Final answer:
In the language of classical conditioning, dogs have become a conditioned stimulus for Jenny, triggering a conditioned response of fear and shaking due to her past experiences of being bitten.
Step-by-step explanation:
Jenny's extreme phobia for dogs is an example of classical conditioning. In this context, dogs have become a conditioned stimulus. Originally, Jenny's experiences with dogs involved being bitten, which is an unconditioned stimulus that naturally elicited a fear response, the unconditioned response. After several instances of being bitten, the mere presence of dogs, previously a neutral stimulus, has now been associated with the fear and pain of the bites. Seeing a dog now triggers a fear response in Jenny, making the sight of a dog a conditioned stimulus that elicits a conditioned response, which in Jenny's case, is shaking and extreme fear.
The process Jenny experienced is similar to the experiments conducted by Pavlov with his dogs, where a neutral stimulus (the sound of a bell) when paired with an unconditioned stimulus (food), eventually became a conditioned stimulus causing a conditioned response (salivation) without the presence of food. Extending the understanding of classical conditioning, Jenny's reaction to dogs similarly became a conditioned response through the repeated pairing of the unconditioned stimulus (dog bites) with the previous neutral stimulus (the sight of a dog).
