Age effects in cued recall: sources from implicit and explicit memory.

In 2 experiments, young and old adults were compared on cued recall using direct and indirect test instructions. Participants studied words under an incidental orienting task of rating each word for concreteness. Test cues were meaningfully related to the targets, and participants used them either to recall the studied word (direct test) or to generate a related word (indirect test). Target words and test cues varied in the number of associates linked to them prior to the laboratory experience, and effects of the size of the sets of associates were used as indicators of implicit memory search. Age differences were observed in the effects of target and cue set size as well as in the effects of type of test instruction.
