Introductory note by L. M. Terman.-During the last five years, several students of educational psychology at Stanford University have made minor studies of the educability of children testing at various degrees below normal. One of these studies, the results of which are not yet ready for publication, involved a year of tutoring, two to three hours daily, of an 18-year-old girl of about 70 IQ. The study was made by Mrs. Gertrude Bell, a professor in the San Diego State Teachers College. Mrs.

The purposes of the study were: (1) to find out how much the subject's school achievement could be improved, as measured by elaborate educational tests taken before and after treatment; and (2) to find out whether such intensive educational treatment would affect the IQ. The net results of the experiment showed a large improvement in subject matter achievement, amounting on the average to nearly two grades advance for the year. On the other hand, the IQ showed no change except for the slight improvement which would be expected to result from several repetitions of the test. Even specific coaching on types of material analogous to (but not identical with) that composing the Stanford-Binet scale had only negligible effect on the IQ. The present study, by Miss Laura Reiner, is considerably less extensive than that of Mrs. Bell, but it is offered for publication because of the scarcity of carefully made and accurately reported observations on individual cases of low IQ. Although not all subnormal children of a given IQ show the same degree of inability to master school subject matter, the case described in this article gives a concrete and fairly accurate indication of what may be expected educationally, from the typical 8-year-old having 6-year intelligence. Incidently, it gives a rather vivid picture of the differences between 100 IQ and 70 or 75 IQ. We need similar comparisons, even more searching, of the differences between 100 IQ and 140 IQ or higher. jjg: LEWIS M. TEBMAN. 160
