Since its introduction in the 1890s. IQ as a theoretical concept and as the tested value often become the subject of criticism. Weight issues arising in the course of this debate:
- Which actually stands for IQ, and some of its practical value?
- So valid are these tests and what they measure?
- Are IQ tests culturally biased, ie designed for a certain cultural codes?
Raymond Cattell - known on both sides of the ocean psychologist who has lived a long life, has created a methodology for testing IQ and ranking point factors of this factor, which drew a line under years of discussions about IQ-tests and answered a number of the problems in this debate matters.
Firstly, IQ-test Kettela online contains abstract tasks and measures the level of intellectual development, regardless of culture verbalized factors: language, language constructs, education, etc. Thus, the possibility of expanded Cattell IQ-test: it became possible to apply it not only, for example, in English-speaking cultures, but also in other verbal systems. Cattell test can pass and Russian.
Secondly, Cattell developed the theoretical basis of research and intelligence identified as part of intelligence:
- Agile intellect;
- Crystallized intelligence.
The first type of intelligence is associated with the simultaneous and non-discrete information processing by the right hemisphere of the brain, ie, with the ability to quickly address emerging challenges, regardless of previous experience. The second type of intelligence is associated with sequential processing of information, and is a component of intelligence, acquired mainly in education (teaching).
Theory Cattell suggests that general intelligence is actually a set of perhaps 100 abilities compound which occurs in different people in different ways, which is what makes each person intellectually dissimilar. Theory Cattell shares these abilities into two groups, which have a completely different path of development in the formation of man.
If you pass the test and discuss the results of Cattell IQ testing in points, according to Cattell IQ is divided into the following levels:
above 160 - the level of genius
140 - 159 - a high level of intelligence
120 - 139 - above average intelligence
100 - 119 - average intelligence
90 - 99 - below average intelligence
Regarding the validity of the IQ-test Cattell online researchers have shown that the test has good validity. The test results are statistically significantly correlated with the number of variables associated with intelligence.
