Pretty much every brain-training routine that's ever showed promise has turned out to be a practice effect specific to the task. "Does it generalize?" is the question for regimens like this. After so many promising failures, I think it's inappropriate to claim even preliminary success without looking at that question. (Worse, in fact: they ran the Trail Making Test too, saw no significant change, and declared success because scores hadn't gone down.)

Unless this stands up to a far stronger test, I'm not just dismissing the result but considering it an embarrassment for Cambridge's Neuroscience Institute, Frontiers in Behavioural Neuroscience, and ABC. Turning the results so far into a news story promising to free people from stimulants is reckless at best and dishonest at worst.
