Multivariate genetic research suggests that a single set of genes affects most cognitive
abilities and disabilities. This finding already has far-reaching implications for cognitive …

The sources of between-group variation in cognitive ability has been a source of controversy
for decades. In this pre-registered study, I tested the hypothesis that such differences are …

Cognition in adults shows variation due to developmental and degenerative components. A
recent genome-wide association study identified genetic variants for general cognitive …

Genetic variation for ability and learning is ubiquitous in animals, including in humans for
physical, cognitive and social abilities. Empirical evidence supporting the thesis that …

People's differences in cognitive functions are partly heritable and are associated with
important life outcomes. Previous genome-wide association (GWA) studies of cognitive …

A commonly held assumption in cognitive neuroscience is that, because measures of
human brain function are closer to underlying biology than distal indices of …

Although common sense suggests that environmental influences increasingly account for
individual differences in behavior as experiences accumulate during the course of life, this …

Genome-wide association (GWA) studies have uncovered DNA variants associated with
individual differences in general cognitive ability (g), but these are far from capturing …

We carried out a genome-wide association study (GWAS) for general cognitive ability (GCA)
plus three other analyses of GWAS data that aggregate the effects of multiple single …

Individual differences in human intelligence, as assessed using cognitive test scores, have a
well-replicated, hierarchical phenotypic covariance structure. They are substantially stable …
