Dr. Yates claims to feel more awake and "ready to go" within 2 minutes after his first sip of coffee in the morning. Given that it takes at least 15 minutes for caffeine to reach significant levels in one's bloodstream, it is likely that Dr. Yates is experiencing a(n) response to the sight, smell, and taste of coffee.

classically conditioned

Explanation:

In classical conditioning, the conditioned response is the learned response to the previously neutral stimulus.It is all about associating a previously neutral stimulus with another stimulus that naturally produces a response. i.e two stimuli are linked together to produce a new learned response in a person or animal. In the case of Dr. Yates, the smell, sight and taste of coffee is a conditioned stimulus, a feeling of more awakenness and ready to go is the  conditioned response to the sight, smell and taste of coffee. The conditioned response would be feeling ready to go at the sight, smell and taste of coffee.
