No.i.] PSYCHOLOGICAL EXAMINING IN THE UNITED STATES ARMY. 185 



Scoring. — No credit is to be given for time, if the blocks are not all assembled; but if they are, credit as follows: 



(a) (6) and (c) 



Seconds. Seconds. Credit. 



1-10 1-20 5 



11-25 21-30 4 



26-50 31-50 3 



51-80 51-80 2 



81-120 81-120 1 



No matter whether subject has finished or not, count each misplaced block as three additional moves and each 



unassembled block as six additional moves, and credit total moves as follows: 



(a) and (6) (c) 



Moves. Moves. Credit. 



9 8 - 5 



10-11 9-10 4 



12-15 11-15 3 



16-25 16-25 2 



26-50 26-50 1 



Note that the minimum number of moves is nine for (a) and (6), and eight for (c); that no credit is given for over 50 



moves; and that the maximum raw score is 10 points for each part, or a total of 30. 



Test 5, form board. 



Materials. — See illustration of problems, figure J, for identification of the materials. 



Directions.— Examiner places the board before subject, arranged as shown in "demonstration." E and S in this 

 figure indicate the relative positions of examiner and subject. Examiner says, " These blocks can be changed around so as 

 to make room/or this extra square, like this." Examiner proceeds to solve the problem in the minimum number of moves, 

 making sure that subject is attending. 



(a) Examiner now presents the board arranged for problem A, saying, " Without making any mare moves than you 

 have to, change these blocks around so you can find a place for the extra square (pointing to square). Don't have any blocks 

 left over. Ready — go ahead. ' ' 



(i) Examiner now presents the board arranged for problem B, saying, " I want you to change these blocks around so 

 you can find places for these two extra squares (pointing to them). Ready — go ahead." 



(c) Examiner presents the board arranged for problem C, saying, " Now I want you to change the blocks around so you 

 can find places for these four extra blocks. Ready — go ahead." 



Examiner records the time in seconds from start to finish, and counts the number of moves. A move is to be under- 

 stood as placing or trying to place a block in some position on the board. Taking a block out of position, and placing a block 

 upon the table are not counted as moves. 



Time for work on (a) and (b), two minutes each; on (c), three minutes. If (a) is not solved in the time allowed, 

 examiner demonstrates that correct solution before going on to (5). 



Scoring. — If a problem is not solved within the time limit, score that part 0; but if a correct solution has been accom- 

 plished, give credit for time and for moves as follows: 



(a) and TIME. 



(6) (c) Credit. 



0-10 0-20 5 



11-20 21-40 4 



21-40 41-70 3 



41- 70 71-110 2 



71-120 111-180 1 



MOVES, 

 (o) (A) (c) Credit. 



8 5 



9 4 



3 5 10-11 3 



4 6 12-14 2 



5-7 7-10 15-20 1 



Note that the minimum number of moves for problems (a), (b), and (e) is 3, 5, and 8, respectively, and that the 

 maximum raw scores are 8,8, and 10, or a total of 26 points. 



The examiner will find it advantageous to make a diagram of the arrangement of the blocks for each problem (as in 

 fig. J), and paste it on the screen between him and the subject. He can then copy the pattern on the board out of view 

 of the subject, and with a little practice, can do it very expeditiously — often in less than 30 seconds. 



Test 6, designs. 



Materials. — The five plates of designs on page 199. Examiner provides subject with pencil and paper. 



Directions.— The designs are given in order, (a), (b), (c), (d). Formula for (a) and (6): ''lam going to show you 

 a drawing. You will have just ten seconds to look at it; then I shall take it away and let you draw it from memory. Don't 

 begin to draw till I say 'go.' "
