Spaced repetition is a technique that greatly improves your memory.
The process for spaced repetition is as follows:
- Document the things you want to remember (usually on flash cards)
- Periodically review your cards.
- Newly created cards, or cards that you’ve had trouble recalling, should be reviewed more frequently.
- As you begin to successfully remember cards, gradually reduce their review frequency.
As an example, here is how I might reinforce my memory of a Jiu-Jitsu technique using spaced repetition:
- Document the technique on a flash card.
- The next day, try to remember the technique. Walk through it in my mind. Then compare against what I wrote on the flash card.
- If I was successful in recalling the technique, try recalling it again in two days. And then four. Eventually, I’ll only be recalling techniques once a month or year.
- If I’m not able to recall a technique, start reviewing it more frequently. Once my recall improves, reduce the review frequency.
Spaced repetition can become cumbersome if you’re doing it by hand, so I recommend doing it digitally. I use an iOS app called SmartCards+ to do this on my phone.
