Number of significant sites observed for each (morpho)phonological comparison for each neural response band relative to the generated null distribution for that band. Each null distribution (grays) contains 1000 comparisons. Vertical axes indicate the number of sites selective for surface identity observed for each comparison, while horizontal axes indicate the number of sites selective for underlying identity observed for each comparison. The proportion of the null distribution that contains at least as many surface and underlying sites as were observed for each comparison is indicated in the top right corner of each plot. Values for the tap comparison are blue; values for the past tense comparison are red; and values for the plural comparison are green. Dashed gold lines delimit the boundary containing 95% of the null distribution. Additional detail for each of the three comparisons is given in Supplementary Figs. 4–7.
