For nearly a century, twin and adoption studies have yielded substantial estimates of
heritability for cognitive abilities, although it has proved difficult for genomewide-association …

We conduct a genome-wide association study (GWAS) of educational attainment (EA) in a
sample of~ 3 million individuals and identify 3,952 approximately uncorrelated genome …

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 …

A genome-wide association study (GWAS) of educational attainment was conducted in a
discovery sample of 101,069 individuals and a replication sample of 25,490. Three …

Education, socioeconomic status, and intelligence are commonly used as predictors of
health outcomes, social environment, and mortality. Education and socioeconomic status …

Genome-wide association studies (GWASs) have become the focus of the statistical analysis
of complex traits in humans, successfully shedding light on several aspects of genetic …

General intelligence is an important human quantitative trait that accounts for much of the
variation in diverse cognitive abilities. Individual differences in intelligence are strongly …

Using data from the Philadelphia Neurodevelopmental Cohort, we examined whether
European ancestry predicted cognitive ability over and above both parental socioeconomic …

Very different neurocognitive processes appear to be involved in cognitive abilities such as
verbal and non-verbal ability as compared to learning abilities taught in schools such as …

Multivariate quantitative genetic research suggests a hierarchical model of cognitive abilities
where genetic effects are largely general, cutting across most cognitive abilities. Some …
