Central/incidental recall and selective attention in young and elderly adults.

Central and incidental recall of young (Mean age=28.4) and elderly (Mean age=70.9) men and women was examined. As expected, statistically significant age differences were found for both central and incidental recall. For the eight items mean central recall (5.72) was significantly higher than mean incidental recall (2.56) at both age levels; mean incidental recall was significantly greater than chance for both age groups. Lack of an age X central/incidental interaction was interpreted as supporting a general recall deficit. No evidence was found to suggest an attentional focusing difference between young and elderly adults. Verbal labeling of the central stimuli had no effect on recall scores. Differential recall for each of eight positions of stimuli was also examined. Both age groups exhibited a spatial primacy-recency effect for central but not incidental recall. No support was obtained for an attentional interpretation of age-associated differences in learning.
