P3b responses.

<p>(a) ERPs averaged within the ROIs selected for P3b analysis the 500-560 ms range. Gray shadings indicate the 500-560 ms intervals where significant differences were found by ANOVA. Electrodes CP1 and P1 were selected for the left, CPz and Pz for the midline and CP2 and P2 for the right ROI. (b) Topographic maps of the P3b responses for the CW, WC, CC, and WW conditions within the 500-560 ms interval where the ANOVA yielded significant differences.</p

Frequency of closer/wider ratings (a).

<p>Mean boundary ratings across all blocks (b). Confidence ratings (c). Significant differences are indicated by asterisks (*p<0.05, ***p<0.001). Whiskers indicate standard error mean (SEM).</p

Results of mass univariate statistical analysis.

<p>(a) Each box of the raster diagram represents the results of a t-test. Black boxes indicate that the WC minus CW difference wave was significantly positive at that time point and electrode, white indicates significantly positive differences, after effectively correcting for multiple comparisons). (b) Topographic maps of WC minus CW difference potentials at timepoints within intervals where significant differences were observed. Dots mark electrodes used for mass univariate tests. White dots mark significant electrodes. (c) S2 ERPs in the WC and CW conditions. Gray shadings indicate timepoints where significant differences were found.</p
