Arnaud Viarouge


Associate professor

Paris Cité University

Arnaud is an Associate Professor in Developmental Psychology at the Paris University. He completed his PhD in Cognitive Science in 2008 at the EHESS (Paris). He then conducted postdoctoral researches at University Vanderbilt (Nashville, TN) with Dr. Bruce McCandliss, and at the Paris Descartes University with Dr. Véronique Izard. His work focuses on the development of mathematical cognition, and specifically on the origins and the development of our numérical intuitions, as well as their relations with our sensorimotor experiences. These questions led him to conduct behavioral studies on the links between the number and space in adults. He now conducts studies in the field of educational cognitive neuroscience in order to better understand the development of numerical intuitions in school-aged children, taking into account the role of domain general cognitive abilities such as inhibitory control.
