no.i.] PSYCHOLOGICAL EXAMINING IN THE UNITED STATES ARMY 189 



Whether subject finishes in the time limit or not, credit is given for the degree of success he has attained as fol- 

 lows: Each maze is divided into five successive steps, which are indicated by dotted lines crossing the path of the 

 maze in the key maze, figure L. A credit of 1 point is given for each step successfully accomplished ;i. e.,for each imag- 

 inary dotted line crossed, making a total of 5 points for each maze. The openings of all blind alleys are indicated 

 by heavy black lines across the path of the maze. A penalty of 1 point is given for each imaginary heavy line crossed. 

 Thus the score equals the number of dotted lines crossed minus the number of heavy lines crossed, and maze lines crossed not 

 through carelessness (see above). Any negative score thus obtained counts as zero. (No matter how many times any 

 dotted line or heavy line is crossed, only one credit or penalty is given therefor.) 



Maximum raw score, 32 points. 



Test 9, picture arrangement. 



Materials. — Five sets of "Foxy Grandpas" pictures, one set for demonstration, and four for actual teste. 



Directions. — Examiner presents demonstrational set (x) in a row in the order 4 — 2 — 6 — 3 — 1 — 5 and says, "These 

 pictures tell a, funny story if they are placed in the right order." Examiner then proceeds to arrange the pictures 

 properly, telling the story as he does so, and calling subjects' attention to the proper sequence of the important 

 details. He next removes this set, and presents set (a), saying, "Now see how quickly you can change these pictures 

 around so as to make them tell a good story." Subject is not told if he is wrong, but examiner goes on to the next 

 set. Seta (6) to (d) are presented in the same way. The sets are shown in a row in the order 4 — 2 — 6—3 — 1 — 5 

 and 5 — 1 — 3 — 6 — 2- — 4 alternately. The time limit for each set is S minutes. 



Scoring.- — Examiner records the time and the arrangement for each set; and gives a credit of 1 point for each pair 

 of pictures in correct juxtaposition— i. e., a maximum of 5 points for accuracy for each set. When, however, the 

 error in arrangement consists only in the reversal of one, two, or three juxtaposed pairs, a penalty of 1 point is 

 given for each such reversal. Thus credit of 4 points is obtained for arrangement 1 — 2 — i — 3—5—6, which would 

 receive only 2 points credit for correctly juxtaposed pairs. 



No credit is given for time unless the arrangement is correct. Then credit as follows: 



Time. Credit. 



1-30 3 



31-60 2 



61-120 1 



121-180 



Maximum raw score, 32 points. 



Test 10, picture completion. 



Materials. — Two boards upon which are depicted successive scenes from the day's activity of a boy; and 60 small 

 blocks from which are selected the pieces to complete the pictures. 



Directions. — The boards are placed before subject, part 2 at his right. The 60 small pieces are placed above the 

 boards in the box arranged in a predetermined order 1 as indicated in the box. In this arrangement ambiguous pieces 

 are located in the same area. Examiner says, "Here is a picture — it begins here (pointing to demonstration pic- 

 ture) where the boy is getting dressed. It shows the same boy — remember, the very same boy — doing one thing after 

 another during the same day. (Examiner points along first row and then along second to indicate the sequence in 

 which the pictures come.) You see in each picture a piece is missing. Here are a lot of small pieces. They go into the 

 empty places. You are to pick out the piece that you think is needed, that is best to make the picture right. For 

 example, what is gone here?" (pointing to demonstration picture). If subject answers correctly, examiner says, 

 " That's fine. Now see if you can find the best piece for each of the other places. " If subject does not answer correctly, 

 examiner finds the piece for him, explains why it is right, and then says, "Now see, etc." as above. Examiner 

 gives no help after the first explanation, but subject is allowed to change pieces if he wishes. When subject indi- 

 cates that he has finished as well as he can, time is recorded. The time limit is 10 minutes. 



Scoring. — No credit is given for time, but the very slow are indirectly penalized by not finishing in the time limit 

 The scoring of the performance is indicated in the accompanying table. When a square is left unfilled, the score for 

 that item is 0. Negative score on the entire test counts as zero. 



Maximum raw score, 100. 



i See plate 19, opposite page 190. The pieces are numbered in order from left to right. The pieces of the top row run from 1 to 10; of th ■ 

 second row, from 11 to 21, etc. The proper numbers are stamped on the back of the pieces. Troper location for each piece in the box is indi- 

 cated by an indentical number.
