Drawing (and anchoring prominence) on the left side of the brain

Several earlier posts have referred to the "meaning" of the visual field, including the optimal placement of vowel schema in the visual field. Any number of visualized models of psychological and social systems have been represented on similar X~Y axes, with process being located on the X axis and positioning, on the Y axis. For example, many popular characterizations of personality preferences, management or cognitive style can be situated in that conceptual field.

In the 2007 study by Des Roches et al. (linked above; available in Abstract form only), it was discovered that when processing novelty, the right eye/left hemisphere was favoured. When the image was demonstrably negative (rather than positive) in emotional loading, there was a tendency for processing to favor the right hemisphere/left eye. The same general asymmetry appeared to be present when presented with analogous olfactory stimuli as well. (To avoid the problems of culture, individual variability and language, the research was done using 38 Arabian mares.)
          Not coincidentally, in the EHIEP framework,  anchoring of word stress, phrasal stress, discourse prominence and "front" vowels is done in the right visual field (Back vowels, however, are anchored in the left visual field, a mirror image of the typical IPA matrix display.) New information is generally anchored to the right on all protocols. Given information and emotional setting is usually established first in the left visual field.
         Most interesting--and novel study!  The research appears to provide further support for systematic exploitation of the visual field in HICP work--simply by having put the "chart" before the horse!

Thanks for linking this up to previous posts. When dealing with virtual reality is is easy to see why the CVC needs to be flipped to match neurophysiological perspectives, as uncomfortable as it is for me, having used the vowel chart to mirror the vocal tract for so long!

I also managed to access the Des Roches (2007) study through TWU library. If it helps here's the link:
