In Pavlov's classical conditioning, which sequence correctly describes the relationship between UCS, UCR, CS and CR?

• A. An unconditioned stimulus naturally elicits an unconditioned response; a neutral stimulus becomes a conditioned stimulus after pairing with the UCS, and then elicits a conditioned response.
• B. A conditioned stimulus naturally elicits a conditioned response; an unconditioned stimulus becomes a neutral stimulus after extinction.
• C. A neutral stimulus elicits a reflexive response without pairing; a reinforcement strengthens this response.
• D. Reinforcement schedules produce a pattern of responding.

Answer: (C)

In Pavlovian conditioning, learning happens as a neutral signal gains the power to trigger a reflex by being paired with something that naturally causes that reflex. The unconditioned stimulus naturally elicits an unconditioned response. After the neutral signal is presented together with the UCS repeatedly, it becomes a conditioned stimulus. Once this transformation has occurred, the CS alone can elicit a conditioned response, which often resembles the original unconditioned response. This sequence captures how something that started off as "neutral" becomes meaningful through association. So the best description is that a neutral stimulus, through pairing with the UCS, becomes a conditioned stimulus and then evokes a conditioned response. The idea that a neutral stimulus can elicit a reflex without any pairing mixes in concepts from operant conditioning, where reinforcement strengthens behavior rather than creating a learned association between stimuli. Additionally, extinction concerns the loss of the CR when the CS is presented without the UCS, not a change in the UCS itself.
