english: We obviously don't ask people to drive around and see how many car accidents they have. That would be a little costly proposition. But we design tasks on the computer where we can measure, to millisecond accuracy, how good they are at switching from one task to another.
non_english: Očigledno ne teramo ljude da se voze okolo da bismo brojali koliko će nesreća imati. Cena toga bi bila previsoka. Ali pravimo zadatke na kompjuteru gde možemo da izmerimo, precizno u milisekundu, koliko brzo oni prelaze sa jednog zadatka na drugi.
