Final answer:
Jena's interest in continuing to participate in bull riding, despite the risks and injuries, is best explained by the arousal theory of motivation, which suggests an optimal level of excitement or arousal is sought after, aligning with concepts from the Yerkes-Dodson law.
Step-by-step explanation:
Jena's continued interest in bull riding is best explained by the arousal theory of motivation. This theory suggests that individuals are driven to maintain an optimal level of arousal; not too low, which would cause boredom, and not too high, which would result in stress. When Jena experiences bull riding, the high-risk activity provides a level of excitement and thrill that keeps her arousal level within an optimal range. This optimal arousal could be contributing to her enjoyment and sustained interest in the sport, even despite the injuries she faced.
The concept of the Yerkes-Dodson law is also relevant here. This law posits that for simple or well-learned tasks, a higher level of arousal can lead to better performance, whereas for more complex or novel tasks, a lower level of arousal is more beneficial. Although bull riding is not a simple task, the heightened arousal linked to the danger and public nature of the sport is likely part of the appeal for Jena, stimulating her to continue participating.
