Research Interests

I am an experimental psychologist with a strong interest in cognitive neurosciences. My main domain of expertise concerns numerical cognition. I study numerical cognition in relation to other aspects of human cognition, such as spatial attention, working memory, hand action, synaesthesia. I am currently Marie Curie Fellow, working on the project GRINP: Grasping and Reaching In Number Processing. The GRINP project is focused on the study of the neural underpinnings of number processing and its impairment. GRINP builds upon action-based theories of cognition - considering many aspects of human cognition as built on motor action - and on the idea that the neural bases for abstract concepts representation are networks of functionally-related recycled mechanisms. Through a comprehensive approach which couples neuropsychological with neuroimaging methods, I am testing to which extent number magnitude recruits the same sensorimotor network involved in the planning and execution of hand movements.
