There are now published accounts in the literature of a simple practice done for about 15 minutes, where subjects were asked to just sit quietly eyes closed and do what is sort of akin to meditation, but to not direct their mind into any particular state or place, but simply to think about their breathing and to focus on their so-called interoception, focus on how their body feels, your mind drifted to bring it back, okay? So it's basically meditation for about 15 minutes. But remarkably, just doing that once for 17 minutes, significantly reduced the number of attentional blinks that people would carry out. In other words, their focus got better in a near permanent way without any additional training.
