Charles Edward Spearman

Charles Edward Spearman was a British psychologist known for developing the concept of general intelligence, or "g factor," in the early 20th century. He believed that a common underlying ability influences performance across various intellectual tasks, such as reasoning, memory, and problem-solving. Spearman's work helped shape modern intelligence testing by suggesting that individual differences in mental abilities are connected through this general factor. His findings provided a foundation for understanding cognitive abilities and their interrelationships, influencing psychological assessment and educational practices.
