Answer:
The phenomenom of learning that describes the best Edwina's dog behavior is Classical conditioning.
Step-by-step explanation:
To understand this process we need to remember the basics of classical conditioning. All right, classical conditioning is the learning response a certain subject manifests after he has associated one stimulus before another stimulus. In this case, we have the first stimuli, Edwina, leaving the house. However, after many experiences the dog learned that before she leaves she takes her car keys. The sound of the car keys is the second stimuli. Thus, he has learned that there is an association between both and he presents his behavior when the keys sound. This is a classic conditioning case because the key was a neutral stimulus.
