Final answer:
High levels of arousal in an individual may lead to increased anxiety, which can negatively impact their performance, as supported by the Yerkes-Dodson law.
Step-by-step explanation:
An individual who has a high level of arousal may demonstrate characteristics such as increased anxiety in his or her performance. This can be explained by the Yerkes-Dodson law which suggests that there is an optimal level of arousal for peak performance. When this level is exceeded, performance tends to suffer due to factors like excessive anxiety, which can be paralyzing and hinder performance.
For example, in a softball tournament scenario where anticipation is low due to expectations of an easy win, an underwhelming level of arousal might lead to a lack of focus and a subsequent unexpected loss. Conversely, excessive stress, such as severe test anxiety, often leads to negative emotions and physical symptoms that interfere with concentration and performance.
