Questions: The relationship between arousal and performance forms a(n)

The answer is the third one (or C): inverted U function.

Explanation for each option: a. U function: This suggests that performance increases, then decreases, forming a U shape. This is not correct in the context of arousal and performance. b. exponential relationship: This implies that performance increases exponentially with arousal, which is not accurate for this context. c. inverted U function: This is correct. The Yerkes-Dodson Law states that there is an optimal level of arousal for peak performance, and both too little and too much arousal can lead to poorer performance, forming an inverted U shape. d. linear relationship: This suggests a direct, proportional relationship between arousal and performance, which is not accurate according to the Yerkes-Dodson Law.

Summary: The relationship between arousal and performance forms an inverted U function, indicating that there is an optimal level of arousal for peak performance, with both low and high levels of arousal leading to decreased performance.
