A large number of studies have reported average performance differences in favor of males in mental rotation tasks. However, it is still unclear to what extent the magnitude of the sex differences varies across age, and whether the differences increase with age. In this study, we reanalyzed data from a cross-sectional investigation of N = 1624…

Schweizer, Karl; Moosbrugger, Helfried – Intelligence, 2004
The paper reports on an investigation of attention and working memory as sources of intelligence. The investigation was concentrated on the relatedness of attention and working memory as predictors of intelligence and on the structure underlying the prediction. In a sample of 120 participants, intelligence was assessed by the Advanced Progressive…

Peer reviewedSchweizer, Karl – Intelligence, 2001
Studied the contribution of preattentive processes to the cognitive speed-ability relationship for 80 participants. Results reveal an increase in ability-related variances due to the stimulation of preattentive processes. Coefficients for a structural equation model indicated that preattentive processes exerted a stronger effect on cognitive…

Rindermann, H.; Neubauer, A. C. – Intelligence, 2004
According to mental speed theory of intelligence, the speed of information processing constitutes an important basis for cognitive abilities. However, the question, how mental speed relates to real world criteria, like school, academic, or job performance, is still unanswered. The aim of the study is to test an indirect speed-factor model in…
