Abstract

ObjectiveWe tested whether people with dementia manifest selective forgetting for self-threatening information, the mnemic neglect effect (MNE). This selective forgetting is observed among healthy adults in the recall, but not the recognition, of self-threatening feedback.MethodsSixty-four statement...
