Abstract/Description: “Brain training” claims have been the subject of many recent investigations. Proponents of brain training believe that practicing simple cognitive exercises or gamified versions of these exercises can result in improvements not just to the practiced task, but to other tasks and abilities as well. This has been termed “transfer of training.” For example, Jaeggi, Buschkuehl, Jonides, and Perrig (2008) have claimed that since working memory is vital to the performance of many different tasks, practicing working memory tasks can result in generalizable benefits. To test this idea, they had some participants practice working memory tasks while other participants received no training. At the end of the study, those participants who practiced the working memory task (a dual-N back task, to be described later) improved on two measures of fluid intelligence (Gf) while the control group did not. This finding received a great deal of attention due to previously accepted assumptions that Gf is static and cannot be improved. Similarly, Dahlin, Nyberg, Bäckman, and Neely (2008) found evidence for transfer of training as long as the practiced task and the transfer task appeared to share common neural circuits. In this fMRI study, practicing one working memory tasked improved the performance of other tasks to the extent that the practiced task and the transfer tasked relied on the striatum. Based on these and other results, some scientists argue that training can target certain cognitive abilities and neural circuits, resulting in the improved performance of other tasks that depend on overlapping abilities and circuits.
