The G factor can be measured by an IQ test 2. The G factor is a good indication of school performance Disadvantages/weakness of Charles Spearman’s theory: 1. The backlash and criticism regarding how the G factor only measures General Intelligence 2. The G factor doesn’t take into Topic: Charles Spearman's General Intelligence Theory Blog Link: https://musheerhz.blogspot.com/2019/03/charles-spearman-theory-of-intelligence.html?m=0 Assi Charles Spearman was the first to postulate that there exists a single general factor of human intelligence, something that reflects positive correlations among different cognitive tasks. Spearman coined the term “ g factor” [ 1 ]. 2014-11-17 Charles Spearman and the Discovery of the g Factor Charles Spearman (1863-1945) is the author of the empirical validation of Galton’s intuitions.

Spearman’s Two-Factor Theory: The English psychologist, Charles Spearman (1863-1945), in 1904 proposed his theory of intelligence called two-factor theory. According to him intellectual abilities are comprised of two factors, namely the general ability known as G-factor and specific Abilities known as S-factors. Spearman derived this theoretical entity, called the general factor, or simply g, through a new statistical technique that analyzed the correlations among a set of variables. This technique, called factor analysis, demonstrated that scores on all mental tests are positively correlated; this offered compelling evidence that all intelligent behavior is derived from one metaphorical pool of mental energy.

Spearman stayed and taught at University College, London until he retired in 1931. He obtained the entitlement of professor of psychology in 1928 when a separate department of psychology was created at the university. His most influential g factor theory served as a stepping stone for intelligence theories. That's why, in addition to coining the term Factor G, Spearman devised a strategy in parallel to arrive empirically at specific values that defined it.

He observed that children's performance ratings, across seemingly unrelated school subjects, were positively correlated , and reasoned that these correlations reflected the influence of an underlying general mental ability that entered into performance on all kinds of mental tests. Spearman identified what he called the “g” of intelligence. This G-factor would become the general intelligence that a person had. This means anyone who can perform well on one test should be able to perform well on other tests because of their generalized intelligence. This means that the G-factor can also be measured. An intelligence quotient score from an IQ test would be a reflection of this capability. Psychologist Charles Spearman helped develop a statistical technique known as factor analysis, which allows researchers to use a number of different test items to measure common abilities.

Charles Spearman tog tidigt fram en tvåfaktor-teori (g-faktor-teori) gällande Nivå 3 består av grupper av test och kallas first-order factors och summan av en. Bra start för en djupare förståelse av intelligenstestning är ”The g factor: the science of mental ability”, skriven av Arthur Jensen.

Factor G y Factor S 2007-09-10 However, later Spearman introduced group factor that was particular to those correlations that were not a result of factor g or s. His ideas were in 1938 criticized on paper by psychologist Louis L. Thurstone who argued his own experiments showed that intelligence formed seven primary categories: numerical, reasoning, spatial, perceptual, memory, verbal fluency and verbal comprehension.
