For each component, paired effect and statistic underlining indicates a reversal of that effect. Reversals of any two directional indicators within an effect indicate a statistically equivalent interpretation. Bolded p-values indicate dominant topography used as a guide to select sites analyzed. F, frontal; P, parietal; C, central; L, left; R, right; M, midline; < and > indicate direction of effect; and × denotes interactions. All F-tests are reported with (1, 46) degrees of freedom.
