The temporal-parietal junction (TPJ) is a brain area implicated in social cognition, attention, integratingbody-related information and self-processing. We investigated involvement of both the left and theright TPJ in a complex social cognitive task that required attributing intentions to other people. Fourteenhealthy subjects participated in experiments that involved simulating interactions with other peoplein everyday conflicting situations. The task was performed following application of inhibitory trains ofrepetitive transcranial magnetic stimulation (rTMS) to the right and the left TPJ and to a control occipitalbrain site. Results showed a different pattern of involvement for the left and the right TPJ in judgementsrelated to social interactions. When rTMS was applied to the right TPJ, attribution of hostile intentionalityto the other increased and the tendency to interpret others’ behaviour in terms of non-hostile intentionalitydecreased. By contrast, rTMS of the left TPJ tended to produce the opposite pattern, that is, attributionof non-hostile intentionality.
