Spearman's theory of intelligence

Spearman's theory of intelligence, known as the "g factor," suggests that general intelligence underlies specific skills and knowledge across various domains, including general knowledge. He posited that individuals possess a core intellectual ability (the g factor) that affects their performance on different cognitive tasks. This means that a person who excels in one area, like solving math problems, is likely to do well in other areas, such as playing music or understanding concepts in science. Essentially, Spearman's theory emphasizes that a single, overarching intelligence influences diverse cognitive abilities and general knowledge.
