Final answer:
Classical conditioning is a form of stimulus-response learning, where an organism learns to associate two stimuli that occur together, as exemplified by Pavlov's experiments with dogs.
Step-by-step explanation:
Classical conditioning is a type of associative learning where an organism learns to associate two events or stimuli that frequently occur together. This learning process was famously demonstrated by Ivan Pavlov in his experiments with dogs, where he produced a salivation response to the sound of a bell, a stimulus that originally did not elicit this response. The correct answer to the question is that classical conditioning is considered to be a form of stimulus-response learning, which is reflected in the learned association between a conditioned stimulus (e.g., a bell in Pavlov's experiment) and a conditioned response (e.g., salivation).
