Little is known about the genetic architecture of traits affecting educational attainment other
than cognitive ability. We used genomic structural equation modeling and prior genome …

Cognitive deficits and reduced educational achievement are common in psychiatric illness;
understanding the genetic basis of cognitive and educational deficits may be informative …

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

General cognitive ability (g), which refers to what cognitive abilities have in common, is an
important target for molecular genetic research because multivariate quantitative genetic …

Intelligence is a highly polygenic trait and genome-wide association studies (GWAS) have
identified thousands of DNA variants contributing with small effects. Polygenic scores (PGS) …

Weak widespread (polygenic) selection is a mechanism that acts on multiple SNPs
simultaneously. The aim of this paper is to suggest a methodology to detect signals of …

One surprising feature of the recently completed waves of genome-wide association studies
is the limited impact of common genetic variation in individually detectable polymorphisms …

All measures of cognitive processes correlate moderately at the phenotypic level and
correlate substantially at the genetic level. General cognitive ability (g) refers to what diverse …

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

People who score higher on intelligence tests tend to have larger brains. Twin studies
suggest the same genetic factors influence both brain size and intelligence. This has led to …
