The ab6ve has to exceptions. ln the sub-test No. 1, put the tuo pieces side by side. ln sub-test s put the pieces in two piles. ln one pile, put pieces 1 to 6, and in the second by its side, pieces 7 to 12. Pieces 1 7 will thus appear before the subject on top side by side to give him the initial correct start.

The time limit is 2 minutes each for sub-tests to 3 and 3 minutes each for sub-tests Nos. 4 and 5. Record both.the time taken by the subject and failure or success.
(4) watch the subiect while he is drawing. lf he repeats a line or lifts his pencil, remind him of the conditions. Ask him to commence after proper thought. lf he makes a drawing wrong, cross lt out and ask him to start a fresh. Encourage him'to try as many times as he likes within the time lirnit before you record a failure in a particular pattern. o
The solutions are given at the back of the cards. Try out the patterns yourself first. You will be able to see the device. Solutions other than those given are also possible and should be familiar to you.
