Are there any peer-reviewed studies on this? This looks like purely anecdotal evidence. It makes sense on the surface, but I don't think I can trust that four hours of intense concentration per day is some sort of "cognitive limit" without an actual scientific study.
- gwern 14y agoI don't know about writers and the morning, but there is plenty of evidence that the ideal block of learning or studying is pretty small. For example, you have spaced repetition ( http://www.gwern.net/Spaced%20repetition http://www.gwern.net/Spaced%20repetition ), where a few short minutes of studying spread out over time is vastly more efficient than a few big blocks of studying with no subsequent review sessions. And I believe there's a bunch of research on lectures becoming a waste of time after around 15-20 minutes (IIRC, FAA-sponsored).
