Crucially, when we tested the significance of the indirect mediation path with a Sobel test ( Sobel, 1982 , 2008 ), the marginally significant result of this effect suggests that the impact of rTPJ theta tACS on inequity aversion can statistically be explained by tACS-induced changes in perspective taking, z = 1.92, P = 0.05.
