Haha, good point! The researchers didn’t focus on how previous knowledge might interact with their effects. I guess we could be doomed but perhaps it’s not impossible to get into the multitasking mindset. There are some tasks that make me feel as though I’m multitasking even though I know I’m just quickly flicking between things (e.g. some computer games I used to play and programming-related tasks). Aiming for the impossible may give you an extra push toward your highest achievable feat!
