The dance instructor asks his class for three volunteers to show some new moves. there are twenty people in class and everyone is silent. one girl, janie looks around the room to see if anyone is going to volunteer first. then maybe she won't have to volunteer if someone else does. which term describes why janie didn't want to volunteer? bystander effect diffusion of responsibility social facilitation conformity
