Charles E. Spearman

Charles E. Spearman was a British psychologist best known for his work in intelligence testing. He introduced the concept of "g," or general intelligence, which suggests that a single underlying factor influences various cognitive abilities. Spearman believed that individuals who perform well in one area, such as math or language, tend to excel in others too. This idea led to the development of intelligence tests that measure this general factor, influencing educational and psychological assessments. His work laid the foundation for later theories of intelligence, emphasizing the importance of both general and specific cognitive skills.
