Interesting read indeed.
When I'm relaxing, I tend to have lots of sources of stimulus such as playing games while listening to a podcast. However, if the work is harder like writing articles or doing reports, I tend to switch to playing trance/techno music to shut out the world for a while and concentrate.
I think I'm averse to stimulus that requires a more intensive response (like talking to a person while doing heavy stuff) but I'm okay with having background noise.
