Human similarity judgments show substantial consistency across subjects, for all images and for most category subsets of images. The upper triangle of each matrix shows all possible pairwise inter-subject RDM correlations (Spearman r). The mirror-symmetric entries in the lower triangle of each matrix show the corresponding thresholded p-values. p-values were computed using a stimulus-label randomization test with 10,000 randomizations and corrected for multiple comparisons using the False Discovery Rate. The average of all pairwise 120 inter-subject correlations is shown below each matrix.
