I am a PhD student in cognitive psychology at the University Savoie Mont Blanc, France ( My research, supervised by Sophie Portrat and Pr. Pascal Hot, is about working memory and aging. More specifically, I am interested in the evolution with age of an attention-based mechanism of maintenance of information, namely attentional refreshing (Barrouillet, Portrat & Camos, 2011 ; Johnson, 1992).

Key words : working memory, complex span task, TBRS model, memory mechanisms
