Final answer:
In classical conditioning, the learner perceives the conditioned stimulus to cause the conditioned response.
Step-by-step explanation:
In classical conditioning, the learner perceives the conditioned stimulus to cause the conditioned response. Classical conditioning involves pairing an unconditioned stimulus with a neutral stimulus to create a conditioned response. For example, in Pavlov's experiment with dogs, the ringing of a bell (conditioned stimulus) was paired with the presentation of food (unconditioned stimulus), resulting in the dogs salivating (conditioned response) when hearing the bell.
