spearman
charles spearman developed his two-factor theory of intelligence using factor analysis. 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. 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. modern research is still expanding this theory by investigating spearman's law of diminishing returns, and adding connected concepts to the research.
two-factor theory of intelligence
research has been adapted to incorporate modern psychological topics into spearman's two factor theory of intelligence. nature versus nurture is one topic that has been cross studied with spearman's "g" factor. research shows that although environmental factors influence the "g" factor differently, it has been found that it is affected if influenced early in life, rather than adulthood where there is little to no impact. genetic influence has been documented to greatly influence "g" factor on intelligence.
