Séminaire DIC-ISC-CRIA du 4 février 2021

"What do we process when we process magnitudes?" by Tali Leibovitch-Raveh 

Abstract: I will discuss the integration of non-numerical magnitudes during a quantity comparison task in humans and in an animal model – the archerfish. Then, I will discuss the influence of bottom-up and top-down factors on the automatic processing of quantities when adults are asked to compare a specific non-numerical magnitude (convex hull, total surface area or the average diameters of the dots). I will briefly present one way in which studying the influence of non-numerical magnitudes can contribute to early mathematics education.
