| psychology majors, i really need your help!!!!?
i was watching an episode of 20/20 months ago and people would litter purposely to see other peoples reactions. Well one of the pedestrians started picking up the persons litter and a pyschology prof. said that she was doing it hoping to influence the other person to not litter..or realize that it was wrong..without having to say anything..just by doing it herself......
well the professor called it something..like it was a technique..i really want to know what that is called !!! i need to know..because i'm writing a paper on it..please!! help.
i guess i just need to know what it is called when you try to tell someone something by doing it..not by saying it..
