Answer:
generalization; extinction
Explanation:
Stimulus generalization: In psychology, the term stimulus generalization is one of the parts in the classical conditioning theory which was introduced by Ivan Pavlov, and is defined as the propensity of a conditioned stimulus or CS to trigger an exact response once the response is being conditioned.
Extinction: In psychology, the term extinction refers to the slow weakening of a conditioned response that leads to disappear or decrease the onset of a particular behavior.
In the question above, Juan's fear of all dogs illustrates generalization and Juan can be unconditioned through the process of extinction.
