Heritability of cognitive abilities in adult twins: comparison of Minnesota and Swedish data.

Behavior genetics - 1 Sept 1995

Finkel D, Pedersen N L, McGue M, McClearn G E

Abstract excerpt

Cross-sectional reports suggest heritability of cognitive ability increases throughout adulthood. To investigate this hypothesis, quantitative genetic analyses were conducted on four measures of cognitive ability (verbal, spatial, perceptual speed, memory). Data from Minnesota and Swedish twin studies of aging were compared. Heritability estimates and the factor structure of cognitive abilities could be equated...
