“…In our shortlisted studies, the cognitive training can be categorized as self-designed cognitive training, custom-made for the program (Barnes et al, 2009; Herrera et al, 2012; Rose et al, 2012; Bozoki et al, 2013; McAvinue et al, 2013; Corbett et al, 2015; Gooding et al, 2015; Marusic et al, 2016; Nouchi et al, 2016; Yeo et al, 2018; Requena and Rebok, 2019; Zhang et al, 2019), and as commercially-available training programs and video games (Finn and McDonald, 2011; Peretz et al, 2011; Miller et al, 2013; Strenziok et al, 2013; Ballesteros et al, 2014; Hughes et al, 2014; Hyer et al, 2015; Styliadis et al, 2015; Walton et al, 2015; Lin et al, 2016; Toril et al, 2016; Simon et al, 2018). Based on this review, self-designed cognitive training interventions demonstrated an improvement in processing speed, working memory, executive function, visual spatial ability, and attention.…”
