I have reported on this topic and the work of the researchers at Texas A&M Health Science Center School of Public Health previously. Here is a quick summary of their latest study, summarized by Science Daily (full citation below).
They looked at call center employees who either used a desk where they could stand while working or didn't. Not surprisingly, those who could stand up performed better. After about a month the effect kicked in, making them about 46% more productive! Earlier studies looked at cognitive function, gluteus maximus.
What is interesting in that study for us is that it apparently took a while, about a month for the subjects to become "acclimated" to the new desk structure. Their evidence for that explanation is purely speculative, however. How the "full body" process of speaking and thinking and problem solving is enhanced just by standing is a fascinating question that is not really addressed. (I work on my feet for at least an hour every morning with coffee. Not sure it is always my best stuff, but in terms of organization and clarity, it often seems so.)
We have seen something analogous in HPT. Assuming the typical pacing of a course, one 30-minute module plus about 90 minutes of homework per week, it is typically after Module 4 that it all "clicks", when generally everybody "gets it", and begins to see tangible progress. Look at the sequence:
Week 1 - Introduction to haptic learning (50% done while standing)
Week 2 - Short vowels and word stress (about 75% standing)
Week 3 - Long vowels and word stress (about 75% standing)
Week 4 - Rhythm and phrase stress (almost entirely done while standing)
Week 5 - "Aha, I get it!"
I have always assumed that it, the "Aha! I get it!" point, was primarily because of the path of the syllabus or that the patterns and techniques had become more second nature. But there may be more going on there, perhaps much more.
If you think that you got the answer . . . stand up!
