| Annotation | The effect of perceptual load on age differences in visual selective attention was examined in 2 studies. In the first study, younger and older adults made speeded choice responses indicating which of two target letters was present in a relevant set of letters in the centre of the display while they attempted to ignore an irrelevant distractor in the periphery. The perceptual load of relevant processing was manipulated by varying the central set size. When the relevant set size was small, the adverse effect of an incompatible distractor was much greater for the older participants than for the younger ones. In the second study, older adults were tested with the empty locations in the central set either unmarked (as in the first study) or marked by small circles to form a group of 6 items irrespective of set size; the two conditions did not differ markedly, ruling out an explanation based entirely on perceptual grouping.
