That's really interesting. You mean other than martial arts? How is this done?
Adding to the other posts, children learn pretty much everything in a formal setting by Kata. When I was teaching English, a lot of kids would mimic not just my pronunciation, but also my gestures and body language in order to get it. Also, when my daughter was in kindergarten in Japan, the teachers there would teach the kids basic skills, like doing up shirt buttons and folding clothes by showing them in a step by step manner the "set" way to do it. The kids would then repeat the "set" way until they could do it "properly" (i.e. the "set way). When I was training with adults and kids in budo, everyone would constantly (some would say obsessively) mimic the instructor, even while the instructor was verbally explaining something. Basically, they watch, copy and learn, and in general, can pick up a lot of detail. It's a great skill to have, and I suppose most aikido and budo practicioners do this to some extent, but the level generally done in Japan is quite hard to recreate in "the West" We just have a different approach to learning. BTW, this has positives and negatives, but it is definitely a Japanese cultural hallmark.
