A theory proposed by Howard Gardner that suggests there are many types of intelligences, such as linguistic, logical-mathematical, spatial, etc.
Primary Mental Abilities Test (PMAT): A test developed by Thurstone to measure his seven identified abilities including verbal comprehension, reasoning, perceptual speed etc.
