The proportion of working memory items recoverable from long-term memory remains fixed despite adult aging.

We explored whether long-term memory (LTM) retrieval is constrained by working memory (WM) limitations, in 80 younger and 80 older adults. Participants performed a WM task with images of unique everyday items, presented at varying set sizes. Subsequently, we tested participants' LTM for items from the WM task and examined the ratio of LTM/WM retention. While older adults' WM and LTM were generally poorer than that of younger adults, their LTM deficit was no greater than what was predicted from their WM performance. The ability to encode WM information into LTM appeared immune to age-related cognitive decline. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
