Drawing on the concept of the "body alphabet", creating stylized body movement that iconically represented letters and sounds, we developed the haptic pronunciation teaching system, beginning in about 1985. New gestures were created that visually and somatically represented in tangible and recognizable ways, sounds, graphemes and a range of phonological processes, such as vowels, phrasing of syllables and intonation patterning. Those routines were intentionally designed to not carry common problematic social meanings, such as waving goodbye or signalling some degree of pleasure or displeasure.
Just read a remarkable piece of neuroscience research that seems to get at some of the critical, underlying mechanisms involved: Relating visual production and recognition of objects in human visual cortex, by Fan, et al. (2019).
Quoting the summary from Science Daily:
"As the participants drew each object multiple times, (line drawings of pieces of furniture) the activity patterns in (visual) occipital cortex remained unchanged, but the connection between occipital cortex and parietal cortex, an area involved in motor planning, grew more distinct. This suggests that drawing practice enhances how the brain shares information about an object between different regions over time. . .This means people recruit the same neural representation of an object whether they are drawing it or seeing it."
Especially for the more kinaesthetic among us, sketching, allowing the pen or brush, or the body itself a more prominent role in supporting memory can be wonderfully enabling and effective. One has to wonder, however, what we are doing to our collective memories and coming generations as we "hand off" more and more of our primary encoding and recalling to our essentially visual-auditory smartphone interfaces. Research on that question and the general interconnectivity between areas of the brain is extensive and growing rapidly.
The implications of that observation and many like it recently are paradigm changing. Much of what we have come to understand as relatively isolated sections and functions of the brain, and by extension our behavior, are really anything but. The bad news and the good news:
In effect, everything we experience at any given moment can contribute substantially to what is later remembered and recalled. We, as educators or influencers, are accountable for much more, but, on the other hand, we now have license to do more as well.
v5.0 of the haptic system is about to launch. It does more . . .
