How many types of intelligence did Howard Gardner develop in his theory?

Howard Gardner developed a theory of multiple intelligences, which identifies eight distinct types of intelligence. This theory proposes that traditional measures of intelligence, such as IQ tests, do not encompass the full range of human cognitive abilities. The eight intelligences identified by Gardner include linguistic, logical-mathematical, spatial, musical, bodily-kinesthetic, interpersonal, intrapersonal, and naturalistic intelligence. Each type represents different ways that individuals process information and perceive the world around them, highlighting that intelligence is not a single entity but rather a spectrum of abilities. This framework has broadened the understanding of intellectual capacity and the diverse talents people can possess, making it a pivotal contribution to developmental psychology and educational practices.
