| Annotation | Research on the possible age-related decline or slowing of visual attention have resulted in conflicting conclusions. This study investigated adult age differences in the time course of the allocation of visual attention in two experiments that both included the same younger (aged 19-28) and older (aged 65-70). In experiment one, older adults accumulated information about target identity at a slower rate than younger adults, as represented by the rise in accuracy as a function of target duration. In experiment two, target duration was set for each observer on the basis of the data in experiment one in order to equate performance in a baseline condition in a spatial-cuing paradigm. Performance for the two age groups were comparable, both in the baseline condition and in the time course of attention, as indexed by function relating accuracy to cue-target onset asynchrony. The study concluded that, in this spatial-cuing paradigm, an age-related change was evident in sensory processing but not in attentional allocation. (AKM). |
