Does working memory training generalize?

Abstract

Recently, attempts have been made to alter the capacity of working memory (WMC) through extensive practice on adaptive working memory tasks that adjust difficulty in response to user performance. We discuss the design criteria required to claim validity as well as generalizability and how recent studies do or do not satisfy those criteria. It is concluded that, as of yet, the results are inconsistent and this is likely driven by inadequate controls and ineffective measurement of the cognitive abilities of interest.
