Final answer:
Positive reinforcement, negative reinforcement, positive punishment, and negative punishment are four consequences that can follow a behavior in operant conditioning. Each has a specific effect on behavior.
Step-by-step explanation:
In operant conditioning, positive reinforcement, negative reinforcement, positive punishment, and negative punishment are four terms used to describe the consequences that follow a behavior. Positive reinforcement involves adding a desirable stimulus to increase a behavior, while negative reinforcement removes an aversive stimulus to increase a behavior. On the other hand, positive punishment involves adding an undesirable stimulus to decrease a behavior, and negative punishment involves removing a pleasant stimulus to decrease a behavior.
