Welcome to the cognitive function test

This test consists of four parts.

Please do not worry if you find the later tests difficult. They are designed so that nobody is able to finish all of them.

Please take time to read the instructions carefully before starting any part of the test.

Please do not be tempted to skip the examples.

Where the tests are timed, the timer will start when you press the 'START TEST' button so you will need to be ready.

The 'NEXT' and 'START TEST' buttons will always be in the lower right hand quarter of the screen.
