[The value of minus 5 is to be given to all placings where in the table below no numbers are inserted. These represent the marked absurdities.] 



VALUE OF PIECES IN PICTURES. 



(b) PROCEDURE TOR NON-ENGLISH-SPEAKING SUBJECTS. 



Examiner should take care that his directions do not appear too artificial. For this reason he should not always 

 remain absolutely silent. He should try to use whatever words are intelligible to his subject. "No," "Yes," 

 "Hurry, " etc., can be used in most cases; and even when subject does not understand, it is often better for examiner 

 to speak as well as gesture. The aim here is only to make the instructions intelligible' apart from the language used. 



Test 1 , the ship test. 



Examiner shows subject the frame with the pieces properly fitted therein. After subject looks at picture for 10 

 seconds, examiner withdraws picture, removes pieces and presents the empty frame and the pieces arranged as in 

 figure 1. Examiner points in order to subject, to the pieces, to the frame, and nods affirmatively. If subject does 

 not understand, examiner repeats. 



Test 2, manikin and feature profile. 



Examiner places pieces before subject as previously described. Then points to subject, to pieces, nods affirma- 

 tively, and sweeps hands together over pieces to indicate that they are to be assembled. This may be repeated. If 

 subject does not understand, or if pieces are not properly assembled in the time limit, examiner demonstrates part 

 (a) and goes on to (6). 



Test 3, cube imitation. 



Examiner places the cube board before subject as previously described; then taps the first imitation problem 

 slowly, puts down the tapping cube, points to subject, and nods affirmatively. If subject fails to understand, examiner 

 repeats; if he begins at the wrong end, examiner shakes head negatively, points to the first cube, and repeats the prob- 

 lem. Examiner should make sure he has subject's attention before tapping any problem.
