Sources of influence on rate of cognitive change over time in Swedish twins: an application of latent growth models.

Experimental aging research - 1 Jan 2000

Reynolds Chandra A, Finkel Deborah, Gatz Margaret, Pedersen Nancy L

Abstract excerpt

The use of latent growth models to examine influence on individual differences on ability level versus rate of change were examined for measures of fluid ability, memory, and perceptual speed in a sample of twins from the Swedish Adoption/Twin Study of Aging. Results indicated a larger amount of individual variation for average ability level (i.e., intercept) than rate of change (i.e., slope) for all three...
