Other Abstract

    Prospective memory involves remembering to do something in the future.There are many studies about the relation between prospective memory and aging. But there is still considerable controversy. In order to examine the  effect  of  background  task,  attention,  working  memory  load  on prospective memory and age-related difference, using the method embedding prospective memory into different background tasks (including category judgment, perception judgment, working memory),seven experiments were explored.
The results were as follows:
    1 .When the effect of background was same to the young and the old adults, there was no age difference in event-based prospective memory, but age difference was found in time-based prospective memory.
    2. The congruence of background task performance of prospective  memory.When they required different levels of process, the age difference was they required different
    3. When more attentional resource was allocated to event-based prospective memory, the performance of the young and七he old adults were improved memory.
   4. working memory load influences event-based prospective momory.When working memory  load was  high,  the  performance  of  event-based prospective memory was impaired.
    5.  Working mem6ry load affected the time-based prospective memory, and the effect was more on the old than on the young adults.In conclusion, the relationship between the event-based prospective memory and aging was  complex,even-based prospective was determined by the character of To the time-based prospective memory,there was age-related deficit. Time-based prospective memory was more sensitive to aging than event-based prospective memory. Resource deficit and attention decline were the main reasons of prospective memory aging.
