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]
Philosophy of mind In Western Philosophy, the earliest discussions of dualist ideas are in the writings of Plato who maintained that humans' "intelligence" (a faculty of the mind or soul) could not be identified with, or explained in terms of, their physical body.[6][30] However, the best-known version of dualism is due to René Descartes (1641), and holds that the mind is a non-extended, non-physical substance, a "res cogitans".[7] Descartes was the first to clearly identify the mind with consciousness and self-awareness, and to distinguish this from the brain, which was the seat of intelligence. He was therefore the first to formulate the mind–body problem in the form in which it still exists today.[7]
