We do not believe, however, that this fault is serious enough to warrant the elimination of the test. The fact is that in a large majority of cases the score which it yields agrees fairly closely with the result of the scale as a whole. Subjects more than a year or two below the mental age of 10 years seldom succeed. Those more than a year or two above the 10-year level seldom fail. There is another reason why the test should be retained, it often has significance beyond that which appears in the mere number of words given. The naming of unusual and abstract words is an instance of this. An unusually large number of repetitions has symptomatic significance in the other direction. It indicates a tendency to mental stereotypy, so frequently encountered in testing the feeble-minded. The proportion of repetitions made by normal children of the 10- or 11-year intelligence level rarely exceeds 2 or 3 per cent of the total number of words named; those of older retarded children of the same level occasionally reach 6 or 8 per cent. It is conceivable, of course, that a more satisfactory test of this general nature could be devised; such, for example, as having the subject name all the words he can of a given class (four-footed animals, things to eat, articles of household furniture, trees, birds, etc.). The main objection to this form of the test is that the performance would in all probability be more influenced by environment and formal instruction than is the case with the test of naming sixty words. One other matter remains to be mentioned; namely, the relative number of words named in the half-minute periods. As would be expected, the rate of naming words decreases as the test proceeds. In the case of the 10-year-olds, we find the average number of words for the six successive half-minutes to be as follows:-- 18, 12½, 10½, 9, 8½, 7. Some subjects maintain an almost constant rate throughout the test, others rapidly exhaust themselves, while a very few make a bad beginning and improve as they go. As a rule it is only the very intelligent who improve after the first half-minute. On the other hand, mentally retarded subjects and very young normals exhaust themselves so quickly that only a few words are named in the last minute. Binet first located this test in year XI, but shifted it to year XII in 1911. Goddard and Kuhlmann retain it in year XI, though Goddard's statistics suggest year X as the proper location, and Kuhlmann's even suggest year IX. Kuhlmann, however, accepts fifty words as satisfactory in case the response contains a considerable proportion of abstract or unusual words. All the American statistics except Rowe's agree in showing that the test is easy enough for year X. X, ALTERNATIVE TEST 1: REPEATING SIX DIGITS The digit series used are 3-7-4-8-5-9; and 5-2-1-7-4-6.
