REMARKS. Sentences of twelve syllables had not been standardized previous to the Stanford revision, but Binet locates memory for ten syllables at year V, and others have followed his example. Our own data show that even 4-year-olds are usually able to repeat twelve syllables with the procedure here set forth. CHAPTER XI INSTRUCTIONS FOR YEAR V V, 1. COMPARISON OF WEIGHTS MATERIALS. It is necessary to have two weights, identical in shape, size, and appearance, weighing respectively 3 and 15 grams.[50] If manufactured weights are not at hand, it is easy to make satisfactory substitutes by taking stiff cardboard pill-boxes, about 1¼ inches in diameter, and filling them with cotton and shot to the desired weight. The shot must be embedded in the center of the cotton so as to prevent rattling. After the box has been loaded to the exact weight, the lid should be glued on firmly. If one does not have access to laboratory scales, it is always possible to secure the help of a druggist in the rather delicate task of weighing the boxes accurately. A set of pill-box weights will last through hundreds of tests, if handled carefully, but they will not stand rough usage. The manufactured blocks are more durable, and so more satisfactory in the long run. If the weights are not at hand, the alternative test may be substituted. [50] The weights required for this test, and also for IX, 2, may be purchased of C. H. Stoelting & Co., 3037 Carroll Avenue, Chicago, Illinois. PROCEDURE. Place the 3- and 15-gram weights on the table before the child some two or three inches apart. Say: "_You see these blocks. They look just alike, but one of them is heavy and one is light. Try them and tell me which one is heavier._" If the child does not respond, repeat the instructions, saying this time, "_Tell me which one is the heaviest._" (Many American children have heard only the superlative form of the adjective used in the comparison of two objects.) Sometimes the child merely points to one of the boxes or picks up one at random and hands it to the examiner, thinking he is asked to _guess_ which is heaviest. We then say: "_No, that is not the way. You must take the boxes in your hands and try them, like this_" (illustrating by lifting with one hand, first one box and then the other, a few inches from the table). Most children of 5 years are then able to make the comparison correctly. Very young subjects, however, or older ones who are retarded, sometimes adopt the rather questionable method of lifting both weights in the same hand at once. This is always an unfavorable sign, especially if one of the blocks is placed in the hand on top of the other block.
