Those who do better on childhood intelligence tests tend to have a lower drop out rate, and complete more years of school and are predictive of school success. [4] For instance, one of the largest ever studies found a correlation of 0.81 between the general intelligence or g-factor and GCSE results. [13]
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 ...
CHC is actually an amalgam of Cattell-Horn Gf-Gc theory and Carroll's three-tier model. [33] proposed a framework with the broadest level a general intelligence factor conceptually similar to Spearman's g. This general factor was divided into eight narrower abilities, each consisting of narrow factors.

The gap of the IQ between white and black students was a subject of debate in the United States, particularly around the 1970s. One view, which is referred to among behavioral geneticists as the genetic position, holds that IQ is determined by hereditary factors - about 80 percent of the variability of intelligence while 20 percent is attributed to environmental factors.

John Leonard Horn (September 7, 1928 – August 18, 2006) was a scholar, cognitive psychologist and a pioneer in developing theories of intelligence. The Cattell-Horn- Carroll (CHC) theory is the basis for many modern IQ tests.
His most significant works were the Mathematico-Deductive Theory of Rote Learning (1940), and Principles of Behavior (1943), which established his analysis of animal learning and conditioning as the dominant learning theory of its time. Hull's model is expressed in biological terms: Organisms suffer deprivation; deprivation creates needs; needs ...
In general, intelligence is thought to be attributed to both genetic and environmental factors, but the extent to which each plays a key role is highly disputed. Studies of identical and non-identical twins raised separately and together show a strong correlation between child IQ and socio-economic level of the parents.
