The visual search technique was used to assess adult age differences in visual information extraction. The study included three adult age groups. In Experiment 1, participants searched for targets embedded in a list of unrelated words. Targets were defined structurally, phonemically, or semantically. Search for structural targets was faster than search for phonemic and semantic targets. This was true for all three age groups. In Experiment 2, targets were embedded in prose. The oldest age group required additional time to detect each target type, but the largest age difference was associated with semantic search.
