Forgetting and use of memory aids in 20 to 70 year olds everyday life.

In order to examine age differences in everyday memory experiences, twelve younger (mean age = 28) and twelve older (mean age = 59) adults kept diaries of their experiences of memory failures and use of memory aids. There was a general increase with age in the absolute number of memory failures, upset ratings about memory failures, and frequency of memory aid use. There were no age differences in the relative frequency of particular types of memory failures or memory aids that were used. The results suggested that older adults experience more memory failures and are more concerned about memory failures than younger adults, but that they attempt to deal with this problem by increased use of memory aids.
