Final answer:
Coffee is the unconditioned stimulus and coffee beans are the conditioned stimulus, as the alertness is naturally caused by caffeine in coffee and associated with coffee beans over time.
Step-by-step explanation:
In the case of Kyanite feeling alert from the smell of coffee beans, the coffee itself is the unconditioned stimulus because it naturally provokes the feeling of alertness due to the presence of caffeine, a known central nervous system stimulant. Meanwhile, the coffee beans have become the conditioned stimulus because they've been associated with that state of alertness over time, although they do not contain the caffeine that triggers alertness until brewed into coffee.
In this case, kyanite drinks coffee every morning and it automatically provokes a feeling of alertness. This feeling of alertness is an unconditioned response to the unconditioned stimulus, which is the coffee. Over time, kyanite has associated the smell of coffee beans with feeling more alert. This means that the coffee beans have become a conditioned stimulus that can elicit the same feeling of alertness.
