This document discusses several theories of intelligence:
- Gardner's theory of multiple intelligences which identifies eight types of intelligence including linguistic, logical/mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalistic.
- Spearman's two factor theory which distinguishes between general intelligence (g) and specific abilities (s). It also discusses crystallized and fluid intelligence.
- Sternberg's theory of successful intelligence which defines intelligence as the ability to succeed based on one's goals through analytical, creative, and practical abilities.
- Intelligence is also commonly measured as IQ using standardized tests, but IQ is only a snapshot and multiple factors can influence scores.
