Speed Isn't Everything: Complex Processing Speed Measures Mask Individual Differences and Developmental Changes in Executive Control
Peer reviewed Peer reviewed
Direct linkDirect link
Cepeda, Nicholas J.; Blackwell, Katharine A.; Munakata, Yuko – Developmental Science, 2013
The rate at which people process information appears to influence many aspects of cognition across the lifespan. However, many commonly accepted measures of "processing speed" may require goal maintenance, manipulation of information in working memory, and decision-making, blurring the distinction between processing speed and executive…

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)
