Well, what you do is, if you take any one of you here, and put you in front of a screen, and measure your galvanic skin response, and show pictures on the screen, I can measure how you sweat when you see an object, like a table or an umbrella. Of course, you don't sweat.
Kada biste bilo koga od prisutnih stavili ispred ekrana i mjerili galvansku reakciju kože te prikazali slike na ekranu mogao bi izmjeriti kako se znojite kada vidite objekt poput slola ili kišobrana -- naravno, ne znojite se.
