Which of the following best represents the definition of Robert Zajonc's concept of social facilitation? A person's performance on a task is not affected by whether it is done alone or in front of a group of observers. When performing a difficult task in front of a group, a person is more likely to make more errors than they normally do. When performing an easy task in front of a group, a person will likely do better than they normally would. When performing any kind of task in front of a group, a person's dominant response for that task will be enhanced.
