BIOGRAPHIE

Avant d’entrer au service de l’École de psychologie à titre de professeur adjoint en 2011, monsieur Vachon a obtenu en 2007 son doctorat en psychologie de l’Université Laval avant d’effectuer des stages postdoctoraux—subventionnés par le CRNSG et le FQRNT— en psychologie cognitive à Cardiff University au Royaume-Uni (2007), en neuroscience cognitive à l’Université de Montréal (2008-2009) ainsi qu’en facteurs humains à l’Université Laval (2009-2011). Spécialisé en science cognitive fondamentale et appliquée et membre du Groupe de recherche en psychologie cognitive (GRPC) de l’Université Laval, ses intérêts de recherche touchent plus particulièrement la psychologie cognitive de l’attention. Son programme de recherche porte sur l’étude des mécanismes fondamentaux du déplacement volontaire (contrôle) et involontaire (perte de contrôle) de l’attention et comporte deux principaux thèmes : l’étude de l’adaptabilité et de la flexibilité en situation multitâche et l’étude des effets de la distraction auditive (p. ex., capture attentionnelle) sur la performance. Monsieur Vachon s’intéresse également au domaine de l’ergonomie cognitive (facteurs humains) qui vise l’optimisation de la performance humaine. Dans le cadre de ses travaux, il combine les mesures comportementales traditionnelles (erreurs, temps de réponse) à l’analyse de l’activité cérébrale (EEG, potentiels évoqués) et au suivi du mouvement oculaire. Il enseigne la psychologie cognitive à tous les cycles. En 2016, la Faculté des sciences sociales lui remet le Prix d’excellence en enseignement dans la catégorie des professeurs adjoints.
