Sixtine Omont




Paris Cité University

After obtaining a degree in Biology specializing in Biotechnology at the Catholic University of Lille, Sixtine obtained a master's degree in Integrative and Physiological Biology with a specialization in Behavioural and Cognitive Neurosciences at the Sorbonne University, which she will validate in 2019.
As part of her master's degree, Sixtine did a first internship with Marieke Longcamp (LNC), focusing on the development of cerebral lateralization in children and adults during handwriting. Then a second internship at LaPsyDÉ, under the supervision of Grégoire Borst, Arnaud Cachia and Emilie Salvia, on the development of cerebral lateralization of the activation network initiated by inhibitory control following executive learning in school-aged children and adolescents.
In October 2019, Sixtine begins her phD on a 3-year longitudinal study, supervised by Prof. André Knops and in collaboration with Ilse Coolen and Arnaud Viarouge. Her thesis project aims to study the contribution of 'general domain' functions to the development of digital cognition in children aged 3 to 9 years. More specifically, to study how three cognitive systems (the quantity perception system, inhibition and spatial attention abilities) contribute to digital skills from a behavioural and cerebral point of view through Magnetic Reasoning Imaging (MRI).
