Improvement of feeble-minded girls over sixteen years of age (K. Harris, Contributor)

Abstract

Comparison of (1) Binet retests on a group of 25 girls who had been formed into a reading club (IQ's ranging from 53-85, median 68) and a control group of 10 non-club girls, with (2) original test results, points out that improvement in IQ is possible after the age of 16 years through training in reading and book work, even in feeble-minded cases, but such improvement seems to be due to changes in vocabulary score and understanding of language rather than to changes in memory span or reasoning ability.
