LOGIC-BASED MEASUREMENT OF VERBAL REASONING: A KEY TO INCREASED VALIDITY AND ECONOMY

The purpose of this paper is to define logic-based measurement as a method of measurement in which all measures (test items) are constructed according to the applicable inferential formulae of logic. Such a method of test construction brings into verbal reasoning tests the inferential objectivity of numerical reasoning tests. The availability of such a technology has powerful implications in personnel selection regarding real-life prediction of inferential performance, the legal defensibility of personnel selection tests, the design of economical, inferentially nonredundant tests, and the design of test taxonomies in which basic inferential processes can be thoroughly sampled. These implications are discussed in this paper. Also the paper includes a discussion of the linkage of logic-based measurement with other recently developed technologies such as validity generalization and computer-tailored testing.
