Addresses the theoretically important question of whether g is merely an artifact of the method of constructing psychometric tests and the mathematical operations of factor analysis or whether it has an authentic claim to represent some natural phenomenon that exists independently of psychometrics and factor analysis. (Author/ABB)

The first eight chapters of this book introduce the topic of test bias. The basic issues involved in criticisms of mental tests and arguments about test bias include: (1) variety of tests and test items; (2) scaling of scores and the form of the distribution of abilities in the population; (3) quantification of subpopulation differences; (4)…

This paper summarizes empirical findings of research on a theory of general mental ability, based on laboratory studies of the relationship between measurements of individual differences on conventional psychometric tests and in speed and efficiency of information processes. The paper covers characteristics of "g" (general mental ability),…
