(a, b) Diagrams reporting the time course of t-values and the related 95% confidence interval obtained comparing the receiver–observer wavelet coherence in fair (F) and hyperunfair (H) conditions at Pz location, for the Agent (a) and PC (b) conditions. The dark grey line over the x-axis indicates the interval in which wavelet coherence is statistically different between fair and hyperunfair conditions (paired t-test, alpha = 0.05 validated by means of Guthrie–Buchwald method). Scalp maps reported in the upper-right part of each panel refer to the spatial distribution of wavelet coherence at the LPP peak. The maps are seen from above, with the nose pointing to the upper part of the page. Colormap codes for the significant t-values obtained comparing wavelet coherence in fair and hyperunfair conditions within the group (paired t-test). (c) Scalp map computed at LPP peak latency reporting the significant t-values obtained comparing the receiver–observer wavelet coherence in Agent and PC conditions (paired t-test, alpha = 0.05). We performed the comparison Agent (fair VS hyperunfair) VS PC (fair vs hyperunfair).
