This test is a lot harder than it looks! VSTM measures your visual memory. You’ll see four colored boxes flash quickly on the screen. After a short delay, you’ll be shown a new colored box and have to decide if it matches one of the four that you saw before. Press the MATCH key if it does, NO MATCH if it doesn’t.
Your visual memory is one of the most important pieces of your cognitive health, since so much of the information we receive in our culture comes in visual form. E-mails, books, signs, the web, and television are all densely visual media. In a fast-paced world, organizing and recalling visual information is a large part of cognition.
