Abstract

This chapter examines the question of how the features or elements (e.g. shape, color, or spatial location) of a stimulus that is encountered in the visual environment are bound together in working memory to form an integrated representation. We first briefly review recent research on this topic in healthy young adults, examining the factors that determine successful encoding and retention in working memory. A particular focus of the chapter concerns how this key cognitive process (or set of processes) might vary as a function of healthy cognitive aging, and of neuropsychological disorders typically associated with aging (e.g. Alzheimer's disease). It appears that while older adults typically show associative deficits in long-term memory, age-related binding deficits in working memory are somewhat inconsistent in nature, and may depend to some extent on the form of binding being examined.
