It was hypothesized that slowed visual search in healthy adult aging arises from reduced
ability to adjust the size of the attentional focus. A novel, cued-visual search task …

The contribution of the event-related potential (ERP) research to understanding human
selective attention will be evaluated. A closely related issue, the starting point of the present …

Abstract Changes in the width of a focally attended area were assessed by analysis of
changes in reaction time associated with response-incompatible nontarget letters (flankers) …

Previous research, relying primarily on reaction time measures of highly accurate
performance, suggests that both younger and older adults can increase the efficiency of …

Age-related differences in attention to novel events were studied in well-matched,
cognitively high performing old, middle-aged and young subjects. Event-related potentials …

Reaction times (RTs), saccadic eye movements, and fixation durations were measured while
older and younger observers searched visual displays for targets defined by a single …

In the present chapter we review and critique the scientific literature that has examined age-
related changes in attention from young adulthood to old age. Owing to space limitations …

Adult age differences in the effects of different types of distractor interference on visual
search were examined. Young adults (mean age= 18.5 years) and older adults (mean age …

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 …

Three types of selective attention tasks were presented to 24 young (20.5 years) and 24
middle-aged (57.5 years) participants. The major aim of the experiment was to explore three …
