Hyper-Focusing (Score 3, Interesting)

This article doesn't mention how this can relate to what is known as "hyper-focusing." Maybe this is what they mean by "zoning out" since the medical information is scarce, but there is a phenomenon observed in ADHD sufferers that shows while playing video games (and some other activities) they focus to the exclusion of all other stimuli, often for extended periods of time. I'm not sure if this is the same thing or a seperate symptom than "zoning out" but it might be worth looking into a bit more.
