MULTIPLE INTELLIGENCES First introduced by Harvard psychologist Howard Gardne r in his 1983 book Frames of Mind: The Theory of Multiple Intelligences, the theory suggests that people may possess different forms of intelligence. According to Gardner’s theory, there are eight different intelligences: linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalistic. Each of these intelligences represents a unique way of processing information and solving problems.
