Note. SMD = standardized mean difference effect size. Results are Type III fixed effects and are controlled for correlated variance of twin data. All cognitive scores were centered with a mean = 0 and standard deviation = 1.
a
Time scores were reverse-coded so that higher scores indicate better performance on all measures.
b
Remained significant after false discovery rate adjustment to p value.
