The correlation between the relative FC strength (to social-communicative-action system minus to manipulation-action system) during social-communicative-action perception and the relative activation strength (social-communicative-action perception minus manipulation-action perception) was highly significant (Pearson R = 0.48, p = 5.550 × 10 –225 , Fig. 5 a); Likewise, the correlation between the relative FC strength (to the manipulation-action system minus to the social-communicative-action system) during manipulation-action perception and the relative activation strength (manipulation-action perception minus social-communicative-action perception) was also significant (Pearson R = 0.486, p = 3.934 × 10 –231 , Fig. 5 b).
