I am interested in mathematical thinking. Do children and infants possess intuitions relevant to mathematics, and what is the content of these intuitions? Are these intuitions present universally in all human beings? Conversely, what role do culture and instruction play in shaping our mathematical concepts? My research involves children and infants in France, and I have also been lucky enough to be able to study adults and children from a group in Amazonia, the Mundurucus.

Ongoing project
Geometries Return
Building on a previous ANR project (“Geometries”), this new project aims at characterizing the geometric content of form representations across a variety of formats (2D, 3D), presentation modalities (vision, touch), ages (infants, children, adults), and visual experience (sighted and blind participants).

Origin of a numerical mental line
In adults, the existence of a mental number line (the representation of smaller quantities on the left and larger quantities on the right) has been demonstrated. But what about newborns?

Numbers in Action: Origins and Dévelopental course – NUMACT
This project studies the appearance, properties and development of the link between number and the performance of an action using behavioural, electrophysiological and electromyographic measurements in human newborns and infants.
