Beginner's Guide to Memory

Key takeaways

• Memory works in three stages, getting information in, keeping it and getting it back out, and most everyday forgetting happens at the first stage.
• Working memory holds only a handful of items for a few seconds, so repeat or write down anything important before your attention moves on.
• Pay attention on purpose: say it aloud, link it to something you already know, and do one thing at a time.
• Test yourself instead of rereading, because the effort of pulling an answer out of memory is what makes it last.
• Revisit new material after a day, a few days and a week, because spaced reviews outlast one long cramming session.

Inside this bit

1. What memory really is

   Memory is the ability to take in information, keep it and bring it back when you need it. Those three stages have names you will meet throughout this book: encoding is getting information in, storage is keeping it over time, and retrieval is getting it back out.

2. The words that explain your memory

   A few terms make everything else easier. Working memory is the small mental notepad you use right now, to hold a price while you compare it or a number while you dial it.

3. Why we forget, and why that is normal

   Forgetting has four common causes, and each has a different fix. Sometimes the information was never encoded, because your attention was elsewhere when it arrived.

4. First move: pay attention on purpose

   Because so much forgetting starts at encoding, the first move is to notice when something needs remembering and give it full attention for a few seconds. Three small actions make that attention count.

5. Second and third moves: test, then space

   Once something is in, the best way to make it stay is to pull it back out. This is called retrieval practice, and it simply means testing yourself: close the book, cover the answer, and try to produce it from memory before checking.

6. Classic beginner mistakes and a steady start

   Beginners tend to make the same few mistakes. They reread and highlight, which builds familiarity that feels like knowing.
