Which of the following describes the yerkes-dodson law?
a. an individual’s belief in his own capabilities or capacities to complete a task influences his ability to complete the task.
b. deviations from homeostasis create physiological needs that result in psychological drive states that direct behavior to meet the need and ultimately bring the system back to homeostasis.
c. humans experience a spectrum of needs ranging from basic biological needs to social needs to self-actualization.
d. simple tasks are performed best when arousal levels are relatively high, yet complex tasks are performed best when arousal levels are low.

d) Simple tasks are performed best when arousal levels are relatively high, yet complex tasks are performed best when arousal levels are low.

Explanation:

The Yerkes-Dodson law is a law that establishes a relation between arousal and performance. According to this law, performance increases with arousal but only up to one point, once this point is reached, the performance actually decreases as the arousal continues going higher.

This law also states that different tasks require different levels of arousal for optimal performance: difficult demanding tasks may require a lower level of arousal (so the person can concentrate better), whereas easy tasks that demand persistence are better performed with higher levels of arousal (to maintain and increase motivation)

Therefore, the statement that best describes the Yerkes-Dodson law is d) Simple tasks are performed best when arousal levels are relatively high, yet complex tasks are performed best when arousal levels are low.

i'm pretty sure the answer is a
