Research Interests :

My main research interests concern the typical and atypical development of numerical abilities.

Presently, my researches focus on the development of basic numerical processes in children and adults with genetic (Williams, 22q11 or Turner syndromes) or congenital (spina bifida) disorders known to be recurrently associated with specific mathematical learning disabilities. More specifically, the ongoing behavioral studies conducted in these populations are designed to examine:

- non-numerical quantitative processing

- symbolic and non-symbolic numerical processing

- and the impact of associated visuo-spatial deficit on numerical and non numerical quantitative processing.   

I'm also interested in :

- the existence of an innate and amodal representation of numerical magnitude

- the place of perceptual processing in our ability form an abstract representation of numerosity

- the role of fingers in the emergence of a full-blown, cardinal representation of numerosity in the course of development.
