Genetic variance in processing speed drives variation in aging of spatial and memory abilities.

Developmental psychology - 1 May 2009

Abstract excerpt

Previous analyses have identified a genetic contribution to the correlation between declines with age in processing speed and higher cognitive abilities. The goal of the current analysis was to apply the biometric dual change score model to consider the possibility of temporal dynamics underlying the genetic covariance between aging trajectories for processing speed and cognitive abilities. Longitudinal twin data...
