There is overwhelming evidence for the existence of substantial genetic influences on
individual differences in general and specific cognitive abilities, especially in adults. The …

Neuroscience is contributing to an understanding of the biological bases of human
intelligence differences. This work is principally being conducted along two empirical fronts …

The genetic influence on the association between contemporaneously measured
intelligence and academic achievement in childhood was examined in nationally …

Measures of intelligence were collected in 209 twin pairs at 5, 7, 10, and 12 years of age, as
part of a longitudinal project on intelligence, brain function, and behavioral problems …

Pedigree-based analyses of intelligence have reported that genetic differences account for
50–80% of the phenotypic variation. For personality traits these effects are smaller, with 34 …

Intelligence, or general cognitive function, is phenotypically and genetically correlated with
many traits, including a wide range of physical, and mental health variables. Education is …

Intelligence is associated with important economic and health-related life outcomes 1.
Despite intelligence having substantial heritability 2 (0.54) and a confirmed polygenic …

Most theories of human mental evolution assume that selection favored higher intelligence
and larger brains, which should have reduced genetic variance in both. However, adult …

It has been known since 1904 that, in humans, diverse cognitive traits are positively
intercorrelated. This forms the basis for the general factor of intelligence (g). Here, we …

Background: Several studies in the new field of cognitive epidemiology have shown that
higher intelligence predicts longer lifespan. This positive correlation might arise from …
