1. The document discusses recent research on how executive functions fit within the Cattell-Horn-Carroll (CHC) theory of cognitive abilities and their relationship to general intelligence (g).
2. Studies have found that white matter integrity, processing speed (Gt), and executive functions are strongly related to general fluid intelligence (Gf) and that processing speed may mediate the relationship between white matter integrity and intelligence.
3. The Parietal-Frontal Integration Theory (P-FIT) model proposes that the frontal and parietal lobes are important for constructs like working memory, attention, and executive functions that relate to general intelligence.
