Genetic foundations of human intelligence.

Human genetics - 1 Jul 2009

Deary Ian J, Johnson W, Houlihan L M

Abstract excerpt

Individual differences in intelligence (cognitive abilities) are a prominent aspect of human psychology, and play a substantial role in influencing important life outcomes. Their phenotypic structure-as described by the science of psychometrics-is well understood and well replicated. Approximately half of the variance in a broad range of cognitive abilities is accounted by a general cognitive factor (g), small...
