We evaluated the dependent variable sin+sout of each single subject within the couple (n = 52) for the six specific ROIs (ANOVA's first independent variable: ROI factor) and for the three pure strategies (ANOVA's second independent variable: TASK factor). Each frequency band has been considered separately (see Supplementary Material for details). This statistical test showed that different TASKs induce statistically significant differences (p≪0.001) in the distribution of total strength, regardless of the ROIs, for all the frequency bands. Conversely, different ROIs exhibit statistically significant differences (p≪0.001) in total strength, for all the frequency bands, except Alpha. The interaction of the two factors, instead, produces statistically significant differences (p≪0.001) only in the Beta and in the Gamma band (see Table S2).
