Research Topics

Je m’intéresse au fonctionnement de la mémoire de travail avec une approche expérimentale, développementale et de modélisation computationnelle. En particulier, quelques mots-clés ci-dessous

  • processus et stratégies de maintien à court terme (refreshing, rehearsal, chunking, elaboration)
  • coût cognitif et contrôle attentionnel
  • vieillissement normal et pathologique
  • lien entre mémoire de travail et mémoire à long terme
  • stimulation cognitive et sportive

I am interested in working memory functionning with an experimental, developpmental and computational approach. Some keywords bellow

  • Maintenance mechanisms and strategies in WM (refreshing, rehearsal, chunking, elaboration)
  • Cognitive load and controlled attention
  • Normal and pathological WM aging
  • Relationship between WM and long-term memory
  • Cognitive and Sports stimulation
