Leib, Elena R.; Starr, Ariel; Younger, Jessica Wise; Bunge, Silvia A.; Uncapher, Melina R.; Rosenberg-Lee, Miriam – Developmental Psychology, 2023
The present study tests two predictions stemming from the hypothesis that a source of difficulty with rational numbers is interference from whole number magnitude knowledge. First, inhibitory control should be an independent predictor of fraction understanding, even after controlling for working memory. Second, if the source of interference is…

Wilkey, Eric D.; Pollack, Courtney; Price, Gavin R. – Child Development, 2020
Deficits in numerical magnitude perception characterize the mathematics learning disability developmental dyscalculia (DD), but recent studies suggest the relation stems from inhibitory control demands from incongruent visual cues in the nonsymbolic number comparison task. This study investigated the relation among magnitude perception during…
