Abstract

A well-recognized framework for modeling human intelligence centers around Spearman's g, a common central factor accounting for individual differences in cognitive performance across a variety of complex tasks (Spearman 1904). The neural basis of g may be better characterized by posterior-frontal integration, rather than parietal, which may be just one of many posterior regions that are controlled by the prefrontal cortex (PFC).
