Spatial Working Memory and Neural Efficiency in Mental Rotations: An Insight from Pupillometry
Peer reviewed Peer reviewed
Direct linkDirect link
Buckley, Jeffrey; Canty, Donal; White, David; Seery, Niall; Campbell, Mark – Engineering Design Graphics Journal, 2018
Spatial ability, particularly the cognitive capacity for mental rotations, is a critical component of human cognition. Proficiency with mental rotation tasks is linked with educational performance in various Science, Technology, Engineering, and Mathematics (STEM) disciplines, and with more general tasks such as real world wayfinding. Spatial…

Development and Validity of a Dutch Version of the Remote Associates Task: An Item-Response Theory Approach
Peer reviewed Peer reviewed
Direct linkDirect link
Chermahini, Soghra Akbari; Hickendorff, Marian; Hommel, Bernhard – Thinking Skills and Creativity, 2012
The Remote Associates Test (RAT) developed by Mednick and Mednick (1967) is known as a valid measure of creative convergent thinking. We developed a 30-item version of the RAT in Dutch with high internal consistency (Cronbach's alpha = 0.85) and applied both Classical Test Theory and Item Response Theory (IRT) to provide measures of item…

The Nature of Psychometric "g": Unitary Process or a Number of Independent Processes?
Peer reviewed Peer reviewed
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…

No Demonstration That "g" Is Not Unitary, but There's More to the Story: Comment on Kranzler and Jensen.
Peer reviewed Peer reviewed
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)
