Research Summary:
I am mainly interested in the development of numerical cognition in infants and children and how and why this development is impaired in developmental dyscalculia. Currently, I am investigating how the brain makes basic numerical judgments, e.g. if a given array of visual objects is smaller or larger than another, by using brain imaging techniques such as event-related potentials (ERPs). In a second line of research, I use ERPs to study how infants’ brains process time intervals. In the future, I hope to examine whether number and time share a common mechanism and how the developmental trajectory of the two might be related.
