Final answer:
Art's experience with becoming ill after eating oysters exemplifies classical conditioning where the taste of oysters acts as the unconditioned stimulus, the resulting illness serves as the unconditioned response, and any future reaction to the thought or sight of oysters represents the conditioned response.
Step-by-step explanation:
Art's experience in New Orleans with oysters illustrates the principles of classical conditioning. In classical conditioning, an unconditioned stimulus (US) produces an unconditioned response (UR) without prior training. When a neutral stimulus becomes associated with the US, it turns into a conditioned stimulus (CS) and eventually elicits a conditioned response (CR). In Art's case, initially, the taste of oysters (US) caused illness (UR), a natural reaction to possibly bad food. However, after this experience, even the thought or sight of oysters (now a CS) might cause a feeling of sickness (CR) without consuming them. This demonstrates how an unconditioned response can be transferred to a neutral or new stimulus, thereby producing a conditioned response.
