Intérêt de la Recherche
Je m’intéresse à mieux comprendre les limites de la perception visuelle en étudiant les différents facteurs internes (par exemple, le bruit interne) responsables de ces limites, afin de measurer l’évolution de ces facteurs au cours du développement, de l’enfance à l’âge adulte. Je m’intéresse aussi au développement neurotypique ainsi qu’au développement neurodivergent comme l’autisme.
Je suis titulaire d’une bourse postdoctorale du Fonds de Recherche du Québec.
Mots clés: perception visuelle, bruit interne, psychophysique, développement, autisme
