In the total filled area control, cardinality knowledge was the only significant predictor when children saw comparisons involving the 2:3 (β = 0.62; p = 0.005) and 3:4 (β = 0.73; p < 0.001) ratios, while in the 1:2 ratio, cardinality knowledge was marginally significant (β = 0.44; p = 0.051): CP-knowers are better at discriminating two quantities involving 2:3 and 3:4 ratios than non-CP-knowers.
