Answer:
The conditioned stimulus is the smell of tequila.
Step-by-step explanation:
In classical conditioning, a determined behavior appears and is reinforced by the association of stimulus to a response.
- In this case we can see that the tequila was the unconditioned stimulus and the smell was a neutral stimulus.
- By mixing both stimulus, the girl vomited which was an unconditioned response.
- The nausea became a conditioned responde and the smell of tequila became a conditioned stimulus.
Given the facts, we can conclude that the conditioned stimulus now created a conditioned response, even without any drinking involved.
