The concepts of fluid intelligence (g f) and crystallized intelligence (g c) were introduced in 1943 by the psychologist Raymond Cattell. [ 1 ] [ 2 ] [ 3 ] According to Cattell's psychometrically -based theory, general intelligence ( g ) is subdivided into g f and g c .
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 ...
For his PhD research at the University of Illinois Urbana-Champaign, Horn identified other broad intellectual abilities to supplement fluid reasoning ability (g f) and crystallized ability (g c) postulated by his supervisor Raymond Cattell. As with Cattell, Horn rejected the existence of an even higher level factor of general intelligence ‘g ...
There are two types of intelligence: crystallized intelligence and fluid intelligence. Crystallized intelligence is your ability to utilize information, skills, and experience already learned ...
In the cognitive abilities domain, Cattell researched a wide range of abilities, but is best known for the distinction between fluid and crystallized intelligence. [20] He distinguished between the abstract, adaptive, biologically-influenced cognitive abilities that he called "fluid intelligence" and the applied, experience-based and learning ...
The distinction between fluid and crystallized intelligence can only emerge to the extent that it is possible to develop a battery of tests that accurately distinguishes between material to which test takers should have been exposed and tasks that they should find novel." (Johnson & Bouchard, 2005) [2]
The three-stratum theory is derived primarily from Spearman's (1927) [3] model of general intelligence and Horn & Cattell's (1966) [4] theory of fluid and crystallized intelligence. Carroll's model was also heavily influenced by the 1976 edition of the ETS standard kit. [ 5 ]
Vernon's model about intelligence looks similar to the fluid-crystallized (Gf-Gc) intelligence theory because they both agree with g factor and have two more different dimensions on intelligence structure. In fact, Gf-Gc model has more broad factors such as special visualization (Gv), retrieval (Gr) or speed factor (Gs).
