XIV. 



1. Vocabulary. See pages 181-182. 



2. Induction test. 



(If XVIII-2 is to be given, it should precede this test.) Provide six sheets of tissue paper, 8J by 11 inches. Take 

 the first sheet, and telling subject to watch what you do, fold it once, and in the middle of the folded edge cut out a small 

 notch; then ask subject to tell you how many holes there will be in the paper when it is unfolded. Whatever the answer, 

 unfold the paper and hold it up broadside for subject's inspection. Next, take another sheet, fold it once as before and 

 say, ' ' Now, when we folded it this way and tore out a piece, you remember it made one hole in the paper. This time we will 

 give the paper another fold and see how many holes we shall have." Then proceed to fold the paper again, this time in the 

 other direction, cut out a piece from the folded side, and ask how many holes there will be when the paper is unfolded. 

 Then unfold the paper, hold it up before subject so as to let him see the result. Whatever the answer, proceed with 

 the third sheet. Fold it once and say, " When we folded it this way there was one hole." Fold it again and say, "And 

 when we folded it this way there were two holes." Fold the paper a third time and say, "Now, I am folding it again. How 

 many holes will it have this time when I unfold it?" Again unfold paper while subject looks on. Continue in the same 

 manner with sheets, four, five, and six, adding one fold each time. In folding each sheet recapitulate results, saying 

 (with the sixth, for example) : " When we folded it this way there was one hole; when we folded it again there were two; u<hen 

 we folded it again there were four; when we folded it again there were eight; when we folded it again there were sixteen; now 

 tell me how many holes there will be if we foldit once more." Avoid saying, "When we folded itonce, twice, three times." 

 After sixth response, ask, "Can you tell me a rule by which Icouldhnow each time how many holes there are going to be?" 



Credit if answer to sixth question is correct, and governing rule is correctly stated. 



3. President and king. 



Say, " There are three main differences between a president and a king; what are they?" If subject stops after one dif- 

 ference is given, urge him on, if possible, until three are given. 

 Credit if two of the three correct answers are given. 



4. Problem questions. 



Say, "Listen, and see if you can understand what I read." Then read the problem slowly and with expression. If 

 necessary, re-read problem. 



(o) A man who was walking in the woods near a city stopped suddenly very much frightened, and then ran to the nearest 

 policeman, saying, that he had just seen hanging from the limb of a tree a a what? 



(6) My neighbor has been having queer visitors. First, a doctor came to his house, then a lawyer, then a minister (preacher 

 or priest). What do you think happened there? 



(c) An Indian who had come to town for the first time in his life saw a white man riding along the street. As the white 

 man rode by, the Indian said: ' ' The white man is lazy; he walks sitting down.' ' What was the white man riding on that caused 

 the Indian to say, "He walks sitting down"? 



Credit if two of the three problems are satisfactorily answered. 



5. Arithmetical reasoning. 



Give subject card XIV-5, exposing problems one at a time. Have subject read each problem aloud and, with the 

 printed problem still before him, find the answer without the use of pencil or paper. In the case of illiterates, examiner 

 reads each problem for subject two or three times. 



Credit if two of the three problems are correctly solved, within one minute each. 



6. Reversing hands of clock. 



Say, "Suppose it is six-twenty-two o'clock, that is, twenty-two minutes after six; can you see in your mind ivhere the large 

 hand would be, and where the small hand would be?" "Now, suppose the two hands of the clock were to trade places, so that 

 the large hand takes the place were the small hand was, and the small hand takes the place where the large hand was, v;hat time 

 would it then be?" Repeat the test with the hands at 8.08 (8 minutes after 8), and again with the hands at 2.46 (14 

 minutes before 3). 



Credit if two of the three problems are solved with reasonable accuracy. (See book).
