Which of the following graphs best displays the relationship between a person's level of arousal and his or her performance on a challenging task? (A) <image 1> (B) <image 2> (C) <image 3> (D) <image 4> (E) <image 5> Answer with the option's letter from the given choices directly. No punctuation. | C Expected Answer: E Difficulty: Easy Subfield: Personality Psychology Explanation: The relationship between arousal and performance is given in the Yerkes-Dodson law, which graphs as an inverted U. This indicates that performance increases as arousal increases, but only up to a certain optimal level, after which performance declines. Thus, (E) is correct. The remaining choices are incorrect because they fail to exhibit the proper relationship. (D) might be tempting because it captures the initial increase in performance at lower levels of arousal, but it is incorrect because it does not demonstrate the whole relationship. |
