Better pronunciation? Shocking!

Always looking for new approaches to improving effectiveness of pronunciation work, especially kinaesthetic/haptic systems, like EHIEP. There are going to be some significant breakthroughs in efficiency of our work. I have looked at a number of such innovative possibilites in past posts. Here is another that could well be among those tools in the future. Based in part on the general accessibility of fMRI technology, a wide range of "electronic" interventions are in use by neurotherapists, such as this one described in a Science Daily of research by a team from NIH, Johns Hopkins and Columbia Universities. In the study subjects who got the right level of stimulation of the motor cortex (for about 20 minutes per day during a 5-day training regimen to learn a new, complex joy-stick based complex motor skill set) performed significantly better:  "tDCS (transcranial direct current stimulation) involves mild electrical stimulation applied through surface electrodes on the head, and works by modulating the excitability, or activity, of cells in the brain's outermost layers." The main effect was still strong three months later. Granted there might be some technical problems with implementing that approach right now in the classroom, but the principle, of accelerating what the researchers term "consolidation," through focused brain stimulation and biofeedback mechanisms is well established and understood. If that is not enough to get a student's motor (cortex) going, what is?

"Colorful words" about emotional interference (with pronunciation learning)

Several recent posts have alluded to the importance of cognitive-affective balance in learning and memory. In this 2011 Science Daily summary of research by Hummer, Kronenberger, Mosier, Mathews, and Wang of Indiana University, reporting the effect of playing violent video games on control of emotion, it was demonstrated (not surprisingly) that the brains of subjects at least temporarily were "reset" to have significantly lower executive function over emotional responsiveness.

Interestingly, the instrument employed, an emotional interference test, used varying intensity and hue of color on key words in the visual field related to the game structures--along with fMRI technology--to study that effect. (I have got to get ahold of the word/color set of protocols, similar to that in another related study on depression!)

Of course, we can't simply alter activity of the dorsolateral prefrontal cortex or dorsal anterior cingulate mechanically or electronically . . . (See, however, earlier posts on Neurotherapy.), but there are any number of body-based and attentional focus techniques, like the color protocols in the study, that can to some extent keep the learner more "in the game," so to speak and enhance memory and access processes. What is important is that we are beginning to "see" (through fMRI examination) how that happens in daily life and in the classroom. It is more and more potentially within our control . . .
