Flores-Mendoza, Carmen; Widaman, Keith F.; Rindermann, Heiner; Primi, Ricardo; Mansur-Alves, Marcela; Pena, Carla Couto – Intelligence, 2013
Sex differences on the Attention Test (AC), the Raven's Standard Progressive Matrices (SPM), and the Brazilian Cognitive Battery (BPR5), were investigated using four large samples (total N=6780), residing in the states of Minas Gerais and Sao Paulo. The majority of samples used, which were obtained from educational settings, could be considered a…

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…

Steinmayr, Ricarda; Beauducel, Andre; Spinath, Birgit – Intelligence, 2010
Recently, different methodological approaches have been discussed as an explanation for inconsistencies in studies investigating sex differences in different intelligences. The present study investigates sex differences in manifest sum scores, factor score estimates, and latent verbal, numerical, figural intelligence, as well as fluid and…

Dykiert, Dominika; Gale, Catharine R.; Deary, Ian J. – Intelligence, 2009
This study investigated the possibility that apparent sex differences in IQ are at least partly created by the degree of sample restriction from the baseline population. We used a nationally representative sample, the 1970 British Cohort Study. Sample sizes varied from 6518 to 11,389 between data-collection sweeps. Principal components analysis of…

Vigneau, Francois; Bors, Douglas A. – Intelligence, 2008
Various taxonomies of Raven's Advanced Progressive Matrices (APM) items have been proposed in the literature to account for performance on the test. In the present article, three such taxonomies based on information processing, namely Carpenter, Just and Shell's [Carpenter, P.A., Just, M.A., & Shell, P., (1990). What one intelligence test…

Lynn, Richard; Allik, Juri; Irwing, Paul – Intelligence, 2004
Raven's Standard Progressive Matrices (SPM) was administered to a sample of 2735 12- to 18-year-olds in Estonia. Both a scree test and the consistent Akaike information criterion (CAIC) indicated the presence of three significant factors. Exploratory and confirmatory factor analysis showed the loadings of the items on the three factors, which were…

Furnham, Adrian; Bunclark, Katherine – Intelligence, 2006
In this study 141 British parents estimated their own, and one of their children's IQ on their overall intelligence as well as on Gardner's (1983) [Gardner, H. (1983). "Frames of the mind: The theory of multiple intelligences." New York: Basic Books.] seven multiple ''intelligences''. Replicating previous studies, fathers gave higher…
