A screen is presented with 9
coloured squares. A clown
appears on one of the squares
and then moves to another,
remaining on each for one
second, with a one second
interval between appearances.
A beep signals the end of the
clown’s “journey” after which
the subject must repeat the
journey by touching the
squares on the screen. 2
training sessions are given
with 2 and then 3 squares. The
subject is given 8 trials of
increasing length from 2 to 9
squares.
The following appears in the
Results file :
- Correct or incorrect

- The sequence in
which the squares are
touched (each square
has a number for this
purpose)
