Howard Gardner is an American psychologist who developed the theory of multiple intelligences. The theory posits that intelligence is not a single general ability but rather consists of at least eight relatively independent faculties or intelligences. Gardner identified eight intelligences: linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalist. Gardner's theory challenged the traditional view that intelligence is a single general ability and that it can be adequately assessed by paper-and-pencil tests. His work has had significant influence on educational practices and theories of learning.
