Quadrupedal gait and tree climbing

Earlier today we posted on quadrupedal perspectives in locomotion. Now we find this to drive home the point.
A University of North Florida study “focused on "proprioceptively dynamic activities,” that is, ones that involved proprioception and a second factor (like locomotion or navigation) at the same time" such as climbing trees.
“All participants had their working memory tested at the start and two hours later (after climbing trees, running barefoot, and walking on a balance beam) and the researchers found that while the control groups showed no change, those who completed the proprioceptively dynamic tasks had a 50% jump in their working memory capacity.”
