Peer reviewed Peer reviewed
Direct linkDirect link
Oberauer, Klaus; Sub, Heinz-Martin; Wilhelm, Oliver; Wittmann, Werner W. – Intelligence, 2008
Investigates the relationship between three factors of working memory (storage and processing, relational integration, and supervision) and four factors of intelligence (reasoning, speed, memory, and creativity) using structural equation models. Relational integration predicted reasoning ability at least as well as the storage-and-processing…

Does Test Anxiety Induce Measurement Bias in Cognitive Ability Tests?
Peer reviewed Peer reviewed
Direct linkDirect link
Reeve, Charlie L.; Bonaccio, Silvia – Intelligence, 2008
Although test anxiety is typically negatively related to performance on cognitive ability tests, little research has systematically investigated whether differences in test anxiety result in measurement bias on cognitive ability tests. The current paper uses a structural equation modeling technique to explicitly test for measurement bias due to…

A Note on Sex Differences in Mental Rotation in Different Age Groups
Peer reviewed Peer reviewed
Direct linkDirect link
Geiser, Christian; Lehmann, Wolfgang; Eid, Michael – Intelligence, 2008
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…

Sex Differences in Latent Cognitive Abilities Ages 6 to 59: Evidence from the Woodcock-Johnson III Tests of Cognitive Abilities
Peer reviewed Peer reviewed
Direct linkDirect link
Keith, Timothy Z.; Reynolds, Matthew R.; Patel, Puja G.; Ridley, Kristen P. – Intelligence, 2008
Sex differences in the latent general and broad cognitive abilities underlying the Woodcock-Johnson Tests of Cognitive Abilities were investigated for children, youth, and adults ages 6 through 59. A developmental, multiple indicator-multiple cause, structural equation model was used to investigate sex differences in latent cognitive abilities as…

Differentiation of Cognitive Abilities as a Function of Neuroticism Level: A Measurement Equivalence/Invariance Analysis
Peer reviewed Peer reviewed
Direct linkDirect link
Bonaccio, Silvia; Reeve, Charlie L. – Intelligence, 2006
This paper investigates the differentiation of cognitive abilities as a function of neuroticism. Specifically, we examine Eysenck and White's [Eysenck, H. J., and White, P. O. (1964). Personality and the measurement of intelligence. British Journal of Educational Psychology, 24, 197-201.] hypothesis that cognitive abilities are less differentiated…
