一個20分鐘的簡單習慣 就能讓大腦記住新資訊

西元1885年,德國心理學家赫爾曼·艾賓浩斯(Hermann Ebbinghaus),曾經做了一個與記憶力相關的實驗,而近年這個研究重新浮上水面,成為校園內幫助學生記憶課程內容的工具。

Ebbinghaus的遺忘曲線研究(The Forgetting Curve)以一小時的課堂為基礎模型,描繪我們如何保存與失去接收到的資訊。資訊的曲線最高峰(記憶最鮮明)的時候在於課程剛結束以後,而如果經過一天時間沒有再度接觸課程資料,將會失去50%-80%的記憶。

The Forgetting Curve describes how we retain or lose information that we take in, using a one-hour lecture as the basis of the model. The curve is at its highest point (the most information retained) right after the one-hour lecture. One day after the lecture, if you've done nothing with the material, you'll have lost between 50-80 percent of it from your memory.



By day seven that erodes to about 10 percent retained and by day 30, the information is virtually gone (only 2-3 percent retained). After this, without any intervention, you'll likely need to relearn the material from scratch.








Ebbinghaus' formula calls for you to spend 10 minutes reviewing the material within 24 hours of having received it (that will raise the curve back up to almost 100 percent retained again). Seven days later, spend five minutes to "reactivate" the same material and raise the curve up again. By day 30, your brain only needs two to four minutes to completely "reactivate" the same material, again raising the curve back up.




Thus, a total of 20 minutes invested in review at specific intervals and voila, a month later you have fantastic retention of that interesting seminar. After that, monthly "brush ups" of just a few minutes will help you keep the material fresh.
