We extracted signal from each ROI in the Primate > Scramble and Dog > Scramble contrasts and computed the Pearson correlation with the scores derived from the post-task emotion understanding ratings and scales on the animal-specific subscale of the IDAQ. Response pattern similarity was calculated using the Pearson correlation of the t-statistic images representing the response pattern for each Target in the Implicit Task, and then subsequently Fisher’s z-transformed for the between-subject analysis. This produced two measures of human/non-human neural similarity for each participant, which we also correlated with the collected post-task measures. L, Left; OFC, lateral orbitofrontal cortex; TPJ, temporoparietal junction; aSTS, anterior superior temporal sulcus; dmPFC, dorsomedial prefrontal cortex.
