Abstract
In this chapter, we review research on the sensory and working memory changes that typically accompany normal aging, with the view that an examination of individual differences over the lifespan can illuminate some of the mechanisms underlying working memory processes. We also discuss the theoretical frameworks used to interpret these age-related changes and provide an integrated view encompassing both behavioral and brain imaging data. Behavioral data show age-related changes in both the maintenance and attention-control aspects of working memory, suggesting a balance change between the top-down and bottom-up processing streams. Brain imaging studies provide evidence for anatomical and functional changes in the brain networks associated with working memory and the top-down control of attention.
