Major, Jason T.; Johnson, Wendy; Deary, Ian J. – Intelligence, 2012
Three prominent theories of intelligence, the Cattell-Horn-Carroll (CHC), extended fluid-crystallized (Gf-Gc) and verbal-perceptual-image rotation (VPR) theories, provide differing descriptions of the structure of intelligence (McGrew, 2009; Horn & Blankson, 2005; Johnson & Bouchard, 2005b). To compare these theories, models representing them were…

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…

Lakin, Joni M.; Gambrell, James L. – Intelligence, 2012
Measures of broad fluid abilities including verbal, quantitative, and figural reasoning are commonly used in the K-12 school context for a variety of purposes. However, differentiation of these domains is difficult for young children (grades K-2) who lack basic linguistic and mathematical literacy. This study examined the latent factor structure…

Reynolds, Matthew R.; Keith, Timothy Z. – Intelligence, 2007
Spearman's "law of diminishing returns" or SLODR refers to a decrease in "g" saturation as ability level increases. SLODR has been demonstrated in a number of intellectual batteries but several important aspects of the phenomenon are not yet well understood. We investigated the presence of SLODR in the Kaufman Assessment…

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…

Stankov, Lazar – Intelligence, 1980
Cluster analysis, applied to Carroll's cognitive theory, indicates that the obtained clusters make intuitive sense and imply that taxonomy is possible. Moreover, some clusters are similar to those suggested by other theories, especially the theory of fluid and crystallized intelligence. (Author/CP)

Gignac, Gilles; Vernon, Philip A. – Intelligence, 2003
Created an adaptation of the Digit Symbol subtest of the Wechsler Adult Intelligence Scale, the Digit Symbol Rotation test, and evaluated its "g" loading with 54 adults. Results suggest the Digit Symbol Rotation test has more factorial validity than Digit Symbol, but remains equally easy to administer and score. (SLD)

Bickley, Patricia G.; And Others – Intelligence, 1995
A three-stratum theory of intelligence was tested using hierarchical confirmatory factor analysis with the LISREL computer program. Results from subsamples of a group of 6,359 participants aged 2 to 90 years supported the 3-stratum theory, but did not support developmental changes in the organization of cognitive abilities. (SLD)

Gustafsson, Jan-Eric. – Intelligence, 1984
This study was designed to test the reliability of five major models of the structure of cognitive abilities. A battery of 16 tests was administered to 1000 Swedish sixth graders. Based on the results, a three-level hierarchical LISREL-based model (the HILI-model) is suggested. (Author/EGS)

Horn, John L. – Intelligence, 1980
This article summarizes results from studies of the organization and development of cognitive abilities in adults aged 20 to 60 years old. Theories of intelligence stipulating a hierarchy of intellectual functions, with fluid and crystallized intelligence at the top, are supported. Six conclusions on age differences are offered. (Author/RD)

Danthiir, Vanessa; Wilhelm, Oliver; Schulze, Ralf; Roberts, Richard D. – Intelligence, 2005
This study explored the structure of elementary cognitive tasks (ECTs) and relations between the corresponding construct(s) with processing speed (Gs) and fluid intelligence (Gf). Participants (N=321) completed 14 ECTs, 3 Gs, and 6 Gf marker tests, all administered in paper-and-pencil format to reduce potential confounds evident when tasks are…

Dunst, Carl J. – Intelligence, 1978
An historical overview of investigations concerned with delineating the structure and composition of infant intellectual activity is presented. Earlier conceptualizations characterized infant intelligence as a unitary trait or factor. Recent studies contend that infant intellectual activity is comprised of varied sets of relatively independent…

Inman, William C.; Secrest, Barbara T. – Intelligence, 1981
A hierarchical factor solution was obtained from a psychometrized battery of Piagetian-type tasks individually administered to 660 kindergarten children. The first two levels of factors included Piagetian theoretical entities. A third level factor was identified as a g. The association of Piagetian tasks with academic achievement was through the g…

Yang, Shih-Ying; Sternberg, Robert J. – Intelligence, 1997
The conceptions of intelligence of Taiwanese Chinese were investigated in two studies involving 68 and 434 participants (college students and community adults). Five factors emerged in the second study for ratings of frequency of characteristics of intelligence identified in the first study, and four factors emerged from ratings of importance of…

Barnes, G. Michael – Intelligence, 1978
Creativity, intelligence, and problem-solving tasks that varied in the explicitness of problem definition and in the format for an acceptable solution were administered to 100 college students. Two hypotheses that distinguished between concepts of creative and intelligent problem-solving were presented, and syntactical and strategic distinctions…
