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 ...
John Leonard Horn (September 7, 1928 – August 18, 2006) was a scholar, cognitive psychologist and a pioneer in developing theories of intelligence. The Cattell-Horn- Carroll (CHC) theory is the basis for many modern IQ tests.
An influential theory that promoted the idea that IQ measures a fundamental quality possessed by every person is the theory of General Intelligence, or g factor. [27] The g factor is a construct that summarizes the correlations observed between an individual's scores on a range of cognitive tests.
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 ...
Though there were exceptions (e.g., Thorndike), most theories of intelligence included g, a general index of cognitive ability. [ 31 ] [ 32 ] An intelligence theory that has drawn considerable attention is Cattell-Horn-Carroll (CHC), which is grounded in extensive factor analytic research from cognitive ability test databases, as well as ...
The Triarchic Theory of Intelligence or Three Forms of Intelligence, [1] formulated by psychologist Robert Sternberg, aims to go against the psychometric approach to intelligence and take a more cognitive approach, [clarification needed] which leaves it to the category of the cognitive-contextual theories.

Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness.Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason.
The following outline is provided as an overview of and topical guide to human intelligence: Human intelligence is, in the human species , the mental capacities to learn, understand, and reason, including the capacities to comprehend ideas, plan, solve problems, and use language to communicate.
