FDR = false discovery rate, LFC-RFA = left frontal cathodal, right frontal anodal transcranial direct current stimulation; LFC-RPA = left frontal cathodal, right frontal anodal transcranial direct current stimulation; LPC-RPA = left parietal cathodal, right parietal anodal transcranial direct current stimulation; SE = standard error.
↵* Pairwise comparisons among estimated marginal means of pre- and post-tDCS causality judgments, for each combination of tDCS location and angle, ordered by statistical significance. FDR-adjusted p values were computed using the Benjamini–Hochberg method, to correct for performing 28 tests.
