My main interest is the study of cognitive processes involved in the processing of numerical information by using brain activity recording. I have been working on getting more knowledge about which factors determine the selection and the efficiency of calculation strategies used to solve simple arithmetic problems. I have also investigated whether individual differences in arithmetic competence are related with differences in the psychopsysiological responses during the performance of arithmetic tasks. Recently, my work has predominantly focused on math anxiety in order to understand the mechanisms underlying numerical processing in individuals high in math anxiety.
