There is no obvious link to the method of the study, but the text of the study seems to imply that these tasks are some variation of "How well can you perform a task on a slightly outdated version of Microsoft Office", which these days is not widely used outside of bureaucracies, and therefore likely to be unfamiliar to most people (even for _n_x-based programmers such as myself)
I suspect if you were to give users relatively advanced tasks related to social media, online shopping, or device configuration you would get much more positive results.
