Have you ever tried to remember a phone number just long enough to type it in? For a few seconds it sits in your head, then it slips away. A small game called Simon Says plays with that same feeling, and it can teach you something surprising about your own mind.
#What you do
The game shows you a pattern of flashing colors. You watch, then you repeat it by tapping the same order back. Easy so far. But each round adds one more flash to the end. Round one has one flash. Round two has two. Round three has three, and on it goes. Sooner or later the pattern gets longer than you can hold, and you slip. That moment is the fun part, and it is also the interesting part.
#What is really happening
When you repeat a pattern that grows by one each round, you are stretching your working memory. Think of working memory as a small mental notepad that holds only a few things at once, like a phone number before you dial it. It is not where you keep your whole life. It is the tiny scratch pad you use right now, in this second. Most people can hold about seven things on that notepad before the older ones fall off the edge. The game gently pushes you toward that edge, one flash at a time.
#Where it shows up
You use this notepad all day without noticing. You use it when someone tells you a shopping list and you try to keep it in mind to the shop. You use it when you do a sum in your head and hold the first part while you work out the second. You use it when you follow directions, left then right then left again. The game just makes the notepad easy to see, because you can watch the exact moment it fills up.
Want to feel it for yourself? play it and see how far you get.
