who opposed the two factor theory of intelligence
Two-factor theory of intelligence Charles Spearman developed his two-factor theory of intelligence using factor analysis.[1] His research not only led him to develop the concept of the g factor of general intelligence, but also the s factor of specific intellectual abilities.[2] L. L. Thurstone, Howard Gardner, and Robert Sternberg also researched the structure of intelligence, and in analyzing their data, concluded that a single underlying factor was influencing the general intelligence of individuals. However, Spearman was criticized in 1916 by Godfrey Thomson, who claimed that the evidence was not as crucial as it seemed.[3] Modern research is still expanding this theory by investigating Spearman's law of diminishing returns,[4] and adding connected concepts to the research.[5]
Alfred Binet Alfred Binet (French: [binɛ]; July 8, 1857 – October 18, 1911) was a French psychologist who invented the first practical IQ test, the Binet–Simon test.[2] In 1904, the French Ministry of Education asked psychologist Alfred Binet to devise a method that would determine which students did not learn effectively from regular classroom instruction so they could be given remedial work. Along with his collaborator Théodore Simon, Binet published revisions of his test in 1908 and 1911, the last of which appeared just before his death.
