Test 15. Memory for designs. — Used at Devens and Dix. The designs used were chiefly 

 those of Binet and Terman. 



Section 3. — Procedure for beta trial series. 



[For the form of the blank for the beta trial series, see Part I, pp. 235 ft; for the blank of the revised beta, pp. 250 fl; and for the proceedure 

 in the revised beta, referred to below, pp. 162 fl.] 



The general directions preceding the directions for test 1 were essentially the same as those 

 for the revised beta. A rotating chart was used as an aid in demonstration. This contained a few 

 sample items for each test. The procedure followed was for the examiner to show the orderly, by 

 pantomime, what to do; then, as the subjects looked on, the orderly demonstrated the test by 

 doing all the sample items. 



Test 1. Maze. — Procedure essentially as for revised beta, except that the allotment of time 

 was 2£ minutes instead of 2. 



Test 2. Form recognition. — Turn chart to sample items and say, "PENCILS UP; LOOK." 

 Orderly watches while examiner points with pointer to standard form. Examiner shakes head 

 and says " NO " to each of the forms until he comes to the identical one, then touches the standard 

 again and says "YES," and draws an imaginary line through the identical form. Same for 

 second line of sample. Examiner then lets orderly step to the blackboard. Orderly draws line

slowly and scrutinizingly through the appropriate form in each of the four samples. When the 

 demonstration is over, the examiner holds up beta blank, points to both pages and says " ALL 

 RIGHT; PENCILS DOWN; GO AHEAD. BOTH PAGES." Orderlies see that men do not 

 stop at end of first page. At the end of H minutes say "STOP; TURN OVER THE PAGE 

 TO TEST 3." 



Test S. Number checking. — Procedure essentially as in revised beta. 



Test 4. Dot imitation,— White chart made ready. Say: "THIS IS TEST 4— THE DOTS 

 ON THE NEXT PAGE; LOOK." Orderly watches while examiner traces with pointer on the 

 chart the diagrams shown herewith, one at a time — one second per line of diagram. Most of 

 the time the pointer rests on the dots but makes sweeps relatively slowly. Orderly imitates by 

 drawing chalk lines on blackboard in appropriate places: 



After samples have been demonstrated, erase them. Then say: "LOOK, NUMBER 1; 

 PENCILS UP," and give diagram 1. Then say: "PENCILS DOWN; GO AHEAD." At end 

 of 5 seconds say: " PENCILS UP; LOOK," and give diagram 2. Repeat as before. With items 

 1 to 4 give 5 seconds for reproduction, and with items 5 to 10 give 10 seconds. After each re- 

 production, say: " PENCILS UP; LOOK." After giving each diagram, say: " GO." At end of 

 test say: "STOP; TURN OVER PAGE TO TEST 5." 



Test 5. Pictorial completion. — Essentially as for revised beta, except that the time was 5 

 minutes instead of 3.
