Balance between cultures: equilibrium training

Way back in January, I posted ‘Equilibrium, modularity, and training the brain-body.‘ At the American Anthropology Association annual meeting, I presented my current version of this research, significantly updating it with ethnographic material from Brazil, a comparative discussion of different techniques for training balance, and a series of graphics that I hope help to make my points. The title of that paper was ‘Balancing Between Cultures: A Comparative Neuroanthropology of Equilibrium in Sports and Dance.’

I’ve decided to post a version of this paper here, with the caveat that it’s still a work-in-progress. I’d be delighted to read any feedback people are willing to offer.

As a cultural anthropologist interested in the effects of physical training and perceptual learning, I see ‘neuroanthropology’ as a continuation of the cognitive anthropology advocated by Claudia Strauss and Naomi Quinn (1997).

The new label, however, reflects engagement with a new generation of brain research, what Andy Clark (1997) refers to as ‘third wave’ cognitive science, or work on embodied cognition.1 Much of the ‘third wave’ does not focus strictly on what we normally refer to as ‘cognition,’ that is, consciousness, memory, or symbolic reasoning. Rather embodied cognition often highlights other brain activities, such as motor, perceptual and regulatory functions, and the influence of embodiment on thought itself; this is the reason I’m thrilled to have endocrinologist Robert Sapolsky as part of this panel, as his work is part of the expanded engagement of neuroanthropology with organic embodiment.2.

My own entry into neuroanthropology results from three influences: a phenomenological interest in cultural variation in human perception, anthropological study of embodiment, and apprenticeship-based ethnographic methods. This method posed an odd question during my field research on the Afro-Brazilian martial art and dance, capoeira. Simply put, as a devoted apprentice-observer, I failed to maintain hermeneutical agnosticism and started to ask, ‘Is what my teachers and peers report — and I too seem to be experiencing — plausible?’

Fall prevention in older people — Stephen Lord at HCSNet

Daniel isn’t the only guy at Neuroanthropology who gets to go to good conferences; last week, while in the throes of a cold brought on by fieldwork with the 15-and-under Sydney city select rugby team, I got to go to the HCSNet Workshop on Speech, Perception and Action held at Western Sydney University.

HCSNet is funded by the Australian Research Council to promote research on human communication. I only got to go to the second day of the two-day conference (because I was cooking meals for 20 hungry rugby hopefuls the first day), but I saw a number of great presentations, including talks by Catherine Best, MARCS Auditory Laboratories, UWS, Beatriz Calvo-Merino, University College London, and Stephen Lord, Prince of Wales Medical Research Institute. I’ll blog soon on Dr. Calvo-Merino, one of the high points of the day, but today I want to make some notes on Prof. Lord’s fascinating research and talk.

Prof. Lord heads the Falls and Balance Research Group. Visit the group’s website for publications and some great information about risk factors for falling. At the conference, Lord discussed the group’s extensive applied research examining different factors that contribute to older people falling and experimental interventions to decrease the contribution of any single factor. The project has created a screening procedure for use by general practitioners to evaluate an older person’s likelihood of falling.

As regular readers know, I’m particularly interested in the way humans maintain equilibrium (see earlier posts, Kids falling down and Equilibrium, modularity, and training the brain-body, and Daniel’s post of some great parkour video, Free Running and Extreme Balance). In the longer of these posts (Equilbrium, modularity…), I specifically discussed how the ‘sense of balance’ is actually a much more complex synthesis of multiple sensory inputs, both exteroception (perception of the world) and interoception (perception of the self).
