TL;DR: In this paper, the authors analyzed if working memory is especially important to understand g, which comprises the functions of focusing attention, conscious rehearsal, and transformation and mental manipulation of information, while g reflects the component variance that is common to all tests of ability.

TL;DR: The observed findings support an integrative framework for understanding the architecture of general intelligence and executive function, supporting their reliance upon a shared fronto-parietal network for the integration and control of cognitive representations and making specific recommendations for the application of the Wechsler Adult Intelligence Scale and Delis-Kaplan Executive Function System to the study of high-level cognition in health and disease.

TL;DR: In this article, the authors consider concurrently simple short-term storage, mental speed, updating, and the control of attention along with working memory and intelligence measures, across three separate studies.

TL;DR: It is suggested that general intelligence draws on connections between regions that integrate verbal, visuospatial, working memory, and executive processes to reflect the combined performance of brain systems involved in cognitive tasks or draws on specialized systems mediating their interactions.

TL;DR: In this paper, regional brain volumes associated with intelligence were investigated by means of structural magnetic resonance imaging and voxel-based morphometry, and it was shown that increasing g-involvement of individual tests was associated with increased gray matter volume throughout the brain.
