Figure 7. Number drove classification performance in EVC while controlling for eight non-numerical features.

Mean SVM classification accuracy on pair-wise comparisons where number changed by a 2:1 ratio, but the non-numerical stimulus feature on the x-axis was held constant. The process was repeated for the whole brain significant cluster (Figure 2) and the subject specific parietal localizer ROIs. Error bars indicate standard error across subjects. * p < 0.05; ** p < 0.01; *** p < 0.001.
