The longitudinal relationship between processing speed and cognitive ability: genetic and environmental influences.

Behavior genetics - 1 Sept 2005

Finkel Deborah, Reynolds Chandra A, McArdle John J, Pedersen Nancy L

Abstract excerpt

Goals of the present study were to investigate the relationship between age changes in speed and cognition and the genetic and environmental influences on that relationship. Latent growth models and quantitative genetic methods were applied to data from the Swedish Adoption/Twin Study of Aging. The sample included 778 individuals from both complete and incomplete twin pairs who participated in at least 1 of 4...
