I've definitely read somewhere else (can't remember where) that the predictive loop is a core learning mechanism. Your brain diffs its prediction against what actually happens, and when there's a big enough difference between prediction and reality, learning occurs (ie your brain tries to change its prediction model so that it can encompass whatever it just perceived in the future).
