Which option lists all four quadrants of operant conditioning?

• A. Punishment, reinforcement, reward, correction.
• B. Positive punishment, negative punishment, positive reinforcement, incidental reinforcement.
• C. Positive reinforcement, negative reinforcement, positive punishment, negative punishment.
• D. Positive punishment, negative punishment, positive reinforcement, negative reinforcement.

Answer: (D)

Operant conditioning is organized into four quadrants based on whether a stimulus is added or removed and whether the behavior is strengthened or weakened. Positive reinforcement adds a desirable stimulus to increase a behavior. Negative reinforcement removes an aversive stimulus to increase a behavior. Positive punishment adds an aversive stimulus to decrease a behavior. Negative punishment removes a desirable stimulus to decrease a behavior. The best answer lists exactly these four terms: positive punishment, negative punishment, positive reinforcement, and negative reinforcement. It uses the standard terminology and includes all four categories, which is why it’s the correct choice. The other options either use nonstandard terms or include ideas that aren’t recognized as the formal quadrants.
