The Culture Fair Intelligence Test (CFIT) was created by Raymond Cattell in 1949 as an attempt to measure cognitive abilities devoid of sociocultural and environmental influences.
[1] Scholars have subsequently concluded that the attempt to construct measures of cognitive abilities devoid of the influences of experiential and cultural conditioning is a challenging one.
Fluid intelligence (Gf) is in several ways more fundamental and is particularly evident in tests requiring responses to novel situations.
Scale I includes eight subtests of mazes, copying symbols, identifying similar drawings and other non-verbal tasks.
The most widely used individual tests of cognitive abilities, such as the current editions of the Wechsler Adult Intelligence Scale and the Stanford–Binet Intelligence Scale,[14] report cognitive ability scores as "deviation IQs" with 15 IQ points corresponding to one standard deviation above or below the mean.
