iOS Working Memory Test Support


Icon-76

The Working Memory Test app presents you with nine squares, randomly placed on the device screen, each of which contains one of the numbers from 1 to 9. Every number is used, only once.
Then you need to try to memorise the position of each number.
Tap box 1 to start. All the other squares are cleared - now try to tap the other boxes in ascending order from memory.
As each box is tapped in sequence, the number is revealed to confirm you are correct.
If you tap all nine boxes in the correct sequence, you are shown the time taken to memorise, to tap, and the total time.
If a box is tapped out of sequence, the game is lost.
The screenshots below show the game in different stages - when all the numbers are shown, the player is memorising the numbers. When some numbers are hidden, the player is entering the sequence.
Check out YouTube ("ESL Chimp's Memory") to see a chimp in Professor Tetsuo Matsuzawa's lab (at the Kyoto Primate Research Institute in Japan) memorise nine numbers in 0.65 seconds in a similar test. He does this repeatedly.
You won't beat that, but how long will you take?
Update - Version 2.0 now includes royalty-free sounds from the amazing SoundBible.com. Also changed the losing image so the user can see any numbers which may fall beneath this area.
Coded entirely in the UK using Apple’s astonishing new Swift language for simplicity and speed. Only genuine Xcode tools downloaded directly from Apple were used - along with official builds of development environments and test devices.
