Age-related deficits in guided search using cues

The ability of young and older adults to engage in guided conjunction search was tested in 2 experiments. In the cued condition, a picture of the target was presented before the search. In the noncued condition, there was no picture of the target. In Experiment 1, the cue was presented for 200 ms; the magnitude of the cuing effect (noncued response time -cued response time) was greater for the young than for the older observers. In Experiment 2 (older observers only), the cue duration was

The results indicated that older observers had difficulty with interpreting the cue and setting search parameters when the target varied across trials.
