coloured squares. A clown<br />
appears on one of the squares<br />
and then moves to another,<br />

interval between appearances.<br />
A beep signals the end of the<br />
clown’s “journey” after which<br />
the subject must repeat the<br />
journey by touching the<br />
squares on the screen. 2<br />
training sessions are given<br />
