Two cases showing marked change in i.q

Abstract

Two cases are given as typical ones where the I.Q. changed. In one case the case was 9 years, mental age 8-4; and upon second examination 9-4 and 9-9 years. Thus the I.Q. was 92 and later 104. The second case was 6-8, mental age 7-6 with an I.Q. of 112 and the second examination when the child was 6-11 showed a mental age of 9-8 or I.Q. 140. From Psych Bulletin 18:08:00512.
