Which learning theory demonstrates how behaviors are strengthened or weakened through consequences?

• A. Classical conditioning
• B. Direct instruction
• C. Operant conditioning
• D. Reinforcement

Answer: (C)

Consequences shaping behavior through reinforcement and punishment is what operant conditioning explains. This theory shows how the likelihood of a behavior changes based on what happens after the behavior occurs: positive reinforcement adds a pleasant outcome to increase the behavior, while punishment or negative consequences decrease it. This framework covers a range of mechanisms, including reinforcement, punishment, extinction, and discrimination, all tied to how the environment’s consequences shape future responses.

Classical conditioning, by contrast, focuses on forming associations between stimuli rather than the consequences of the behavior itself. Direct instruction is a teaching method, not a theory about how consequences influence behavior. Reinforcement is a component of operant conditioning, but on its own it doesn’t describe the full mechanism by which consequences strengthen or weaken behavior. That broader explanatory power is why operant conditioning is the best answer.
