Abstract
Free recall of 10 series of 9 visually presented stimuli was measured for 40 young and 40 aged Ss [subjects] as a function of 2 rates and 2 schedules of stimulus presentation. Analyses of results indicated that the old groups of Ss recalled less of the stimuli than the respective young groups, but that both young and old Ss improved in performance as rate of presentation was decreased. Schedule of presentation had no consistent effect upon recall scores. Analyses of commission errors indicated that aged Ss made significantly more incorrect responses than the young. The results of both the recall scores and the commission errors were taken as support for the hypothesis that the major losses due to age are related to interference in the storage and retrieval of new information.
