Johnson, Wendy; Logie, Robert H.; Brockmole, James R. – Intelligence, 2010
Researchers interested in working memory have debated whether it should be considered a single latent cognitive ability or a set of essentially independent latent abilities distinguished by domain-specific memory and/or processing resources. Simultaneously, researchers interested in cognitive aging have established that there are substantial…

Castejon, Juan L.; Perez, Antonio M.; Gilar, Raquel – Intelligence, 2010
This paper compares different theoretical models of the structure of intelligence, based on the analysis of data obtained in a series of measured abilities corresponding to the Spectrum assessment activities (Gardner, Feldman & Krechevsky, 1998) in a sample of 393 children enrolled in kindergarten and first grade. The data were analyzed using…

Vock, Miriam; Holling, Heinz – Intelligence, 2008
The objective of this study is to explore the potential for developing IRT-based working memory scales for assessing specific working memory components in children (8-13 years). These working memory scales should measure cognitive abilities reliably in the upper range of ability distribution as well as in the normal range, and provide a…

Detterman, Douglas K. – Intelligence, 1982
In an argument for orthogonal variables to explain intelligence, higher-order constructs, including "g" as a single thing in intelligence, are suggested to inevitably result from complex systems with interrelated parts. Biological reductionism and other arguments for the higher-order constructs as explanations of intellectual functioning…

Palmer, B.R.; Gignac, G.; Manocha, R.; Stough, C. – Intelligence, 2005
and discussed.There has been some debate recently over the scoring, reliability and factor structure of ability measures of emotional intelligence (EI). This study examined these three psychometric properties with the most recent ability test of EI, the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT V2.0; Mayer, Salovey, & Caruso,…

Kranzler, John H.; Jensen, Arthur R. – Intelligence, 1991
This study investigated whether a unitary elemental process or several independent processes underlie psychometric "g" (factor of general intelligence). Results with 101 college students administered 2 intelligence tests and a large battery of elementary cognitive tasks suggest that as many as 4 independent components make up…

Lim, Tock Keng – Intelligence, 1988
Heim's AH4 Test of General Intelligence, Raven's Advanced Progressive Matrices, and two Piagetian formal operations tests (Shayer's Science Reasoning Tasks and Arlin's Test of Formal Reasoning) were administered to 459 15-year-olds attending Secondary three (grade nine) in Singapore. A hierarchical factor structure was found underlying all of…

Carroll, John B. – Intelligence, 1991
Because they used an inappropriate statistical procedure, J. H. Kranzler and A. R. Jensen (1991) have not demonstrated that a factor of general intelligence ("g") depends on several independent factors. A factorial reanalysis of their data suggests that speed and efficiency of information processing are important in "g." (SLD)

Kranzler, John H.; Jensen, Arthur R. – Intelligence, 1991
The hypothetical idea of a perfectly pure psychometric "g" is empirically unattainable. Because the unity of "g" cannot be proved or disproved by factor analysis, the unitary "g" hypothesis represents a parsimonious assumption. J. B. Carroll's (1991) analysis demonstrates the relationship between psychometric and…

Carroll, John B. – Intelligence, 1991
In their reply to the present author's critique (1991), J. H. Kranzler and A. R. Jensen have still not demonstrated that a factor of general intelligence, "g," depends on, or contains, several independent factors. They have only demonstrated that an estimate of "g" is predictable from several independent components. (SLD)

Carroll, John B.; And Others – Intelligence, 1984
Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…
