Show Summary Details


This chapter reviews current knowledge about the effects of normal aging on working memory and its neural underpinnings. It begins with a general overview of working memory, how it is measured by different tasks, and a controversy regarding theoretical claims about the organization of working memory. It then reviews behavioral evidence indicating how working memory changes because of normal aging. Following an overview of the working memory circuitry in younger adults, the chapter takes an in-depth look at neuroimaging studies of aging and working memory published to date, and examines how this literature can clarify each of the three issues emerging from the behavioral studies. It concludes by describing what the infusion of neuroimaging has taught us about aging working memory, revisiting the controversy about the organization of working memory, and identifying directions for future research.

Keywords: working memory; neuroimaging; cognitive aging; older adults; normal aging
