No.u PSYCHOLOGICAL EXAMINING IN THE UNITED STATES ARMY. 131 



Directions. — (a) Present model 1 (in each case turn the model over and call attention to the top, bottom, and sides 

 as painted or unpainted) and the nine cubes with which its counterpart may be constructed, and say, "Put these 

 blocks together as quickly as you can, so they will look just like this (point to model 1). Ready — GO! " Discontinue 

 the test if subject fails on two successive parts. 



Scoring. — With a stop-watch examiner measures in seconds the time required for the correct arranging of the cubes. 

 He also counts the number of separate moves or acts (the minimum number is 9). Every time a block is put on the 

 table or is placed in some position should be counted as a move. If subject stops work before all the cubes are in their 

 proper places, or before the time is up, he should be urged to continue; but time should be taken and errors counted 

 when subject puts lastf block in place. Each misplaced block, at the end, is counted as three moves. The presence 

 or absence of a definite plan of work is to be recorded. 



Time for work, 2 minutes. 



(5) In the same way present model 2 and the cubes necessary to construct its counterpart, saying to subject, 

 "Arrange these blocks as quickly as you can so they will look just like this (point to model 2). Ready — GO!" 



Scoring. — Same as for (a). 



Time for work, 2 minutes. 



(c) Present model 3 and the eight cubes painted on three sides and say to subject, "Now fit the blocks together 

 so they will look just like this (point to model 3). Ready — GO!" 



Scoring. — Same as for (a). 

 Time for work, 2 minutes. 



(d) Present model 4 and the cubes from which its counterpart may be constructed. The 1-inch cubes should 

 be classified according to the number of sides painted and arranged in four adjacent compartments of box (6) so that 

 subject may locate immediately any desired variety of cube. Examiner says to subject, " I want you to fit the blocks 

 together so they will look just like this (take up model 5 and turn it over). You see it is not painted anywhere. You 

 will find here (pointing to appropriate compartment of box) the unpainted block; here the ones painted on only one 

 side, and so on). Do not take out any block till you are ready to use it. Ready — GO! " 



Scoring. — Same as for (a). If subject gives up before time is called, each misplaced block is to be counted as 

 three moves. 



Time for work, 5 minutes. 



(e) Present the 27 cubes again, properly distributed in the compartments of box (6), saying, "Now, fit the blocks 

 together so that the whole of the outside (point to model 4) will be painted. P^eady — GO!" 



Scoring. — Same as for (d). 



Time for work, 5 minutes. 



iV. B. — Examiners will ordinarily find it uneconomical of time to give more than parts (a), (b), and (e). 



In scoring each part, the degree of planning should be scored: A (very good); B (fair); C (very poor). 



Test B. clock test. 



Materials. — (1) Alarm clock; (2) settings of clock.

 it?" A second trial is given with the additional setting under (a). 



Scoring. — Response, followed by a + or a — sign to indicate correctness or incorrectness. 



(6) With clock properly set and placed before subject, examiner says, "What time would it be if the two hands 

 of the clock were to trade places, so that the large hand takes the place where the small one is and the small one takes 

 the place where the large one is. " 



Scoring. — Response. Consider correct (+) if error does not exceed 3 minutes. 



Time limit, 1 minute. Record time in seconds for (c), (<£), and (c). 



(c) Same as (6), except that clock face is not visible to subject. 



(d) Same as (c). 



(e) Same as (rf).
