Visual attention and aging

Visual attention and aging.

The present review of visual attentional processes and aging focuses on definitions of attention that emphasize some aspect of the control of information processing (selective attention) or the processing resources needed to drive these control processes (attentional capacity). Emphasis is placed on how increased adult age affects attentional mechanisms and how these age differences in attentio...

Aging and Visual Attention.

Older adults are often slower and less accurate than are younger adults in performing visual-search tasks, suggesting an age-related decline in attentional functioning. Age-related decline in attention, however, is not entirely pervasive. Visual search that is based on the observer's expectations (i.e., top-down attention) is relatively preserved as a function of adult age. Neuroimaging researc...

Normal aging selectively diminishes alpha lateralization in visual spatial attention

EEG studies of cue-induced visual alpha power (8-13 Hz) lateralization have been conducted on young adults without examining differences that may develop as a consequence of normal aging. Here, we examined age-related differences in spatial attention by comparing healthy older and younger adults. Our key finding is that cue-induced alpha power lateralization was observed in younger, but not old...

Aging and Attention

A Aging and Attention

In everyday life, people often refer to attention as if it were a single, unitary thing, such as a vat of energy that can be spread across stimuli or tasks. Research suggests otherwise (Nobre and Kastner 2014). There appear to be many different limited mental resources associated with different brain networks and pertaining to different levels of processing (e.g., spatial vs. central) that can ...
