I believe the answer is: Conditioned response
Conditioned response refers to a learned response that happen after pairing a certain trigger with a certain situation. Since maria's is used to experience the feeling of more awake after consuming coffee, the smell of the coffee itself would trigger a certain response in her brain that change her bodily function to make her feel more awake.
After Maria drank coffee for the first time in her life, she felt more awake. She then began drinking coffee every morning. Now when she even smells coffee, she feels more awake. Feeling more awake after just smelling the coffee is the conditioned response.
