Genetic and environmental influences on intraindividual variability in reaction time.

Experimental aging research - 1 Jan 2000

Finkel Deborah, McGue Matt

Abstract excerpt

Reaction time (RT) data from the Minnesota Twin Study of Adult Development and Aging were used to investigate genetic and environmental influences on intraindividual variability in RT. The sample was 738 individuals (aged 27 to 95 years), including 185 monozygotic (MZ) and 131 dizygotic (DZ) twin pairs. Two RT factors were created: decision time and movement time. Age-corrected heritability estimates were 40% for...
