Cattell Culture Fair III

From Wikipedia, the free encyclopedia
Jump to: navigation, search

The CFIT or Culture Fair Intelligence Test was developed by Raymond B. Cattell in an attempt to produce an IQ test that accurately estimated intelligence irrespective of environmental factors.[1] Scholars have subsequently concluded that this attempt was not wholly successful.[2] Cattell argued after developing the test that general intelligence (g) consists of fluid intelligence and crystallized intelligence.

Unlike the most widely used IQ tests, such as the current editions of the Wechsler and Stanford-Binet tests,[3] which report IQ scores as "deviation IQs" with 15 IQ points corresponding to one standard deviation above or below the norming sample median, Cattell used a deviation of 24. This means about 68.2 percent of test-takers would have scores between 76 and 124 for as long as the norms were representative, compared to scoring between 85 and 115 on most current tests.[4]

Development[edit]

Raymond Cattell developed his Culture Fair test in the 1940s to study intelligence across the cultures of "civilized countries." In the process of developing the test, he also developed his now widely accepted theory that human intelligence, rather than having the structure of a general factor and many specific factors as proposed by Charles Spearman, has two discernable group factors, "fluid intelligence" and "crystallized intelligence."[5]

Cultural and age differences[edit]

See also: CHC_Theory

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 shows in tests requiring responses to entirely new 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 in age because the gap between gc and gf will tend to increase with experience which raises gc (whereas it has been shown that with increase in age some decay of gf occurs).

Current use[edit]

The Cattell Culture Fair test is now little used because it did not achieve the goal of being free from the influence of culture on learners.[6] Some high-IQ societies, for example The Triple Nine Society, accept the CFIT-III as one of a variety of old and new tests for admission to the society. A combined raw score of 85 on forms A and B is required for admission.[7]

Validity[edit]

Direct concept validity[edit]

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 factor analysis. The relatively high loading of the Culture Fair Intelligence scale on the fluid intelligence factor indicates that the Culture Fair scale does, in fact, have a reasonably high direct concept validity with respect to the concept of fluid intelligence.

The Culture Fair intelligence measure loaded higher on the "General Intelligence" factor than it did on the "Achievement" factor, which is consistent with the concept of the CFIT's being a measure of "fluid" rather than "crystallized" intelligence.[8]

Convergent validity[edit]

Convergent Validity is the extent to which the Culture fair test correlates with other tests of intelligence, achievement, and aptitude. Downing et al. (1965) obtained the relationships between the Culture Fair Intelligence Test and other intelligence tests.

'average' intelligence, that is the median level of performance on an intelligence test, receives a score of 100, and other scores are assigned so that the scores are distributed normally about 100, with a standard deviation of 15. Some of the implications are that: 1. Approximately two-thirds of all scores lie between 85 and 115. 2. Five percent (1/20) of all scores are above 125, and one percent (1/100) are above 135. Similarly, five percent are below 75 and one percent below 65.

Raymond Cattell (1940) argued many years ago for efforts to develop culture free/fair tests because of the lack of portability of tests across different cultures. He led the way in attempting to define and develop tests where the effects of cultural and linguistic differences could be parsed out. However, this is a daunting task as pointed out by Wicherts et al. (2010) where tests such as the Raven's matrices, considered by many to be a nonverbal tests of spatial reasoning and not particularly impacted by culture etc., do not necessarily function as a measure of intelligence in sub-Saharan Africa.  Castles, Elaine E.

Behavior that members of one cultural group view as intelligent might well be perceived by members of another as foolish, misguided, or even antisocial. And so, as testing expert Alexander Wesman pointed out as early as 1968, the 'ingenious mining methods' that cross-cultural investigators have used in their attempts to discover 'the "native intelligence" [that] lies buried in pure form deep in the individual' are in fact 'not ingenious, but ingenuous.'

Since the earliest days of mental testing, psychologists have struggled with the problem of accounting for differences in opportunity to learn, especially those differences moderated by exposure to the language of testing. ... The use of culture-and language-reduced or so-called 'nonverbal' tests stretches from the form boards of Itard through Army Beta to the performance battery of the Wechsler scales, the Progrssive Matrices test (Raven, 1938), the Nonverbal Battery of the Cognitive Abilities Test (Thorndike & Hagen, 1963), and the Universal Nonverbal Intelligence Test (Bracken & McCallum, 1998). The most important disadvantage of this approach is that the abilities measured by nonverbal tests—especially those that use only figural reasoning items—under-represent the construct of intelligence.
