Older adults often encounter difficulties in switching between tasks, perhaps because of age-
related decreases in executive function. Executive function may largely depend on …

Healthy aging simultaneously affects brain structure, brain function, and cognition. These
effects are often investigated in isolation ignoring any relationships between them. It is …

Albeit cognitive flexibility is well known to decline in aging, it has not been considered that
this ability often requires sequential task control. That is, one may re-use tasks that have …

A body of research has demonstrated age-related slowing on tasks that emphasize cognitive
control, such as task switching. However, little is known about the neural mechanisms that …

A number of theories have emerged to explain the well-studied changes in memory that
occur with age. Many of these theories invoke mechanisms that have the potential to affect …

Cognitive aging studies have suggested that older adults show declines in both sustained
and transient cognitive control processes. However, previous neuroimaging studies have …

Increased frontal cortex activation during cognitive task performance is common in aging but
remains poorly understood. Here we explored patterns of age-related frontal brain …

In this study, we used event-related brain potentials (ERPs) to examine the effects of aging
on processes underlying task switching. The response time data revealed an age-related …

Normal aging is characterized by changes in a number of cognitive processes, including
increased difficulty in maintaining information in working memory, especially in the presence …

Cognitive control involves the flexible allocation of mental resources during goal-directed
behavior and comprises three correlated but distinct domains—inhibition, shifting, and …
