J.H. Kranzler and A.R. Jensen report on a reanalysis of previous data that is again inconsistent with the hypothesis that psychometric "g" is unitary. J.B. Carroll reiterates objections to the evidence that Kranzler and Jensen offer in support of a composite "g." (SLD)

The results of studies regarding intelligence in infancy are reviewed, and are compatible with Sternberg's findings on intelligence in adulthood. It is suggested that a major aspect of intelligence--attitude toward and performance with novel kinds of concepts--is continuous in nature throughout the life span, but requires different measurement…

This article presents three studies that were designed to map the dimensions involved in "g," with an emphasis of the place of self-awareness in it. The first study involved preschoolers from 3 to 7 years of age. These were examined in three domains (spatial, quantitative and categorical reasoning) with both actual tasks and tasks addressed to the…

An approach to intelligence which emphasizes domain-specific constraints on knowledge structures is compared to information processing approaches. The evaluation of any cognitive ability as being intelligent crucially depends on prior specification of the formal constraints on the domains of knowledge from which that ability originates.

Jensen (1985) caused us to reexamine earlier findings. After correcting perceptual efficiency and executive systems measures for unreliability, original conclusions remain tenable. Control processes are factors in understanding race-related differences in intelligence. We do not deny the association of "speediness" but argue for a multidimensional…

Two methodological issues involved in determining the relationship between learning and general intelligence were examined: (1) the use of learning strategies in a paired-associate task and (2) the importance of time (rather than errors) in the measurement of learning efficiency. (Author/RD)
