Accuracy data for the cross-modal comparison and subtraction tasks of Experiment 3 (chance is 50%). A. Accuracy scores (mean and SEM) are plotted against the ratios of the numerosities to be compared. B. Accuracy at each comparison ratio for subtraction trials whose first array represented extreme numerical values (near the low end or the high end of the range of numerosities used) and for subtraction trials whose first array included only mid-range values. C. Accuracy at each comparison ratio for subtraction trials whose second array represented extreme numerical values (near the low end or the high end of the range of numerosities used) and for subtraction trials whose second array included only mid-range values.
