I am interested in the characteristics of developmental dyscalculia and acalculia. The focus of my work is on the relations between a specific attention profile and dyscalculia.

In addition, I am interested in basic numerical processing abilities in dyscalculia and acalculia, that is, the numerical distance effect, size congruity effect, estimation abilities and subitizing.

research field: Dyscalculia, basic numerical processing and attention.
