^*P-values are from post hoc tests with Bonferroni correction performed on continuous variables or from chi-square tests performed on categorical variables (i.e., sex, handedness).

^*p < 0.05,

^**p < 0.01,

^***p < 0.001.

CVLT = California Verbal Learning Test, SD = short delay, LD = long delay, CR = cued recall.
