3. Making change. 



Ask, " If I were to buy 4 cents worth of candy and should give the storekeeper 10 cents, how much money would I get back? 

 Similarly for 15-12 cents, and 25-4 cents. Subject is not allowed coins or pencil and paper. If subject forgets problem, 

 repeat once, but not more. Spontaneous corrections allowed. 



Credit if two answers of three are correct. 



4. Four digits backwards. 



Say, "Listen carefully. I am going to read some numbers, and I want you to say them backwards. For example, if I 

 should say 5 — 1 — 4, you would say 4 — 1 — 5. Do you understand?" Then, "Ready now; listen carefully, and be sure to 

 say the numbers backwards." If subject gives digits forwards, repeat instructions. If necessary, give (6) and (c), re- 

 peating each time, "Ready now; listen carefully, and be sure to say the numbers backwards." 



Credit if one set is repeated backwards without error. 



5. Three, words in one sentence. 



Say, " You know what a sentence is, of course. A sentence is made up of some words which say something. Now, I 

 am going to give you three words, and you must make up a sentence that has all three words in it. The three words are 'boy,' 

 ' river, ' ' ball. ' Go ahead and make up a sentence that has all three words in it." Repeat instructions if necessary, but do 

 not illustrate. May say," The three words must be put u>ith some other words so that all of them together will make a sentence." 

 Give only one trial, and do not caution against making more than one sentence. Do not hurry subject, but allow only 

 one minute. Then say, "Now make a sentence that has in it the three words 'work,' 'money,' 'men.' " If necessary give 

 (e) desert, rivers, lakes, in same way. 



Credit if satisfactory sentence is given in two of three trials. (See book.) 1 



6. Finding rhymes. 



Say, " You know what a rhyme is, of course. A rhyme is a word that sounds like another word. Two words rhyme if 

 they end in the same sound. Understand? " Continue, ' ' Take the two words 'hat ' and 'cat. ' They sound alike and so they 

 make a rhyme. 'Hat,' 'cat,' 'rat,' 'bat,' all rhyme with one another. Now, I am going to give you a word and you will have 

 one minute to find as many words as you can that rhyme with it. The word is 'day. ' Name all the words you can think of 

 that rhyme with 'day.' " If subject fails, repeat explanation, and give sample rhymes for day, as say, may, pay, hay. 

 Otherwise, proceed, "Now, you have another minute to name all the words you can think of that rhyme with 'mill.' " Same, 

 if necessary, for spring. Do not repeat explanation after "mill " or "spring." 



Credit if three rhymes in one minute are given for each of two out of three words. 

 Alt. 1. Naming the months. 



Say, "Name all the months of the year." If correct, check by asking, " What month comes before April?" "Before 

 July? " " Before November? " 



Credit if months are correctly named within 15 seconds with not more than one error, and if two of three checks are 

 correct. 

 Alt. 2. Counting value of stamps. 



Say, " You know, of course, how much a stamp like this costs (pointing to a 1-cent stamp). And you know how much 

 one like this costs (pointing to a 2-cent Btamp). Now, how much money would it take to buy all of these stamps? " (showing 

 three 1-cent stamps and three 2-cent stamps). Do not tell values, where not known; if values are known but sum is 

 wrongly given, give second trial, saying, " Tell me how you got it." 



Credit if correct value is given in not over 15 seconds.

"lam going to read a sentence which has something foolish in it, some nonsense. I want you to listen carefully and tell 

 me what is foolish about it." After reading say, " What is foolish about that?" Give sentences twice if necessary, re- 

 peating exactly. If response is ambiguous, ask subject what he means.

 seconds, then I will take the card away and let you draw from memory what you have seen. Examine both drawings carefully 

 and remember that you have only ten seconds." Show card X-3 for 10 seconds, right side up. Have subject reproduce
