The Cattell Culture Fair Intelligence Test (like the Raven's Progressive Matrices) is not completely free from the influence of culture and learning. [7] Some high-IQ societies , such as The Triple Nine Society , accept high scores on the CFIT-III as one of a variety of old and new tests for admission to the society.
The Cattell Infant Intelligence Scale was considered particularly impactful because of its younger age range, short administration time, and easy scoring methods. [10] Cattell implemented significant changes to the test by taking into account the use of objects which may be influenced by home life, and removing them from the test in order to ...
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 ...
Cattell constructed a number of ability tests, including the Comprehensive Ability Battery (CAB) that provides measures of 20 primary abilities, [32] and the Culture Fair Intelligence Test (CFIT) which was designed to provide a completely non-verbal measure of intelligence like that now seen in the Raven's. The Culture Fair Intelligence Scales ...
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 degree to which intelligence test scores can be linked to genetic heritability increases with age. There is presently no explanation for this puzzling result, but flaws in the testing methods are suspected. A study of Dutch twins concludes that intelligence of 5 year olds is 26% heritable, while the test scores of 12-year-olds is 64% heritable.
The modern theories of intelligence began to emerge along with experimental psychology. This is when much of psychology was moving from philosophical to more biology and medical science basis. In 1890, James Cattell published what some consider the first "mental test". Cattell was more focused on heredity rather than environment.
His discovery was confirmed later by many other studies. While trying to understand these remarkable test score increases, Flynn had postulated in 1987 that "IQ tests do not measure intelligence but rather a correlate with a weak causal link to intelligence". [135] [136] By 2009, however, Flynn felt that the IQ test score changes are real. He ...
