15. DRAWING HOUSE<br />

The subject is required to copy<br />

the drawing of a house which<br />

appears on the screen. A piece of<br />

blank paper and pencil or black<br />

pen are provided by the<br />

interviewer. No practice trial is<br />

given. The interviewer indicates<br />

in the top right hand of the<br />

screen whether the test has been<br />

possible or not.<br />

A coding guide is given for the<br />

interviewer to score the test after<br />

the completion of the<br />

<strong>COGNITO</strong> battery (see section<br />

25). The interviewer clicks on<br />

each element which has been<br />

attempted in the reproduction,<br />

clicking twice if the element has<br />

been correctly executed and<br />

placed, and once if the element is<br />

present but either badly copied or<br />

misplaced.The element selected<br />

changes colour according to the<br />

number of clicks.<br />

The following appears in the<br />

Results file :<br />

- Possible or impossible to<br />

do the test for practical<br />

reasons (eg injured<br />

hand).<br />

- Refusal to perform the<br />

test<br />

- Each of the 20 elements<br />

is scored 0=absent or<br />

unrecognizable;<br />

1=present but badly<br />

done; 2=well executed<br />

and correctly placed<br />

- Perspective is indicated<br />

0=no; 1=yes<br />
