You know the feeling. You stick your debit card into the ATM and then go blank when you need to punch in your PIN. Or you're standing at the checkout line, trying to recall those four digits, while the supermarket clerk and the people behind you get more agitated. (Which does nothing for your memory, by the way.)
So here's a trick to try backed by science. To memorize a list of words, draw them. To remember numbers, doodle--shade the numbers or draw things around them.
Researchers concluded both strategies much better than writing the words or numbers over and over again. Here's why: More parts of your brain (like visual memory and motor skills) are working harder when you draw than when you write things out.
So channel your inner kindergartener the next time you need to remember something important. It could be your next go-to trick.
