[The impact of aging on the ability to recognize famous faces and provide biographical knowledge of famous people].

ABSTRACTThe aim of this study was to investigate the impact of aging on the ability a) to name famous faces and b) to access biographical knowledge about famous people from different modalities of presentation (faces and names). Healthy elderly subjects (n = 117) divided into three different age groups were assessed using a semantic memory test of famous people. Results of this study indicate a decline in naming performance between oldest and youngest groups. In contrast, no difference between groups was found in terms of the ability to access semantic knowledge about famous people. Finally, a main effect of modality of presentation (faces vs. names) was found, revealing greater ability to identify famous people in the verbal (names) than in the visual modality (faces). Taken together, results of this study may contribute to developing new cognitive intervention programs in older adults presenting with proper-name anomia.
