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
Direct linkDirect link
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…

Moving Attention along the Mental Number Line in Preschool Age: Study of the Operational Momentum in 3- to 5-Year-Old Children's Non-Symbolic Arithmetic
Peer reviewed Peer reviewed
Direct linkDirect link
Haman, Maciej; Lipowska, Katarzyna – Developmental Science, 2021
People tend to underestimate subtraction and overestimate addition outcomes and to associate subtraction with the left side and addition with the right side. These two phenomena are collectively labeled 'operational momentum' (OM) and thought to have their origins in the same mechanism of 'moving attention along the mental number line'. OM in…
