The g factor [a] is a construct developed in psychometric investigations of cognitive abilities and human intelligence.It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks.
Both have been proposed as easily accessible models for studying g. [2] [13] The g factor loadings in Long-Evans rats has been shown to range from .43 to as high as .70 in cognitive ability tasks. [14] In mice, about 55–60% of the individual variance in tests of cognitive ability can be explained by g. [15] [16]
Spearman found that a single common factor explained the positive correlations among tests. Spearman named it g for "general intelligence factor". He interpreted it as the core of human intelligence that, to a larger or smaller degree, influences success in all cognitive tasks and thereby creates the positive manifold. This interpretation of g ...
Gc tasks include problem solving with familiar materials and culture-fair tests of general knowledge and vocabulary. [citation needed] Gf and Gc are both factors of g (general intelligence). Though distinct, there is interaction, as fluid intelligence is a determining factor in the speed with which crystallised knowledge is accumulated (Cattell ...
The spin magnetic moment of a charged, spin-1/2 particle that does not possess any internal structure (a Dirac particle) is given by [1] =, where μ is the spin magnetic moment of the particle, g is the g-factor of the particle, e is the elementary charge, m is the mass of the particle, and S is the spin angular momentum of the particle (with magnitude ħ/2 for Dirac particles).
The concepts of fluid intelligence (g f) and crystallized intelligence (g c) were introduced in 1943 by the psychologist Raymond Cattell. [ 1 ] [ 2 ] [ 3 ] According to Cattell's psychometrically -based theory, general intelligence ( g ) is subdivided into g f and g c .
The 20 g centrifuge at the NASA Ames Research Center. High-g training is done by aviators and astronauts who are subject to high levels of acceleration ('g'). It is designed to prevent a g-induced loss of consciousness (g-LOC), a situation when the action of g-forces moves the blood away from the brain to the extent that consciousness is lost.
This study investigates how g test scores will most likely decrease as g increases. [4] Research has been done to investigate if g scores are made up of scores from Differential Ability Scales , s factors, and how the law of diminishing returns compare to Spearman's Law of diminishing returns .
