The concept of intelligence

Abstract

The changing conception of intelligence from 1890 to date is traced. It is concluded that "the emphasis upon group factors as the components of 'intelligence' may be regarded, it seems, essentially as an intermediate position between the extremes suggested at the beginning of the century by Spearman and Thorndike and defended by them respectively throughout the years. (The emphasis upon group factors) is the most significant development of the present period." (PsycINFO Database Record (c) 2006 APA, all rights reserved). © 1938 American Psychological Association.
