Dividing attention increases operational momentum [PDF]
Journal of Numerical Cognition, 2017 When adding or subtracting two quantities, adults often compute an estimated outcome that is larger or smaller, respectively, than the actual outcome, a bias referred to as “operational momentum”.

Perceived Motion and Operational Momentum: How Speed, Distance, and Time Influence Two-Digit Arithmetic [PDF]
Frontiers in Psychology, 2021 Operational momentum was originally defined as a bias toward underestimating outcomes of subtraction and overestimating outcomes of addition. It was suggested that these estimation biases are due to leftward attentional shift along the mental number-line

Operational momentum in multiplication and division? [PDF]
PLoS ONE, 2014 Biases are commonly seen in numerical cognition. The operational momentum (OM) effect shows that responses to addition and subtraction problems are biased in the whole-number direction of the operation.

The Developmental Trajectory of the Operational Momentum Effect [PDF]
Frontiers in Psychology, 2018 Mental calculation is thought to be tightly related to visuospatial abilities. One of the strongest evidence for this link is the widely replicated operational momentum (OM) effect: the tendency to overestimate the result of additions and to ...

Examining the presence and determinants of operational momentum in childhood [PDF]
Frontiers in Psychology, 2013 The operational momentum (OM) effect describes a systematic bias in estimating the outcomes of simple addition and subtraction problems. Outcomes of addition problems are overestimated while outcomes of subtraction problems are underestimated. The origin
