Continuous Quantity Type: (A) Dot size, summed dot area, total contour length, and density are positively correlated with number while array size is correlated negatively with number; (B) Dot size, summed dot area, total contour length, and density are negatively correlated with number while array size is positively correlated with number.
*
Indicates whether the addend or foil predicts the correct answer according to the range strategy tested above (see Table A2).
