This study aims to investigate the relation between brain region right temporoparietal junction (rTPJ) and the processing of moral judgment on fictional stories. Previous stories have shown that rTPJ is related to the ability of perceiving and reasoning people's thoughts, and empathy, but there lacks a direct causal link from neurology to psychology. The study used transcranial magnetic stimulation (TMS) to disrupt the brain region while participants were judging people's story and 'my' story, and recorded the changes of response time and moral scores. Sham stimulation was produced by the same apparatus in both TMS conditions, and 8 levels of crime were tested in the experiment. The results showed a varying impact of TMS on the speed of moral judgment and moral scores, presenting the important role that rTPJ played in the function of moral judgment.
