Many in the field "look down on" using gesture and body movement extensively in pronunciation teaching; some of it is deserved, of course. But a new study adds an interesting new twist: upper torso "nodding" (at least in English), often observable when a native speaker is speaking rhythmically or stressing words in speech. (Note: This is a bit of stretch--literally, of the neck--but hang with me. My "discovery" of the upper torso nod early on was simply a game changer.)
In a study by Fumiaki Sato of Toyohashi Institute of Technology and colleagues (Summarized by Neurosciencenews.com) titled, Backward and forward neck tilt affects perceptual bias when interpreting ambiguous figures, subjects were shown three-dimensional cubes in their visual field where they had to either look up to focus on it, or look down to identify which of two or three others they were looking at. Basically, when nodding their head down slightly they were able to identify the cube more quickly than if they were looking up at it. (Moving to the left or right did not evoke an analogous difference in perception.) Fascinating study . . . The researchers' discussion focuses on the role of that postural adjustment in affecting perception, without speculating further as to the implications of that finding. Allow me!
In 1987, on my way to a convention, I observed two strikingly different upper torso nods associated with the words, Coconut Cheeseburger. (For the full story, see the blog post on it from 2015.) One person, trying to explain why his friend had mistakenly received a 'coconut cheeseburger,' was claiming that what had been said was "coconut cheeseburger," used one torso nod, culminating on 'cheese.' The other person, argued that what she had actually said was, "Coke and a cheeseburger," using two torso nods, one on 'coke' and one on 'cheeseburger." You see the problem. Said with one torso nod--given that there was a sandwich of that description at time in the Florida Keys--the misunderstanding is . . .well . . understandable.
In haptic pronunciation teaching--and perhaps all teaching in some sense in English, that basic pendulum-like motion of the body rhythm in speaking is fundamental, reflecting the muscles of the upper and lower chest, and diaphragm, coming together to expel air up and out through the vocal cords. At the "bottom" of each nod is where there should be, according to the research, at least some greater clarity and focus. If you "think" about, that downward motion of upper torso can have meaning in interpersonal communication from several perspectives.
Some it, of course, is just visual marking of stress assignment, similar to the "baton" gesture. It can also, however, signify other concepts externally, such resignation or confidence or, depending on the speed of the gesture, varying degrees of engagement or energy involved. Regular, uncluttered rhythmic torso nods can imply semantic coherence in the speaker, that what is being said is thoroughly integrated at that point in time. Any highly accomplished public speaker generally has near total control and expressive use of upper torso "nodding" as well.
In haptic work, almost every one of the three dozen or so designed gestures may be accompanied by an upper torso nod, depending on whether the stretch of speech is being articulated in "pieces" for some pedagogical purpose or fluently, approaching natural speech. In effect, the torso, not the head and arms is where the "action" is. How's yours?
See what I mean? If not, set up a video camera off to your left or right as you teach. Note when your speech is generally synced with your upper torso nods, and when it is not. If it is, well . . . take a bow! Then join us at www.actonhaptic.com!
