The learning you do while your attention is divided might stick with you in the short-ish term but not in the long term.
Norman Doidge writes in his book The Brain that Changes Itself about Merzenich and Jenkins‘ research on monkeys’ learning. They found that automatic learning did result in some remapping of neuropathways, but the remapping didn’t last long unless the monkey paid close attention during (more…)
