Incidental and Intentional Memory in Adulthood and Old Age.
Reese, Hayne W.; And Others
A cross-sectional study that investigated memory variables in 100 subjects in 4 age ranges (17-22, 40-50, 60-70, and 75-99) found that the 60-70 year olds were more impaired with respect to retrieval than storage and the major problem with memory among the 75-99 year olds was retrieval from short- or long-term memory. Because the study was cross-sectional, differences among the age groups do not necessarily reflect changes with age. Memory tasks in the study included the following: free recall, serial recall, delayed serial recall, and judgment of relative frequency of words, labels, digits, and events. Research participants were tested individually in two sessions in the participants' own homes or in a central location such as a testing room in a senior center, civic center, school, or motel. Each session included 12 tests. Factor analyses of variables were run separately for each age group. The principal components method was used, with varimax rotation, computed separately for each age group with the sexes combined. The first four factors accounted for about half the variance in each age group. The effects of age and sex on memory were assessed by using age group and sex as sources of variance in analyses of variance, with t-tests following up significant overall effects. (CML)
