oh my fking god. I am TRYING to do research for my book right now but I am getting DISTRACTED by the fact that I followed a citation from a paper into another paper and learned that they're interpreting EEG and eyetracking as a way to sort people into "in the flow" or "not in the flow" I AM GOING TO EFFING LOSE IT
Movement dominates brain activity, and is ALSO a huge artifact in any skin conductance. So like THAT'S a confound in these conditions. Yet no details at all about how this is truly analyzed, because it's an off the shelf EEG "band" someone bought with some research cash I bet. This paper is "we thought this was cool and so we bought a lot of stuff and tried it."
@robryk yes that's one!
