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.
Piaget's operativity is considered to be prior to, and ultimately provides the foundation for, everyday learning, [12] much like fluid ability's relation to crystallized intelligence. [86] Piaget's theory also aligns with another psychometric theory, namely the psychometric theory of g, general intelligence. Piaget designed a number of tasks to ...
Gardner's theory of multiple intelligences can be seen as both a departure from and a continuation of the 20th century's work on the subject of human intelligence. Other prominent psychologists whose contributions variously developed or expanded the field of study include Charles Spearman , Louis Thurstone , Edward Thorndike , and Robert ...
Kurt W. Fischer advanced a theory that integrates Piaget's notion of stages in cognitive development with notions from learning theory and skill construction as explained by the cognitive psychology of the 1960s. [19] Fischer's conception of the stages of cognitive development is very similar to that of Case. That is, he describes four major ...
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 ...

The Gesell Development Schedule operates off what is known as an individual's developmental quotient, or otherwise known as DQ.
