Learning runs through acquiring, retaining and retrieving, and each stage fails on its own

Learning, understood as a relatively permanent change that comes from experience, runs through three stages: acquiring, retaining and retrieving. Each one can fail on its own, and that is why each one asks for something different. Acquisition is the first contact: you take in the new information, encode it and start practising the basics.
