Visual Memory Test

It measures short-term visual memory: how much of a pattern you can keep in mind after it disappears. It is modeled on the Visual Patterns Test, in which people see a grid with some squares filled in and then mark the filled squares on an empty grid [1].

The researchers who built that test showed that memory for a pattern seen all at once is not the same as memory for a sequence of places: some people with brain injuries did poorly on one kind of test and normally on the other [1]. The sequence memory test on this site covers the other kind.

• The squares light up together for 1.2 seconds. Then tap every square that was lit, in any order.
• Level 1 lights 3 squares, and every level adds one. The grid gets bigger as you go, so there are more places to look.
• 3 wrong taps in one round lose a life, and you have 3 lives. After a lost life you replay the same level with a new pattern.

Your level is the highest level you finished, and "squares remembered" is how many squares were lit at that level. Some patterns form an easy shape and others look random, so your level can jump between runs. This is a web game inspired by a research test, not the clinical test itself, so the scores are not comparable with clinical results.

Play in a quiet moment and on the same device each time: a bigger screen makes the grid easier to scan. Practice helps on any memory game, so the trend over several runs says more than one number.
