Final Answer:
People who are naturally more calm will be Less likely to engage in thrill-seeking behavior. Optimal arousal theory posits that individuals seek an optimal level of arousal to maintain their cognitive and physiological functioning. The correct option is b) Less likely.
Step-by-step explanation:
Optimal arousal theory posits that individuals seek an optimal level of arousal to maintain their cognitive and physiological functioning. For those who are naturally more calm, their baseline arousal level is already lower, and they may find activities with lower stimulation more satisfying and comfortable. As a result, they are less likely to engage in thrill-seeking behavior, which involves seeking higher levels of arousal.
The theory suggests that individuals strive to maintain an optimal balance, and those who are naturally more calm may achieve this balance without the need for intense or risky activities. This relationship between baseline arousal and the inclination toward thrill-seeking can be understood through the Yerkes-Dodson law, which illustrates the inverted U-shaped curve representing the relationship between arousal and performance.
Individuals with a naturally calm disposition may already be positioned on the lower end of the arousal curve, making them less inclined to seek additional stimulation. Therefore, the answer is "Less likely" as per optimal arousal theory. The correct option is b) Less likely.
In summary, the optimal arousal theory predicts that individuals who are naturally more calm will be less likely to engage in thrill-seeking behavior due to their lower baseline arousal levels.
