Intelligence—the ability to learn, reason and solve problems—is at the forefront of
behavioural genetic research. Intelligence is highly heritable and predicts important …

General cognitive function is a prominent and relatively stable human trait that is associated
with many important life outcomes. We combine cognitive and genetic data from the …

Importance The aging of the US population is expected to lead to a large increase in the
number of adults with dementia, but some recent studies in the United States and other high …

Abstract Narrow-sense heritability (h 2) is an important genetic parameter that quantifies the
proportion of phenotypic variance in a trait attributable to the additive genetic variation …

Over the last 10 years, high-density SNP arrays and DNA re-sequencing have illuminated
the majority of the genotypic space for a number of organisms, including humans, maize …

Intelligence is a core construct in differential psychology and behavioural genetics, and
should be so in cognitive neuroscience. It is one of the best predictors of important life …

SNP heritability, the proportion of phenotypic variance explained by SNPs, has been
reported for many hundreds of traits. Its estimation requires strong prior assumptions about …

For more than 50 years, psychologists, gerontologists, and, more recently, neuroscientists
have considered the possibility of successful aging. How to define successful aging remains …
