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.
Most measures of g in humans, including most IQ tests, rely heavily on language and verbal ability, and so they cannot be directly applied to non-human animals. Several alternative measures have been developed to study intelligence in animals, relying on the observation of animals in natural situations or on behavioral tasks in experimental settings.
[1] [2] [3] According to Cattell's psychometrically-based theory, general intelligence (g) is subdivided into g f and g c. Fluid intelligence is the ability to solve novel reasoning problems and is correlated with a number of important skills such as comprehension, problem-solving, and learning. [ 4 ]
g factor may refer to: g factor (psychometrics), a model used to describe the commonality between cognitive ability test results; g-factor (physics), a quantity related to the magnetic moment of an electron, nucleus, or other particle; The g Factor: The Science of Mental Ability, a book by Arthur R. Jensen about the psychometric concept
Since a gyromagnetic factor equal to 2 follows from Dirac's equation, it is a frequent misconception to think that a g-factor 2 is a consequence of relativity; it is not. The factor 2 can be obtained from the linearization of both the Schrödinger equation and the relativistic Klein–Gordon equation (which leads to Dirac's).
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 .

The g Factor: General Intelligence and Its Implications is a book by Christopher Brand, a psychologist and lecturer at the University of Edinburgh. It was published by John Wiley & Sons in the United Kingdom in March 1996. The book was "depublished" by the publishing house on April 17, which cited "deep ethical beliefs" in its decision to ...
Vernon puts emphasis on the g factor in all the mental abilities. He extracted the g factor from an ability test, then found that those remaining content [clarification needed] could be divided into two separate parts. He named those two orthogonal group factors as verbal-educational factor (v:ed) and perceptual-mechanical skill factor (k:m).
