Problems with IQ Gains: The Huge Vocabulary Gap
Flynn, James R.
Journal of Psychoeducational Assessment, v28 n5 p412-433 Oct 2010
Despite Kaufman, Raven's Progressive Matrices and the Wechsler subtest Similarities are tests whose gains call for special explanation. The spread of "scientific spectacles" is the key, but its explanatory potential has been exhausted. Three trends force us to look elsewhere: (a) gains on Wechsler subtests such as Picture Arrangement, (b) gains in developed nations persisting into the 21st century, (c) the growing gap between the active vocabularies of parents and their children. (Contains 12 tables and 2 figures.)
