The Cattell–Horn–Carroll theory is an integration of two previously established theoretical models of intelligence: the theory of fluid and crystallized intelligence (Gf-Gc) (Cattell, 1941; Horn 1965), and Carroll's three-stratum theory (1993), a hierarchical, three-stratum model of intelligence. Due to substantial similarities between the ...
The Woodcock–Johnson Tests of Cognitive Abilities is a set of intelligence tests first developed in 1977 by Richard Woodcock and Mary E. Bonner Johnson (although Johnson's contribution is disputed). [1] It was revised in 1989, again in 2001, and most recently in 2014; this last version is commonly referred to as the WJ IV. [2]
Cattell proposed that general intelligence (g) comprises both fluid intelligence (Gf) and crystallized intelligence (Gc). [3] [4] Whereas Gf is biologically and constitutionally based, Gc is the actual level of a person's cognitive functioning, based on the augmentation of Gf through sociocultural and experiential learning (including formal ...
In 1958, Wechsler published another edition of his book Measurement and Appraisal of Adult Intelligence. He revised his chapter on the topic of IQ classification and commented that "mental age" scores were not a more valid way to score intelligence tests than IQ scores. [69] He continued to use the same classification terms.
CHC is actually an amalgam of Cattell-Horn Gf-Gc theory and Carroll's three-tier model. [33] proposed a framework with the broadest level a general intelligence factor conceptually similar to Spearman's g. This general factor was divided into eight narrower abilities, each consisting of narrow factors.
According to theory, individuals who believe their intelligence can grow think about information in their world differently even outside of academic challenges, seen by use of a different heuristic when making judgments of learning (JOLs), or estimates of learning. Those with entity views are generally guided by the principle "easily learned ...

Lewis M. Terman, a psychologist at Stanford University, was one of the first to create a version of the test for people in the United States, naming the first localized version the Stanford revision of the Binet-Simon Intelligence Scale (1916) and the second version the Stanford–Binet Intelligence Scale (1937).
