dynamic" vowels. That is representative of the entire EHIEP system, in fact. Before long, as soon as we get the complete EHIEP haptic-videos all edited and publicly available, the training of students--and instructor--can be done in IPPPA, as well! Keep in touch.

"Matrix-style" learning with neurofeedback

Clip art: Clker
Although this 2009 study by Watanabe and Shibata of Boston University (summarized by Science Daily) relates to enhancement of only visual/perceptual learning, the potential application to the HICP visual field "Matrix," depicted at the left, analogous to the standard  IPA vowel chart, is obvious--and exciting! (The researchers do mention the possibility of extending the neurofeedback model to other modalities as well.)

Haptic engagement and anchoring of sound is not all that dissimilar, in principle, from the fMri-based neuro-therapeutic feedback being provided for subjects in the study. Quoting the summary: "At present, the decoded neurofeedback method might be used for various types of learning, including memory, motor and rehabilitation." That is good stuff. Neo and Anderton would be so proud . . .
