Study: Does personalized brain training lead to better results than brain training sessions which are not personalized?
Result: The Karolinska Institute in Stockholm found improvements in the attention spans of both older and younger participants, as well as participants self rated cognitive skills. Personalized training was seen to be more effective than non-personalized training, and the benefits were still observed 3-months later.

Study: Can dual N-Back tasks improve attention, updating and short term memory?
Result: In a study conducted by researchers at the Washington University in St. Louis, participants showed strong transfer effects with N-Back task training, and these improvements were attributed to improvements in participant's attention span.
