There are three perspectives that can explain the role of arousal in social facilitation. Which summary best represents these three explanations?
O others make us alert; apprehension about being evaluated; and others are distracting
O easy tasks are made difficult if too much thought is devoted to the task; distraction from tasks positively impacts performance; we are less alert when distracted by others
O others distract us; we do not want to violate a norm by doing something wrong; we are more alert around others
O people are no more distracting than a lamp; lamps provide visual distraction; distraction from easy tasks is unlikely to impact performance
