This study compares brain activation during causal attribution to three different loci, the self, another person and the situation; and further explores correlations with clinical scales (i.e. depression, anxiety and autism) in a typical population. While they underwent functional magnetic resonance imaging, 20 participants read short sentences about another person ( someone ) who engaged in behaviors with the participant or made comments about the participant. The participants then attributed these behaviors to three attribution loci: themselves, the other person or the situation. The results revealed common activation across the three attribution loci in the bilateral temporo-parietal junction (TPJ), left posterior superior temporal sulcus, precuneus and right temporal pole (TP). Comparisons between the attribution loci revealed very little differences, except for increased activation of the right TP while making attributions to the situation compared with the self. In addition, when making attributions to the situation or other persons for negative events, there were reliable correlations between low activity in the left TPJ and high levels of anxiety and problematic social interaction in autism. The results indicate that attributions to different loci are based on the same underlying brain process, which might be atypical among persons with anxiety or autism symptoms.
