Imagine you’re walking down the street when your phone buzzes. “What is the capital of Maryland?” it asks you. You know the answer but you can’t quite grasp it until all of a sudden you remember: “Annapolis.” The question prompted your brain just in time.
That is the scenario envisaged by the makers of software Cerego, which launched last week, writes Hal Hodson in New Scientist:
“It uses a basic principle of cognitive science called ‘spaced repetition’ to improve learning. To remember something long term, a student must return to it several times, increasing the interval between each revision. The concept isn’t new, but Cerego aims to harness the idea to let people learn anytime, anywhere.
