Memory updating practice across 100 days in the COGITO study.

We investigated working memory updating performance in younger and older adults before, during, and after 100-day practice. Performance to presentation time (PT) relation was fitted to a negatively accelerated logistic function. Relative to younger adults, older adults showed lower asymptotes at pretest and posttest, and shallower slopes at pretest. Older adults practicing the task with fast PT gained less than older adults practicing the task with slow PT, probably reflecting the persistent use of a selective strategy throughout the 100-day practice period in the fast PT group. These results have implications for designing and evaluating age-comparative working memory training programs. PsycINFO Database Record (c) 2012 APA, all rights reserved
