“…Repetition of monotonous tasks in EF training reduces motivation and increases attritionrates, and adding game-elements enhances motivation, and may improve the training effect (Prins, Dovis, Ponsioen, Ten Brink, & Van der Oord, 2011). We, therefore, used an EF training with game-elements: Braingame Brian (Prins et al, 2013), that showed promising pilot-results in ADHD (Oord, Ponsioen, Geurts, Brink, & Prins, 2012). We expected near-transfer to WM and flexibility respectively, and far-transfer to other EF tasks (inhibition, sustained attention), and to parent's ratings of daily life EFs and behavior ( Figure S1).…”
