Final answer:
In classical conditioning, a stimulus can be produced by pairing an unconditioned stimulus (UCS) with a neutral stimulus (NS) repeatedly, resulting in the NS becoming a conditioned stimulus (CS). This elicits a conditioned response (CR) on its own.
Step-by-step explanation:
In classical conditioning, a stimulus can be produced by pairing an unconditioned stimulus (UCS) with a neutral stimulus (NS) repeatedly. This process results in the neutral stimulus becoming a conditioned stimulus (CS) that elicits a conditioned response (CR) on its own. For example, in Pavlov's experiments with dogs, the tone (NS) was paired with the meat powder (UCS) to elicit salivation (UCR). Eventually, the dogs began to salivate (CR) in response to the tone alone (CS).
