(Cognitive) memory hack: recall just before you forget

Filed Under did you know, regular reads, self improvement | Leave a Comment

I’m backlogged on my reading and I have just gotten around to reading this interesting (but lengthy) piece from Wired about some cool psychology hacks. I’m going to distill the key points for easier (read: less time consuming) mass consumption here. This is a very interesting memory trick. Simply put, I’m sure everyone could use a better memory.

Piotr Wozniak found a trick of how to remember stuff, and his software SuperMemo is a tool to help accomplish just that.

The problem statement and the general theory behind the solution:

SuperMemo is based on the insight that there is an ideal moment to practice what you’ve learned. Practice too soon and you waste your time. Practice too late and you’ve forgotten the material and have to relearn it. The right time to practice is just at the moment you’re about to forget. Unfortunately, this moment is different for every person and each bit of information. Imagine a pile of thousands of flash cards. Somewhere in this pile are the ones you should be practicing right now. Which are they?

The benefits:

Twenty years ago, Wozniak realized that computers could easily calculate the moment of forgetting if he could discover the right algorithm. SuperMemo is the result of his research. It predicts the future state of a person’s memory and schedules information reviews at the optimal time. The effect is striking. Users can seal huge quantities of vocabulary into their brains.
