Note: TF Contrasts for each cluster as obtained after running tests on theta, alpha, and low beta frequency bands separately, are indicated as detected by the two-tailed non-parametric cluster-based permutation tests. Congruence contrasts (congruent minus incongruent), congruence by age interaction contrasts (Congruence contrast in young group minus congruence contrast in older participant group), DM contrasts (remembered minus forgotten), DM by age interaction contrasts (DM contrast in young group minus DM contrast in older participant group), and congruence by DM interaction contrasts (DM contrast for congruent words minus DM contrast for incongruent words) are shown. The duration in ms, the frequency range in Hz, and the list of electrodes which were returned by the computation for each cluster, are shown together with the significance level.
