ed correctly. The test was located in year XII
of the 1908 scale, and in year XV of the 1911 revision. Goddard and
Kuhlmann retain it in the original location. The Stanford results of
1911, 1912, 1914, and 1915 agree in showing the test too difficult for
year XII, even when only two out of three correct responses are
required. If the original form of the experiment is used, it is
exceedingly difficult for year XV. As here given it fits well at
year XIV.

XIV, 5. ARITHMETICAL REASONING

PROCEDURE. The following problems, printed in clear type, are shown one
at a time to the subject, who reads each problem aloud and (with the
printed problem still before him) finds the answer without the use of
pencil or paper.

(a) _If a man's salary is $20 a week and he spends $14 a week,
how long will it take him to save $300?_
(b) _If 2 pencils cost 5 cents, how many pencils can you buy for
50 cents?_
(c) _At 15 cents a yard, how much will 7 feet of cloth cost?_

Only one minute is allowed for each problem, but nothing is said about
hurrying. While one problem is being solved, the others should be hidden
from view. It is not permissible, if the subject gives an incorrect
answer, to ask him to solve the problem again. The following exception,
however, is made to this rule: If the answer given to the third problem
indicates that the word _yard_ has been read as _feet_, the subject is
asked to read the problem through again carefully (aloud) and to tell
how he solved it. No further help of any kind may be given.

SCORING. _Two of the three_ problems must be solved correctly within the
minute allotted to each. No credit is allowed for correct method if the
answer is wrong.

REMARKS. We have selected these problems from the list used by Bonser in
his _Study of the Reasoning Ability of Children in the Fourth, Fifth,
and Sixth School Grades_.[75]

Our tests of 279 "at age" children between 12 and 15 years reveal the
surprising fact that the test as here used and scored is not passed by
much over half of the children of any age in the grades below the
high-school age. Of the high-school pupils 19 per cent failed to pass,
21 per cent of ordinarily successful business men (!), and 27 per cent
of Knollin's unemployed men testing up to the "average adult" level. To
find average intelligence cutting such a sorry figure raises the
question whether the
