Is there any serious research on gamification of work?

I mean, the abundance of advice that tell you that to be productive you need to cut distractions is maybe evidence of the opposite. Maybe it is deeply wrong. I am most productive when someone distracts me with urgent and somewhat game-like short task. Maybe creative one, or a small investigation.

Small tasks, small random rewards seems like way to go for me. Can we gamify most of work?
