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!

(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!!!
