Cattell Culture Fair Intelligence Test

Cultural and age differences

Crystallized intelligence (Gc) refers to that aspect of cognition in which initial intelligent judgments have become crystallized as habits. Fluid intelligence (Gf) is in several ways more fundamental and is particularly evident in tests requiring responses to novel situations. Before biological maturity individual differences between Gf and Gc will be mainly a function of differences in cultural opportunity and interest. Among adults, however, these discrepancies will also reflect differences with increasing age because the gap between Gc and Gf will tend to increase with experience which raises Gc, whereas Gf gradually declines as a result of declining brain function.

Question items

The Culture Fair tests consist of three scales with non-verbal visual puzzles. Scale I includes eight subtests of mazes, copying symbols, identifying similar drawings and other non-verbal tasks. Both Scales II and III consist of four subtests that include completing a sequence of drawings, a classification subtest where respondents pick a drawing that is different from other drawings, a matrix subtest that involves completing a matrix of patterns, and a conditions subtest which involves which, out of several geometric designs, fulfills a specific given condition.

Current use

The Cattell Culture Fair Intelligence Test (like the Raven's Progressive Matrices) is not completely free from the influence of culture and learning. 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. A combined minimum raw score of 85 on Forms A and B is required for admission. The tests are used by many including Mensa and Intertel, which offer a place in their society to anyone scoring in the top 2% and in the top 1% IQ scores respectively.

Validity

Direct concept validity

Direct concept validity (sometimes called construct validity) refers to the degree to which a certain scale correlates with the concept or construct (i.e., source trait) which it purports to measure. Concept validity is thus measured by correlating the scale with the pure factor and this can only be carried out by performing a methodologically sound factor analysis. The relatively high loading of the Culture Fair Intelligence Test on the fluid intelligence factor indicates that the CFIT does, in fact, have a reasonably high direct concept validity with respect to the concept of fluid intelligence. The Culture Fair Intelligence Test was found to load more highly on a "General Intelligence" factor than on an "Achievement" factor, which is consistent with the concept that the CFIT is a measure of "fluid" rather than "crystallized" intelligence.

Convergent validity

Convergent Validity is the extent to which the Culture Fair Intelligence Test correlates with other tests of intelligence, achievement, and aptitude. The intercorrelations between the Culture Fair Intelligence Test and some other intelligence tests have been reported, as shown in the Table below.
