The numbers 1 to 20
are presented in a random order.
Your task is to click
on the numbers in the correct
order, starting with 1, as quickly as possible, but still accurately.
After that, the numbers are
rearranged automatically and
you have to click
again in the correct
order.
The numbers you have clicked on will not be marked. You won't see what you
have already clicked on.
If you make a mistake, the numbers on the screen will be
erased and you will be given an new set of numbers.
The procedure is repeated several
times and will automatically terminate
after the fifth correct
passage. At the end you
can compare
your results with a sample of
100 students.
During the exercise,
you need to be fully
focused on the task and
may not be distracted by anything.
As a start, you can try the
procedure with a simple example.
