Tracking the Continuous Dynamics of Numerical Processing: A Brief Review and Editorial [PDF]

open access: yesJournal of Numerical Cognition, 2018
Many recent studies in numerical cognition have moved beyond the use of purely chronometric techniques in favor of methods which track the continuous dynamics of numerical processing. Two examples of such techniques include eye tracking and hand tracking

Is the Long-Term Association Between Symbolic Numerical Magnitude Processing and Arithmetic Bi-Directional? [PDF]

open access: yesJournal of Numerical Cognition, 2019
By analyzing longitudinal data from the start to the end of primary education, we aimed to investigate whether symbolic numerical magnitude processing at the start of primary education predicted arithmetic at the end, and whether arithmetic at the start ...

Numerical analysis of the hydrodynamic behaviour of immiscible metallic alloys in twin-screw rheomixing process [PDF]

open access: yes, 2006
A numerical analysis by a VOF method is presented for studying the hydrodynamic mechanisms of the rheomixing process by a twin-screw extruder (TSE). The simplified flow field is established based on a systematic analysis of flow features of immiscible ...
