Serial Sevens

The Serial 7’s test will give the user a starting number displayed on the left. The user will then repeatedly subtract 7 from that number and enter the results on the keypad on the right of the screen. The test will always stop before negative numbers are reached. For example if the starting number is 30 you would enter 23, then 16, then 9 and finally 2. This test assesses concentration, memory and cognitive processing speed.
