University of Poitiers 2 articles published in JoVE Behavior Highlighting and Reducing the Impact of Negative Aging Stereotypes During Older Adults' Cognitive Testing Marie Mazerolle1, Isabelle Régner2, François Rigalleau3, Pascal Huguet4 1Department and Laboratory of Psychology, MSHE, Université Bourgogne Franche-Comté, 2Aix-Marseille University, CNRS, LPC, 3Department of Psychology, University of Poitiers, CNRS, 4University of Clermont Auvergne, CNRS, LAPSCO Here, we present a protocol designed to show how negative aging stereotypes can impair memory performance of older adults during cognitive testing and how to reduce this deleterious effect. This method can help older people to perform at an optimal level during testing in both lab studies and clinical settings.
