What do you expect? (A "Tsough" question for pronunciation teaching!)

Intriguing title of  recent piece/summary on ScienceDaily.com: "Flaw in Rubber Hand Illusion raise tsough questions for psychology" (a real double threat: not only a spelling miscue, but a grammar issue as well.)  Do those two little "glitches" affect your expectations as to what is in the article? Unavoidably, eh . . . and that is too bad. The research by Lush of University of Sussex being summarized is potentially paradigm shaking (original title): Demand Characteristics Confound the Rubber Hand Illusion.

From the summary: 

Clker.com

"The Rubber Hand Illusion, where synchronous brush strokes on a participant's concealed hand and a visible fake hand can give the impression of illusory sensations of touch and of ownership of the fake hand, has been cited in more than 5,000 articles since it was first documented more than 20 years ago."

What that appeared to establish early on is that the brain was in some sense "hard wired" to tranfer sensation throughout the body, as a function of consciousness. The problem, according to Lush, and demonstrated in the study, is that the results from experiments exploring that effect, may be hopeless biased by what are termed "demand characteristics," of the study, in effect (hypnotic-like) suggestion as to what the researcher expects to find and the subjects experience. 

In other words, subjects will do their best to exhibit the effect being elicited. In Lush's study, subjects' expectations for how they would respond to the "rubber hand", having read the original introductory protocols, were striking to the extent that they were biased in favor of experiencing the "ghost sensations" in the rubber hand. 

Since in haptic pronunciation teaching the hands play a central role in linking sound, gesture and concepts, we clearly have a "pony in this race" as well.

A couple of decades ago, in a piece on the role of suggestion in language teaching in the JALT Language Teacher, I cited a paragraph from a (then) popular student pronunciation book (bold-face, mine):

"Acquiring good pronunciation is the most difficult part of learning a new language. As you improve your articulation you have to learn to listen and imitate all over again. As with any activity you wish to do well, you have to practice, practice, practice, and then practice some more . Remember that you cannot accomplish good pronunciation overnight; improvement takes time. Some students may find it more difficult than others and will need more time than others to improve" (Orion, 1989, pp. xxiii-iv).

I went on to note: "In those . . . words and phrases . . . can you not hear echoes of that famous line above the door in Dante's Inferno, "Abandon hope, all ye who enter here?"

This relates back to two blog posts ago on "pronunciation preambles," that is the way instructors set up work in pronunciation. Human beings, at least most of them, are highly suggestable. They have to be to be capable of picking up subtle cues in their environment quickly and efficiently. Pronunciation teaching, and pronunciation, in general, has gotten a bad rap, some of it deservedly so, of course, but how it is presented to learners, consciously and subconsciously, makes an enormous difference in outcome.

A "slight of hand" in the truest sense. What are you suggesting?
