A community-based sample of healthy, very old adults (n=224) between 75 and 96 years was presented with two lists of words: A list of semantically unrelated words and a lilst of words from four taxonomic categories ramdomly intermixed. Free recall was assessed for both tasks and, for the organizable list, subjects received a cued recall test as well. Results showed an overall age-related deteroriation of memory performance, as well as analyses of the nature of organizable free recall, suggests that problems at both decoding and retrieval may underlie teh age-related performance deficit. In addition, there were age-related increases in (a) forgetting between free and cue recall, and (b) intruison errors. Finally, regression analyses indicated thet, in addition to age, level of schooling aswell as markers of general cognitive status (the Mini-Mental State Examination) and fluid intelligence (Block Design) accounted for performance variation across all memory tasks
