General Intelligence refers to the overall cognitive ability of an individual to learn, reason, solve problems, and adapt to new situations. It encompasses various mental capabilities, including memory, comprehension, and logical reasoning. Often measured through standardized tests, general intelligence is thought to reflect a person's potential to perform tasks across different domains. This concept is often associated with the g factor, a term coined by psychologist Charles Spearman in the early 20th century. The g factor suggests that individuals who excel in one area of intelligence are likely to perform well in others, indicating a common underlying cognitive ability.
