There are many tests on the market purporting to measure general intelligence. They are used for a variety of purposes with many differing groups. Examination of them reveals so much diversity in the sorts of items they contain that one wonders how the tests can be measuring the same thing, i.e. general intelligence. Several tests have purported to break general intelligence into a verbal and a numerical factor. The ACE has long yielded such scores. More recently the Wesman PCT has found use in industry as a short intelligence test giving both a verbal and numerical score. Gerken (3), noting frequent disparity of PCT and ACE scores in a group of male college students, undertook a study which showed the relationship between these two tests to be, in fact, fairly low despite the similar nature of the scores claimed by the authors.
