Guez, Ava; Piazza, Manuela; Pinheiro-Chagas, Pedro; Peyre, Hugo; Heude, Barbara; Ramus, Franck – Developmental Science, 2023
A converging body of evidence from neuroimaging, behavioral, and neuropsychology studies suggests that different arithmetic operations rely on distinct neuro-cognitive processes: while addition and subtraction may rely more on visuospatial reasoning, multiplication would depend more on verbal abilities. In this paper, we tested this hypothesis in…

Preschoolers Prior Formal Mathematics Education Engage Numerical Magnitude Representation Rather than Counting Principles in Symbolic ±1 Arithmetic: Evidence from the Operational Momentum Effect
Peer reviewed Peer reviewed

Haman, Maciej; Lipowska, Katarzyna – Developmental Science, 2023
In numerical cognition research, the operational momentum (OM) phenomenon (tendency to overestimate the results of addition and/or binding addition to the right side and underestimating subtraction and/or binding it to the left side) can help illuminate the most basic representations and processes of mental arithmetic and their development. This…

Brain Hyper-Connectivity and Operation-Specific Deficits during Arithmetic Problem Solving in Children with Developmental Dyscalculia
Peer reviewed Peer reviewed

Rosenberg-Lee, Miriam; Ashkenazi, Sarit; Chen, Tianwen; Young, Christina B.; Geary, David C.; Menon, Vinod – Developmental Science, 2015
Developmental dyscalculia (DD) is marked by specific deficits in processing numerical and mathematical information despite normal intelligence (IQ) and reading ability. We examined how brain circuits used by young children with DD to solve simple addition and subtraction problems differ from those used by typically developing (TD) children who…
