Susie is a conscientious student and wants to perform well on exams in her biology course. Susie did not sleep well the night before the final exam due to a loud party nearby; she then overslept her alarm the morning of the exam.

When she went to the classroom to take the exam, she was highly aroused. What would the Yerkes-Dodson law predict will be the effect of her arousal on exam performance?

1.) Susie is highly aroused and engaging in a difficult task; the Yerkes-Dodson law predicts no effect on performance since she is a conscientious student.

2.) Susie is highly aroused and engaging in a difficult task; therefore, the Yerkes-Dodson law predicts her performance will be high.

3.)Susie is highly aroused and engaging in a difficult task; therefore, the Yerkes-Dodson law predicts her performance will be low.

4.) Susie is highly aroused and engaging in a simple task; therefore, the Yerkes-Dodson law predicts her performance will be low.

According to the Yerkes-Dodson law, performance on a difficult task is

1.) impaired by low levels and high levels of arousal and maximized by moderate levels of arousal.

2.) impaired by low levels, moderate levels, and high levels of arousal.
3.) impaired by high levels of arousal and maximized by low levels and moderate levels of arousal.

4.) impaired by low levels of arousal and maximized by high levels and moderate levels of arousal.
