I somewhat recall having read or heard in some sciencey podcast something along the lines of certain tasks being more flowy in an expert-autopilot mode, if the brain was at the same time partly distracted, reducing the odds of these other brain parts minding what isn't their business/expertise and actually decreasing performance. It kind of smells like the principles of automated "muscle memory" in sports (or some other types of physical performance), versus "choking" with overthinking it. But I think it was something distinct, maybe there was the example of a famous music composer even asking someone to read something aloud to generate something that's not quite a white noise, like a secondary focus of attention, but a non-prioritary attention. And it possibly had the explanation that the "listening and making sense of words" parts of the brain being more or less distracted and interfering less with the "music composing" areas. But I'm not sure it's really something I've read or heard or whether I kind of made it up. Which wouldn't be "my theory" or anything like that, just plain confusion. Did anyone ever read something credible along those lines?
