1. repeated practice with one kind of task but learning different material each time, which facilitates the ability to learn new material.

The animals eventually became skilled at rapidly learning new discriminations, sometimes in a single trial. See learning set; transfer of training.

2. acquiring effective learning strategies such as planning; goal-setting; scheduling; using mnemonics, outlines, and flashcards; and monitoring progress.
