So, a baby beginning to walk, a guy taking guitar lessons so he play well enough to impress girls, a single mom taking real estate classes to get her real estate license and switch careers, a kid figuring out how to advance to the next level on a video game without resorting to cheat codes, a grandfather regaining lost function in a hand after a stroke, all of these reflect types of learning. These types of learning aren't all the same, don't all use the same psychological processes or require the same parts of the brain, but they're still learning according to our definition.
