Discussion
In our research, we orthogonalized good/bad intention and good/bad outcome. We found that cathodal tDCS over the rTPJ diminished the goodness ratings towards good/bad outcomes when the intentions are good and showed no difference with ratings under bad/unknown intentions. Our results provide the first evidence that deactivation in the rTPJ disrupted intention-oriented attribution mainly by lowering the goodness ratings toward outcomes when the intentions are good, but not when the intentions are bad/unknown. Our findings argue for a causal role of the rTPJ in modulating intention attribution that may rely on the nuanced intention-outcome combinations.
