The subject is shown a shape for<br />
2 seconds then a screen with<br />
variations on this shape of which<br />
two are the same. The subject<br />
must visually locate and touch<br />
the two similar shapes. When<br />
the subject touches the correct<br />
shape it changes from red to<br />
blue. If a change of colour does<br />
not occur the subject should be<br />
asked to touch with a larger<br />
surface of the fingertip. Two<br />
practice trials are given.<br />
10 trials are given. If the subject<br />
does not respond within 30<br />
seconds then this is scored a<br />
Time error and the next trial is<br />
given. If the subject touches the<br />
wrong shape then corrects the<br />
response this is scored as a<br />
Correction.<br />
