This fMRI study aimed to explore the effect of normal aging on word retrieval and generation.
The question addressed is whether lexical production decline is determined by a direct …

Speech recognition in noise can be challenging for older adults and elicits elevated activity
throughout a cingulo-opercular network that is hypothesized to monitor and modify …

There is considerable debate about whether additional fMRI-measured activity in the right
prefrontal cortex readily observed in older adults represents compensatory activation that …

Five nonfluent aphasia patients participated in a picture-naming treatment that used an
intention manipulation (opening a box and pressing a button on a device in the box with the …

Aging involves many cognitive declines, particularly in fluid intelligence, with relative
maintenance of crystallized intelligence. This paradox is evident in the language domain …

Aims The prevalence of white matter hyperintensities (WMH) rises dramatically with aging.
Both the progression of WMH and changing patterns of default mode network (DMN) have …

Typically, thalamic aphasias appear to be primarily lexical-semantic disorders representing
difficulty using stored declarative memories for semantic information to access lexical word …

ABSTRACT Background/Study Context: Lexical retrieval abilities and executive function
skills decline with age. The extent to which these processes might be interdependent …

As the passage of time structurally alters one's brain, cognition does not have to suffer the
same faith, at least not to the same extent. Indeed, the existence of age-related …

Purpose When speakers retrieve words, they do so extremely quickly and accurately—both
speed and accuracy of word retrieval are compromised in persons with aphasia (PWA). This …
