(A) For each participant (P1–P8), performances on the Landmark task are reported, during the application of TMS over the nine spots of the grid (S1–S9) of the right PPC. The values indicate the relative percentage of difference from the baseline value. Positive values indicate rightward attentional bias (increased number of left choices as shortest segment) while negative values indicate leftward attentional bias (decreased number of left choices as shortest segment). *Significant at p < 0.05. (B) For each participant (P1–P8), performances on the Landmark task are reported, during the application of TMS over the nine spots of the grid (S1–S9) of the left PPC. The values indicate the relative percentage of difference from the baseline value. Positive values indicate higher number of left choices as shortest segment and, vice versa, negative values indicate decreased number of left choices as shortest segment. In this condition, where side of stimulation and side of segment underestimation are congruent, a positive value may either indicate a perceptual left neglect-like bias as well as a leftward response bias (see the text for further details). *Significant at p < 0.05.
