You'll see that this is exactly the same condition, only in the no-director condition they just have to remember to apply this somewhat arbitrary rule, whereas in the director condition, they have to remember to take into account the director's perspective in order to guide their ongoing behavior.
I veureu que és exactament la mateixa condició, simplement que en el grup sense director han de recordar aplicar aquesta regla arbitraria, mentre que en el grup amb director, han de recordar tindre en compte la perspectiva del director per a guiar el seu comportament.
