Current theories of cognitive aging argue that neural representations become less distinctive in old age, a phenomenon known as dedifferentiation. The present study used multi-voxel …

Although episodic memory and visual processing decline substantially with healthy aging, semantic knowledge is generally spared. There is evidence that older adults9 spared …
Older adults' difficulty in distinguishing between old and new information contributes to memory decline, which may occur because older adults are less likely than young adults to …

Increasing age is associated with age-related neural dedifferentiation, a reduction in the selectivity of neural representations, which has been proposed to contribute to cognitive …
Dedifferentiation, or decreased processing specificity, has been suggested to represent a ubiquitous characteristic of cognitive aging. In this study, we examined both age-related …

According to the neural dedifferentiation hypothesis, age-related reductions in the distinctiveness of neural representations contribute to sensory, cognitive, and motor declines …
The distinctiveness of neural information representation is crucial for successful memory performance but declines with advancing age. Computational models implicate age-related …
Robust evidence points to mnemonic deficits in older adults related to dedifferentiated, ie less distinct, neural responses during memory encoding. However, less is known about …

Healthy aging is associated with decreased neural selectivity (dedifferentiation) in category- selective cortical regions. This finding has prompted the suggestion that dedifferentiation …
