Detailed explanation-1: -It is well-known that individual differences in processing speed predict individual differences in cognitive abilities. Smarter people process information and language more quickly and react faster than less intelligent people (Chiappe & Chiappe, 2007; Jensen, 2006; Sheppard & Vernon, 2008).
Detailed explanation-2: -A large number of studies have been conducted with uniformly positive correlations, leading to the generally safe conclusion that larger brains predict greater intelligence. In healthy adults, the correlation of total brain volume and IQ is approximately 0.4 when high quality tests are used.
Detailed explanation-3: -IQ correlates positively with family income, socioeconomic status, school and occupational performance, military training assignments, law-abidingness, healthful habits, illness, and morality.
Detailed explanation-4: -The network neuroscience theory proposes that crystallized intelligence engages highly accessible representations of prior knowledge and experience and relies on easy-to-reach network states. In contrast, fluid intelligence reflects the capacity to solve novel problems and to demonstrate adaptive, flexible behavior.
