| Outline of Final Research Achievements |
The purpose of this study was to investigate how the human brain instantiates multi-dimensional fairness decisions by taking both "equal opportunity" and "equal outcome" into account. We used functional magnetic resonance imaging (fMRI) and obtained data from forty undergraduate students. Using representational similarity analysis (RSA) of the fMRI data, we found that the neural encoding strengths in the anterior insula and ventromedial prefrontal cortex were modulated in a context-dependent manner (i.e., equal- vs. unequal-opportunity contexts). This result suggests that these two brain regions play a key role in fairness decisions where both equal opportunity and equal outcome matter.
