Esther Boissin



Ph.D student

Paris Cité University

After a Master’s degree in Fundamental and Applied Cognitive Sciences at the University of Lyon 2 in 2019, Esther joined LaPsyDE to do a PhD under the supervision of Wim De Neys and Serge Caparos (Université Paris 8). Her research work focuses on the characterization of intuitive processes involved in the resolution of reasoning problems. More specifically, her objectives are to determine the development of logical intuitions during childhood and adolescence, and also to understand their mechanisms in adulthood.
