General cognitive function is substantially heritable across the human life course from
adolescence to old age. We investigated the genetic contribution to variation in this …

The genetic relationship between intelligence and components of cognition remains
controversial. Conflicting results may be a function of the limited number of methods used in …

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

General cognitive function is a prominent human trait associated with many important life
outcomes,, including longevity. The substantial heritability of general cognitive function is …

individual genes affecting intelligence. The risk inherent in such studies, however, is that
spurious associations may be picked up. The most obvious source of error is stratification …

General intelligence (g) and virtually all other behavioral traits are heritable. Associations
between g and specific single-nucleotide polymorphisms (SNPs) in several candidate genes …

Psychiatric disorders such as schizophrenia are commonly accompanied by cognitive
impairments that are treatment resistant and crucial to functional outcome. There has been …

This special review issue on Neurological and Psychiatric Diseases and Traits focuses upon
a number of phenotypes which, while very different, result from impairment of, or variation in …

Genetics and neuroscience are two areas of science that pose particular methodological
problems because they involve detecting weak signals (ie, small effects) in noisy data. In …

No one today can ignore the genetic approach to cognition and behavior, given the huge
