Touching tactile tactics for tapping new pronunciation?

Previous posts have alluded to the fact that students working with haptic-integrated pronunciation change often report beginning to "listen" with their bodies, as if they have recorded a word or phrase by "moving" with it or mirroring what was said. (Recent research on mirror neurons of course strongly supports that observation.) Two fascinating studies summarized by Science Daily address the underlying mechanisms which may be involved. One was conducted by researchers at Yale in which subjects were trained using a robotic device attached to their jaws to pronounce new sounds. As they did, they became substantially better at hearing them as well, noting that " . . . Learning to talk also changes the way speech sounds are heard. . . " Wow. The other, by a team at the University of British Columbia, basically "confused" subjects into thinking what they heard were aspirated consonants (when they actually heard voiced, unaspirated consonants)--by gently hitting them in the back of the neck with a small burst of air on targeted sounds. (That's right. Got to try that sometime!) The first was a bit more kinaesthetic than tactile; the second, decidedly more tactile. In both cases, the haptic or tactile "anchoring" dramatically affected perception of sounds. That is also the intent of the haptic-integrated protocols of the EHIEP system. The idea is to train learners to anchor haptically new sounds or patterns, what we call "MAMs" (more appropriate models--using movement and touch along with articulating the sound) at places in the visual field that are as "proprioceptively," visually and perceptually as distinct as possible from the learner's "inaccurate" or less appropriate current version of the sound. The summary of the latter study begins with this great line, "Humans use their whole bodies, not just their ears, to understand speech . . . " Really.

Pronunciation modelling on "cue?" You said it, MAM!

Interesting 2010 study by Luypen at the University of Pennsylvania and colleagues on the relationship between verbal cues and visual processing. They investigated the potential impact of hearing a word before it or the object it represents appears on a screen in the visual field. In effect, hearing the name first significantly enhanced subsequent visual recognition. Somewhat surprisingly, however, they also found that, " . . . A visual preview did not make the invisible target visible. Getting a good look at the object before the experiment did nothing to help participants see it flashed." What this appears to "speak to" is how to best sequence haptic feedback with pedagogical movement patterns (PMP) in instruction. For example, when a learner produces an inaccurate pronunciation of a word, the instructor, in cueing a more appropriate model (MAM), has some options:

(a) Verbally model the MAM.
(b) Do just the appropriate PMP, moving across the visual field.
(c) Verbalize the MAM while doing the PMP.
(d) Just provide the name of the PMP (in the case of vowels their numbers, such as "3y" or intonation contours, "Rise-fall" or rhythm grouping, "2-3"--indicating the number syllables appearing before after the prominent syllable).
(e) Ask the learner to do the PMP once and then try the MAM, speaking out loud.

And there are a few other possible combinations. The research seems to suggest that (d) might be the more efficient cue, first saying the name--which should evoke both the visual and haptic dimensions of the anchor before the instructor then provides feedback in the form of the PMP and MAM done simultaneously. Try it out with me in your classroom and report back either here on on the "data" blog! What's in a name? Possibly a great deal in this work.
