Wilkey, Eric D.; Shanley, Lina; Sabb, Fred; Ansari, Daniel; Cohen, Jason C.; Men, Virany; Heller, Nicole A.; Clarke, Ben – Developmental Science, 2022
Children's ability to discriminate nonsymbolic number (e.g., the number of items in a set) is a commonly studied predictor of later math skills. Number discrimination improves throughout development, but what drives this improvement is unclear. Competing theories suggest that it may be due to a sharpening numerical representation or an improved…
