SUMMARY OF CHANGES A comparison of the above list with either the Binet 1908 or 1911 series will reveal es On the whole, it differs somewhat more from the Binet 1911 scale than froroup in the 1911 scale, 2 are eliminated and 29 are relocated Of these, 25 are moved doard and 4 upward The shi+fts are as follows:--

Down 1 year, 18 Down 2 years, 4 Down 3 years, 2 Down 6 years, 1 Up 1 year, 3 Up 2 years, 1

Of the adult group in Binet's 1911 series 1 is eliminated, 2 are moved up to ”superior adult,” and 1 is ly, of Binet's entire 54 tests, we have eli only 19 in the positions assigned theits, resisting suggestion, and ”reversed triangle”

The revision is really est, since reat many tests in order to ned the have been worked over anduniformity This phase of the revision is perhaps more important than the mere relocation of tests Also, the addition of nues of the scale affects very considerably the es above the level of 10 or 11 years

EFFECTS OF THE REVISION ON THE MENTAL AGES SECURED The most ies secured in the lower ranges of the scale, and to raise considerably the es above 10 or 11 years This difference also obtains, though to a somewhat smaller extent, between the Stanford revision and those of Goddard and Kuhl by the Stanford revision between 12 and 14 years, and ere therefore somewhat above the level of feeble-mindedness as that term is usually defined, 50 per cent tested below 12 years by the Goddard revision That the dull and border-line adults are so uished from the feeble-minded by the Stanford revision than by other Binet series is due as roups as to the relocation of existing tests

On the other hand, the Stanford revision causes young subjects to test lower than any other version of the Binet scale At 5 or 6 years the e from 6 to 10 months lower than other revisions yield

The above differences are nificant than would at first appear

An error of 10 e of a 5-year-old is as serious as an error of 20the error in terence quotient makes it e of a 5-year-old ence quotient A scale which tests this ence quotient of 75 (which ordinarily ence) to test at 90, or only slightly below norreat ease of the original Binet scale at the lower end, and its too great difficulty at the upper end:--

1 In young subjects the higher grades of mental deficiency were overlooked, because the scale caused such subjects to test only a little below nor adult subjects was greatly overestimated, because subjects ere really of the 12- or 13-year e of about 11 years

3 Confusion resulted in efforts to trace the rowth of either feeble-minded or normal children For exae 5-year-old will show an intelligence quotient probably not far froence quotient of about 100; and at 14, an intelligence quotient of about 85 or 90

By such a scale the true border-line case would test approxie 5, 90 I Q (apparently not far below nore 14, 65 I Q (moron deficiency)

On the other hand, re-tests of children by the Stanford revision have been found to yield intelligence quotients almost identical with those secured froraded feeble-raded feeble-e ree, the superior reree[18]

It is unnecessary to eence scale which is equally accurate at all points Absolute perfection in this respect is not claimed for the Stanford revision, but it is believed to be at least free froements
