(If XVIII 2 is to be given, it should precede this test.) Provide six sheets of tissue paper, 8½ by 11 inches. Take the first sheet, and telling S. to watch what you do, fold it once, and in the middle of the folded edge cut out a small notch; then ask S. 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 S.'s inspection. Next, take another sheet, fold it once as before and say, "Now, when we folded it this way and cut 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 S. 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 S. 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; when 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 fold it once more." Avoid saying, "When we folded it once, twice, three times." After sixth response, ask, "Can you tell me a rule by which I could know 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 S. stops after one difference 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.
(a) 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?
If response is not clear, say, "Explain what you mean."
(b) 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?
