Is there a decline in picture naming with advancing age?

This review of 25 studies of the picture-naming accuracy of normal aging individuals shows that an age-related decline in picture naming is an inconsistent finding. Naming performance of older adults varied throughout the studies reviewed in this paper. This variability is attributed to the research methods used and to subject characteristics. To date, there are no studies that have considered all "nuisance factors" (e.g., health status, medication) in such a way that would allow support for a decrease in picture-naming accuracy associated with primary aging.
