Which statement correctly distinguishes classical conditioning from operant conditioning?

• A. Classical conditioning learns from consequences; operant conditioning learns by association.
• B. Classical conditioning is learning by association; operant conditioning is learning from consequences.
• C. Both rely on cognitive processes; operant uses punishment.
• D. Only classical uses reinforcement.

Answer: (B)

The key idea is how the learning process works in each type. Classical conditioning involves forming an association between two stimuli: a neutral stimulus becomes meaningful by being paired with a stimulus that already elicits a reflex, so the neutral stimulus eventually triggers the response on its own. This is learning by association.

Operant conditioning, on the other hand, is about behavior and the consequences that follow it. A behavior is strengthened or weakened based on reinforcement or punishment that follows it, so the organism learns from the outcomes of its actions.

That makes the statement that best distinguishes the two: classical conditioning is learning by association, while operant conditioning is learning from consequences. The other options mix up these ideas or add incorrect elements—classical conditioning isn’t about consequences, operant learning isn’t defined simply by punishment, and reinforcement isn’t exclusive to classical conditioning.
