The construct validity of written Ideaphoria and oral Ideaphoria is discussed through analysis of their content and format and their correlations with tests of divergent thinking and writing speed. The current status of research on the measurement of divergent thinking ability is reviewed. Although the Ideaphoria tests have the same content as…

An experimental test battery designed to measure several perceptual abilities was administered to 1,368 (51.8% male) paying clients of the Johnson O'Connor Research Foundation (JOCRF) in an effort to identify and measure three perceptual abilities: (1) flexibility of closure; (2) speed of closure; and (3) spatial scanning.

The Micro-TOWER system of work sample tests measures the major aptitudes required for most semi-skilled and unskilled occupations. It may be used as a screening…
