analytic test used to measure verbal comprehension and analytical thinking. The analogies on the MAT may be either semantic, classification, association, or logical/mathematical. Semantic analogies involve the definitions of the terms involved, and may be divided up into the following groups: synonyms/definitions; antonyms/contrasts; degrees of intensity; or word part and meaning. Classification analogies depend on an understanding of the way words and concepts are placed in a hierarchy. These analogies may have to do with category, membership, or the relation of whole and part. Association analogies are the most common type of analogy; they have to do with the relationship between two ideas. Association analogies may depend on the characteristics of an object, the order of something, or a cause-and-effect relationship. Finally, logical/mathematical analogies may contain equations, fractions, multiples, negation, or letter and sound patterns.
