We compare the effects of adaptive working memory training to a non-adaptive arithmetic and reading comprehension training paradigm on a variety of cognitive measures. Participants included 112 members of the University of Maryland community, 46 of whom successfully completed all of the training requirements. Participants completed a battery of cognitive tests prior to and following 20 hours of training over six weeks. Our research provides further evidence for the efficacy of adaptive working memory training for targeted working memory improvement. This study also offers support for the ability of non-adaptive arithmetic and reading comprehension training to improve general math ability and interference resolution.
