no. 2] PSYCHOLOGICAL EXAMINING IN THE UNITED STATES ARMY. 371 



Test 6. Cube analysis. — Procedure essentially as for revised beta, except that the time was 4 

 minutes instead of 2$. 



Test 7. Line comparison.— "THIS IS TEST 7 ON THE OPPOSITE PAGE." Roll chart 

 into position. "PENCILS UP; LOOK." (As the verbal description of procedure is long and 

 rather pointless unless accompanied by the demonstration samples, it is not given here in detail. 

 It involves the use of covered wires of lengths corresponding to lines of samples. These covered 

 wires were laid over the lines corresponding to them, and then straightened out to show which 

 line was longest.) 



Then say: "ALL RIGHT; PENCILS DOWN; GO AHEAD." Examiner holds up the 

 booklet and points to appropriate page. 



After four minutes say: "STOP; TURN OVER THE PAGE TO TEST 8." 



Test 8. Picture sequence. — " PENCILS UP; LOOK." (Sample items are here shown similar 

 to those of the test. Examiner shows, by pointing, the correct order of pictures in these samples. 

 According to the original instructions orderly then draws arrows to show the appropriate shifts 

 to place them in correct sequence. Since this method proved difficult to score, after a few trials 

 the modification was introduced of having the orderly number the pictures to indicate sequence.) 



Examiner says: "ALL RIGHT; PENCILS DOWN; GO AHEAD. BOTH PAGES." 



After 4 minutes say: " STOP; TURN OVER THE PAGE TO TEST 9." 



Test 9. Digit-symbol. — Procedure essentially as for revised beta, except that the time was 3 

 minutes instead of 2. 



Test 10. Spot pattern. — Procedure essentially as for revised beta. 



Test 11. Pictorial analogies.— Roll blackboard to proper position. " PENCILS UP; LOOK." 

 (The verbal description of procedure will not be reproduced here. The demonstration and 

 pantomime were intended to call attention, first, to a connection or relationship between the 

 first two pictures or terms of an item, and next to a relationship between the third term and one 

 of the alternative fourth terms.) 



Examiner points to both pages and says : "ALL RIGHT; PENCILS DOWN; GO AHEAD— 

 BOTH PAGES." 



After 2i minutes say: "STOP; TURN OVER THE PAGE TO TEST 12." 



Test 12. Geometric construction. — Procedure essentially as for revised beta. 



Test 13. X-0 series (series completion). — Procedure essentially as for revised beta, except 

 that the time was 2 minutes instead of 1 minute, 45 seconds. 



Test 14- Pictorial situation. — Roll samples into position. "PENCILS UP." Pointing to 

 the empty square and to pictures to fill it. Point to first possible filler picture in first sample, 

 shake head and say "NO"; same for second and third possibilities; at fourth say "YES" and 

 nod head; point to fifth and sixth and say "NO." Motion to orderly, who then makes a cross 

 through proper filler picture. Similarly for sample 2. Orderly chooses slowly and with evident 

 effort the third and fourth samples. 



Examiner points to both pages and says: "ALL RIGHT; PENCILS DOWN; GO AHEAD— 

 BOTH PAGES." 



After 3 minutes say: "STOP; TURN OVER THE PAGE TO TEST 15." 



Test 15. Memory for designs. — " PENCILS UP; LOOK." Examiner points to sample charts 

 one at a time for 10 seconds each. Orderly watches, then reproduces. Say: "LOOK; PENCILS 

 UP." Expose first design 10 seconds, then say: "PENCILS DOWN; GO." One minute for 

 reproduction. "PENCILS UP; LOOK." Expose second design for 10 seconds. "DOWN; 

 GO AHEAD." One minute. Same for the two remaining designs. 



Designs used were those of the original Binet scale, the Terman designs from the individual 

 examinations series, and two other sample drawings of the same general type. 



Section 4. — Revision of beta trial series. 



The preliminary form of beta (15 tests) was revised in February and March, 1918, and 

 reduced to eight tests. The work was in charge of Maj. Yoakum, who was assisted by Lieuts. 

 Brigham and Otis, and Miss Cobb.
