Fixing your eyes on better pronunciation--or before it!

Early on in the development of haptic pronunciation teaching, we began by borrowing a number of techniques from Observed Experiential Integration therapy, developed by Rick Bradshaw and colleagues about 20 years ago. OEI has proved to be particularly effective in the treatment of PTSD.  In OEI one of the basic techniques is the use of eye tracking, that is therapists carefully control the eye movements of patients, in some cases stopping at places in the visual field to "massage" points through various loops and depth of field tracking.

We discovered that attempting to control students' eye movement, having them follow with their eyes the track of the gestures across the visual field being used to anchor sounds during pronunciation work, that although memory for sounds seemed better, the holding of attention for such extended lengths of time could be really counterproductive. In some cases, students even became slightly dizzy or disoriented after only a few minutes. (And, in retrospect, we were WAY out of our league . . . )

Consequently, attention shifted to visual focus on only the terminal point in the gestural movement where the stressed syllable of the word or phrase was located, where the hands touched. We have been using that protocol for about a decade.

Now comes a fascinating study by Badde et al., "Oculomotor freezing reflects tactile temporal expectation and aids tactile perception" summarized by ScienceDaily.com, that helps refine our understanding of the relationship between eye movement and touch in focusing attention. In essence, what the research demonstrated was that by stopping or holding eye movement just prior to a when subject was to touch a targeted object, the intensity of the tactile sensation was significantly enhanced. Or, the converse: random eye movement prior to touch tended to diffuse or undermine the impact of touch. That helps explain something . . .

The rationale for haptic pronunciation teaching is, essentially, that the strategic use of touch both successfully manages gesture and focuses much more effectively the placement of stressed syllables in words accompanying the gesture in gesture synchronized speech. In almost all cases, the eyes focus in on the hand about to be touched--just prior to what we term the: TAG (touch-activated ganglia) where touch literally "brings together" or assembles the sound, body movement, vocal resonance and iwth graphic visual schema and meaning of the word or phoneme, itself.

In other words, the momentary freezing of eye movement an instant before the touch event should greatly intensify the resulting impact and later recall produced by the pedagogical strategy. We knew it worked, just didn't really understand why. Now we do.

Put your current pronunciation system on hold for bit . . . and get (at least a bit) haptic!
