What is spaced repetition?
Yarno's daily quizzing is designed around a powerful learning strategy called spaced repetition.
We are better able to recall information and concepts if we learn them in multiple, spread out sessions. We can leverage this effect by using spaced repetition to learn almost anything.
Information retrieval from our brains needs to be repeated again and again, so that recall requires cognitive effort. If this effort is repeated, the neural pathways that recall a piece of information are strengthened, increasing the likelihood that you'll remember in future!
Spaced repetition is said to slow down the process of forgetting and persistence will allow us to recall with increasing accuracy over time:
Having to recall knowledge right when you’re about to forget it strengthens knowledge - even though the actual recall may feel hard at the time.
