Final answer:
Zajonc's social facilitation theory predicts that performance on well-learned tasks is facilitated by an audience (option 1) and that performance on novel tasks is hindered by an audience (option 3). Therefore, the correct option is 3
Step-by-step explanation:
Zajonc's social facilitation theory predicts that performance on well-learned tasks is facilitated by an audience (option 1) and that performance on novel tasks is hindered by an audience (option 3). This theory suggests that the presence of an audience can either enhance or impede performance depending on the familiarity and complexity of the task.
For example, if a person is skilled at playing the piano (a well-learned task) and performs in front of an audience, their performance is likely to be improved due to the presence of the audience. On the other hand, if a person is attempting to solve a complex mathematical problem (a novel task) in front of an audience, their performance may be hindered as the presence of the audience increases pressure and anxiety.
