Oof, it's hard to draw conclusions from this.

- The stuff the subjects are doing bears only a passing resemblance to the work that most of us have to do.

- Surfing the web is probably what those students are doing for breaks in work anyway on a regular basis [If you gave them no restriction, how many of them would choose surfing the web? How much is this study is just a measure of "if you let people do what they want on their breaks it's better than restricting them"]

- Were students paid differently if they performed better? Were there any incentives to perform the task at all?

- How is the control group of a study measure effectiveness of break strategies one that's doing more work? :(
