Here you can configure application settings:

A number of geometric shapes will be displayed on the screen in a short time interval.

The number of geometric shapes will vary by case.

Please look at the screen and try counting how many geometric shapes will appear on the screen.

Immediately before each task, the cross will flash several times in the center of the display.

Beware, the geometric shapes will show only once, so the same task can not be displayed again.

After the geometric shapes disappear, type the number of geometric shapes and wait for the next task.

At the end of the research, you will be informed about your results.
